Deca Durabolin (Nandrolone Decanoate) is an injectable anabolic steroid, typically utilized by bodybuilders in the off-season for mass building.
Deca Durabolin was first described in 1960 with pharmaceutical giant, Organon, bringing it to market 2 years later.
Deca Durabolin was Organon’s second formulated nandrolone ester, following Nandrolone Phenylpropionate (NPP).
Deca Durabolin was initially synthesized to treat patients suffering from cachexia (muscle wasting).
It is one of the only anabolic steroids still prescribed today, effectively treating HIV/AIDS and anemia patients, thanks to its anabolic and erythrocytosis properties.
By the 1970s Deca Durabolin had become one of the most popular anabolic steroids in the world (which remains the case today). It was known to be cycled by top bodybuilders during the golden era (such as Arnold Schwarzenegger), commonly being stacked alongside Dianabol during bulking cycles.

Legal Deca Durabolin Alternative

DecaDuro is our #1 rated legal Deca Durabolin product. It replicates the muscle-building and strength-enhancing effects of Deca, but without the unwanted side effects.

It is FDA-approved and can be purchased online without a prescription.

DecaDuro is best suited for men wanting to build significant amounts of muscle; without shutting down their testosterone, causing erectile dysfunction or elevating blood pressure levels.

Deca Durabolin Benefits
Muscular Size and Strength
Deca Durabolin promotes muscular hypertrophy (size) and strength, causing significant changes in body composition after several weeks of use.
Deca Durabolin promotes lean mass, due to it stimulating protein synthesis and creating a positive nitrogen balance inside the muscle cells.
It is not as potent as other bulking AAS (anabolic-androgenic steroids), such as Anadrol, Dianabol, Superdrol or Trenbolone.
However, some bodybuilders prefer Deca Durabolin over such steroids, due to its safety profile.
Well Tolerated
It is an FDA-approved medicine, which is indicative of its low-risk level. It has been successfully prescribed to women for breast cancer treatment (1) and children suffering from dwarfism (2); without notable adverse effects.
Deca Durabolin also increases collagen synthesis, improving the health of ligaments and tendons. This is particularly beneficial to bodybuilders and powerlifters regularly lifting heavy weights and thus being more prone to injury.
Joint Anti-Inflammatory
Deca Durabolin also promotes fluid retention, that aids in lubricating the joints. This can help to minimize, alleviate or prevent joint pain in bodybuilders who have lifted weights for many years.
In one study, Deca Durabolin was given to 18 men experiencing joint pain. Following treatment, 72% reported a reduction in pain and 28% required less painkiller medication (3), demonstrating potent anti-inflammatory effects of the steroid.
No Hepatotoxic Effects
Many steroids, particularly orals, can exhibit toxic effects on the liver.
If abused, such AAS can cause peliosis hepatis (blood-filled cysts) or cirrhosis (failure) of the liver.
However, Deca Durabolin is an injectable steroid that bypasses the liver, causing little to no hepatic strain.
Long Esters
Deca Durabolin is a slow-acting steroid, containing long esters, hence why cycles typically last up to 12 weeks.
This can be disadvantageous to some bodybuilders looking for rapid results, but for others who want serum testosterone levels to remain steady in the bloodstream (to minimize side effects); this is largely beneficial.
Furthermore, when Deca Durabolin is stacked with other steroids, it enables users to continue experiencing results in the latter stages of a cycle. In comparison, other AAS can peak early or cause more side effects than benefits towards the end of a cycle, due to high levels of toxicity.
Deca Durabolin Side Effects
Cholesterol
Deca Durabolin will cause mild alterations in LDL/HDL cholesterol scores, provoking elevations in blood pressure. However, the risks of developing heart disease are relatively low on Deca Durabolin, with such cardiac effects being mild.
All anabolic steroids will have a negative effect on blood lipids, as they are all essentially forms of exogenous testosterone. However, Deca Durabolin is among the most cardiovascular-friendly steroids available (alongside Testosterone).
Deca Dick
Deca Durabolin is infamous for its sexual side effects, including a decrease in sexual desire and performance; often leading to erectile dysfunction (Deca dick).
The reason why men may struggle to get an erection on Deca Durabolin is due to its deficiency in androgenicity. Androgenic steroids facilitate nitric oxide production, which is crucial in the role of supplying blood flow to the penis. Thus, Deca Durabolin may compromise circulation in this regard.
Also, Deca Durabolin raises prolactin levels, a lactating hormone, that can decrease arousal or sexual interest.
This combination of low nitric oxide levels and high prolactin is often a recipe for disaster in the bedroom.
However, bodybuilders often combat this by stacking Deca Durabolin with an androgenic steroid, ensuring that N.O levels stay high. Examples of such androgenic compounds are Testosterone, Anadrol and Trenbolone.
Bodybuilders may also supplement with cabergoline (when taking Deca), due to its prolactin-lowering effects, caused by it strongly binding to dopamine receptors.
Low Testosterone
Low testosterone levels will occur on Deca Durabolin, with it being a highly suppressive anabolic steroid.
Thus, a PCT involving Tamoxifen (Nolvadex) or Clomiphene (Clomid) may be administered to help stimulate endogenous testosterone production, following discontinuation of the drug.
Estrogen and Progesterone
Deca Durabolin has low estrogenic properties, with just a 20% aromatization rate of testosterone. However, Deca Durabolin users can often experience estrogen-like side effects; due to it significantly increasing progesterone.
Progesterone is a female sex hormone (like estrogen) that has a stimulating effect on breast tissue in the mammary glands, potentially causing gynecomastia.
Interestingly, anti-estrogens (such as anastrozole) are effective inhibitors of progesterone receptor expression and thus reduce the risk of gynecomastia in men (4).

Deca Durabolin Cycles
Deca Durabolin-Only Cycle
Deca Durabolin is predominantly used for bulking purposes; however, due to it only building moderate amounts of lean muscle (by bodybuilding standards), it is often cycled with other, more potent AAS.
Generally stacking steroids together leads to an increase in side effects, such as further elevations in cholesterol. However, in Deca Durabolin’s case, stacking may help to prevent some of its negative effects regarding sexual health.
Thus, Deca Durabolin-only cycles are seldom among bodybuilders, in a bid to keep androgen levels high, mitigating the risk of erectile dysfunction on-cycle.
However, if a bodybuilder were to utilize a Deca Durabolin-only cycle, these are the typical dosages they would use (below):

Deca Durabolin and Dianabol Cycle
Dianabol (Methandrostenolone) is one of the most popular steroids available, due to its exceptional mass-building effects.
Dianabol сompliments Deca Durabolin during a bulking cycle, with Deca Durabolin amplifying the anabolic nature of Dianabol, enhancing muscle hypertrophy (size) and strength.
Dianabol’s two main adverse effects are hypertension and liver toxicity. Thus, by stacking Dianabol with Deca Durabolin, users will not be aggravating these two symptoms; with Deca being an injectable and only having mild effects on blood lipids.

This steroid cycle is taken by experienced steroid users, who already have a Testosterone cycle under their belt and have built up some tolerance to anabolic steroids.
This stack has the power to add 30-40lbs of weight gain to a user, accompanied by 50-70lbs of increased strength on compound lifts.
Some of the weight gained will be in the form of water, thus bloating and water retention are likely; with Dianabol having the aromatase enzyme active.
This cycle has the potential to cause gynecomastia from high levels of progesterone (Deca Durabolin) and estrogen (Dianabol). Thus, an AI (anti-aromatase inhibitor) can be utilized to combat the conversion of testosterone to estrogen, albeit at the expense of exacerbating blood pressure.
This cycle was perhaps the most common duo used in the golden era by the great, classic bodybuilders. Such a cycle produced exceptional levels of mass, without androgenic effects; enabling users to keep their hair intact and prevent male pattern baldness (androgenetic alopecia).
Deca Durabolin and Anadrol Cycle
Anadrol (oxymetholone) is a similar compound to Dianabol, being an oral steroid that possesses immense muscle-building and strength-enhancing effects.
The main benefit of stacking Anadrol with Deca Durabolin, is due to its androgenicity.
Anadrol can help to alleviate impotence associated with Deca Durabolin, due to higher nitric oxide production; improving blood flow to the penis.

The above cycle is suitable for advanced steroid users only, due to Anadrol’s harsh effects on the body; particularly cardiovascular and hepatic strain.
Anadrol ran by itself has the power to cause hypertension, due to its high mg dosage of 50-100mg per day. It also negatively affects hepatic lipase, an enzyme that can significantly reduce HDL cholesterol levels.
Increased risks of gynecomastia are of concern when taking the above cycle, due to Deca Durabolin increasing progesterone and Anadrol increasing estrogen levels.
An AI (aromatase inhibitor) will be ineffective for treating Anadrol’s estrogenic effects, as it does not aromatize, but instead directly stimulates the estrogen receptors.
SERMs such as Clomid or Nolvadex can inhibit estrogen activity from a receptor level, thus preventing gynecomastia from Anadrol. However, these SERMs can also increase progesterone (5), thus increasing nandrolone-induced gynecomastia.
Some steroid-users may try and prevent gynecomastia when running this cycle, by administering an aromatase inhibitor (AI) to lower progesterone (not estrogen); however, this can exacerbate cardiovascular strain due to lower levels of estrogen. Furthermore, Anadrol-induced gynecomastia remains a concern even when running an AI.
Testosterone suppression will be extreme post-cycle with this stack, requiring an aggressive PCT.
Dr. Michael Scally, an expert in hormone replacement therapy, has experienced extensive success implementing a trio of medications; accelerating the recovery of anabolic androgenic steroid-induced hypogonadism (ASIH).
These are:

Human chorionic gonadotropin (hCG)
Clomiphene (clomid)
Tamoxifen (nolvadex)

When these three medications were given to 19 men with shut down endogenous testosterone levels; after 45 days, 100% of them had normal serum testosterone readings.
Deca Durabolin and Testosterone Cycle
Testosterone is another potent anabolic steroid, typically taken to add large amounts of muscular hypertrophy (size) and strength in the off-season
However, testosterone can also be utilized as a cutting steroid, due to its strong androgenic properties having a stimulatory effect on lipolysis; resulting in decreased adipose tissue (enhanced fat loss).
Testosterone is regarded as one of the safest anabolic steroids, being FDA approved and prescribed to many men worldwide for the treatment of TRT (testosterone replacement therapy).
Testosterone and Deca Durabolin can be regarded as one of the mildest stacks a bodybuilder can utilize, in regards to side effects.
However, it remains a potent duo for enhancing body composition, with users experiencing 30 plus pounds of muscle gain and amazing improvements in strength.

This bulking cycle does not present a massive risk for hypertension; however, cholesterol changes are to be expected; causing mild increases in blood pressure. Deca Durabolin and Testosterone are two of the most cardiovascular-friendly steroids available.
Testosterone compliments Deca Durabolin exceptionally well, due to Testosterone’s androgenic nature reducing the sexual side effects of Deca Durabolin. However, unlike Anadrol, Testosterone does this without compromising health in other aspects (such as the liver).
This cycle is also better suited to someone trying to prevent gynecomastia, as an aromatase inhibitor (AI) can be taken, synergistically lowering estrogen and progesterone levels.
Anastrozole and letrozole are two popular AI medications taken by bodybuilders today.
Endogenous testosterone levels will decrease dramatically, requiring a PCT and some users experiencing: hair thinning, recession, or loss on the scalp due to testosterone raising DHT (dihydrotestosterone). This cycle is less hair-friendly compared to the Deca Durabolin/Dianabol stack.
Deca Durabolin Results (Before and After Pictures)

This user displays amazing improvements in muscle hypertrophy and thickness after completing a Deca Durabolin/Anadrol cycle.
In the before picture he had previously taken SARMs (selective androgen receptor modulators), therefore this wasn’t his first PED cycle.
This before and after transformation is typical of someone stacking Deca Durabolin with another powerful bulking steroid. Stretch marks can be seen on his right deltoid in the after photo, indicating the rapid anabolic effects of Anadrol/Deca.
Note: Deca-only cycles are unlikely to add this level of mass, with 20lbs of muscle being the more likely outcome (rather than 30-40lbs).
Deca Durabolin For Women
Deca Durabolin is sometimes taken by women when trying to bulk up and gain lean muscle tissue.
Although Deca Durabolin may not be the most optimal steroid for women (with Anavar being a more popular compound), research suggests Deca Durabolin is relatively safe from a virilization perspective.
Studies indicate that Deca Durabolin is generally well-tolerated by women when taken in dosages of 100mg (6), administered every other week for 12 weeks (thus translating as 50mg/week).
However, studies also suggest that Deca Durabolin is capable of causing masculinization in women, even in very small dosages, when taken long-term.
Such adverse effects occurred on a dose of 50mg, administered every 2-3 weeks. This translates as a dose of 13-25mg per week (7). Thus, if women were to take Deca Durabolin it would be wise to keep cycles short (preferably 8 weeks or less).
Deca Durabolin Cycle for Women

Note: Anadrol would be a more suitable bulking steroid for women, in terms of preventing virilization; with mega-doses failing to produce virilization, even when taken for excessive periods of time (8).
Anadrol also is a fast-acting compound that clears out of the body quickly, whereas Deca Durabolin is slow-acting with a half-life of 6 days; thus making it riskier for women who begin to experience masculinization symptoms. This is because even if they stop taking Deca Durabolin, it will remain in their system for up to 12 days.
FAQs
Deca Durabolin vs EQ (Equipoise)
Equipoise (Boldenone Undecylenate) is an injectable veterinary steroid, commonly given to horses to increase lean body weight.
EQ is a modified form of testosterone, like Deca Durabolin, with a double bond being introduced between carbons 1 and 2.
Bodybuilders often take equipoise as an alternative to Deca Durabolin, being a slightly more powerful and androgenic compound.
Equipoise is believed to be more estrogenic than Deca Durabolin, with EQ displaying 50% (half) of the estrogenic effects of Testosterone and Deca Durabolin just 20%.
The general consensus is: if EQ replaced Deca Durabolin in various steroid cycles, the end result would be very similar.
Trenbolone vs Deca Durabolin
Trenbolone and Deca Durabolin are both injectable bulking steroids, yet are very different in their pharmacology and effects.
Trenbolone is more anabolic than Deca Durabolin, reflected in its anabolic rating of 500 vs Deca Durabolin’s 125.
Thus, trenbolone will add more lean muscle than Deca Durabolin, however weight gain at the end of a cycle may be similar; due to Deca causing fluid retention and trenbolone enhancing fat loss.
Trenbolone is considered one of the most potent and harshest AAS, whereas Deca Durabolin is mild and FDA-approved (in medicine).
Trenbolone will cause considerably more cardiac hypertrophy (enlargement of the heart) and increase the risk of atherosclerotic plaque.
Trenbolone also is very androgenic and Deca Durabolin is not, thus hair recession/loss on the scalp, acne vulgaris and prostate enlargement are common with trenbolone (but rare with Deca Durabolin).
Thus, trenbolone will have a more dramatic effect on body composition; however, it will also come with more severe side effects, specifically — hypertension.
Summary: Deca Durabolin Pros and Cons
Pros:

Mild side effects
Effective mass-builder
High tolerance among women (during short-term use)
Promotes joint health

Cons:

Impotence
Delivery via injection (inconvenient for some users)
Suppressive to endogenous testosterone

Many are curious whether certain friends, family members or spouses are taking anabolic-androgenic steroids. However, due to legality issues, health concerns and social stigmas; many steroid-users do not want to disclose such details (even to loved ones).
However, they may not need them to admit to such, with there being numerous signs of steroid-use, that are observable from a person’s behaviour and appearance.
In this guide we reveal the top 15 ways to spot a steroid user, thus if someone ticks several of the boxes on this list, the chances are they are either: taking steroids, or have done so during their lifetime.
Note: this list does not guarantee 100% accuracy, which is only possible through random testing. 

15 Signs of Steroid-Use
1. Flushed Skin
Anabolic steroids cause LDL cholesterol levels to rise and HDL levels to plummet, causing hypertension to different degrees (depending on the compounds used).
One symptom of raised blood pressure is an increase in core body temperature.
When a person’s temperature rises, their skin can look flushed or take on a pink appearance.
This is a sign that someone is currently administering anabolic-androgenic steroids (AAS) on a cycle.
It is important to understand that some people naturally have a flushed appearance to their skin; however, if someone’s complexion has been altered; this can point to steroid use.
Note: There are other drugs and medications that can elevate systolic blood pressure, causing similar flushing, such as pre-workout supplements or stimulant-based fat burners.
2. Sudden Changes in Body Composition
If someone has suddenly blown up and gained 30lbs of muscle mass in the last few weeks, this is indicative of steroid use (particularly the use of bulking compounds).
Building muscle naturally is a very slow endeavor, that takes many years of hard work and discipline, in regards to training and nutrition.
If someone has built large amounts of muscle, whilst simultaneously getting leaner, this also indicates anabolic assistance.
This is because it is very difficult for natural bodybuilders to add muscle and burn fat simultaneously, due to a calorie surplus often needed to gain weight and a calorie deficit needed to lose weight.
Thus, you cannot be in a caloric surplus and deficit synchronously, which is why bodybuilders have two separate phases, known as bulking and cutting.
However, anabolic steroids, such as Anavar, Trenbolone, Testosterone or Winstrol, can make it very possible to add muscle and strip away fat concurrently.
However, it is important to note that when a person first starts lifting weights, it is normal for them to build significant amounts of muscle (20-30lbs), whilst simultaneously burning fat stores, as their body responds to this new stimulus.
Dramatic results among novice weight lifers are known as ‘newbie gains’ and mostly occur during the first couple of months of regular training.
If someone suddenly gains 20-30lbs of muscle but has been lifting weights for an extensive period of time; this is a sign of an enhanced athlete.
The most effective way to know if someone is taking steroids is to observe their ‘gains timeline’.
This involves compiling several pictures of the person throughout their life, to see when certain growth spurts occurred.
If someone experienced dramatic results when they first started lifting, plateaued afterward, then had another conspicuous growth spurt five years later; this points to steroid use.
However, if someone was exceptionally muscular during puberty, then started lifting weights and gained 20 pounds of muscle; then remaining (approximately) the same size afterward. This is indicative of strong genetic structure and not anabolic steroid use.
3. Roid Rage
Anabolic steroids increase serum testosterone levels to exceptionally high levels (exogenously).
Consequently, aggression is likely to increase, resulting in bursts of anger in some individuals.
The degree of anger is likely to depend on the person, however most steroid-users will notice themselves becoming less patient and more irritable with the people around them.
Unfortunately, this side effect may lead to hypomania or manic episodes, negatively affecting spouses.
One study even found that steroid-users were twice as likely to commit a weapon-related crime (1).
4. Disproportionate Muscle Groups
Research suggests that steroid-users who participate in weight training build significantly more hypertrophy (size) and strength, compared to steroid-users who are sedentary (2).
Therefore, if someone were to take steroids and not train certain muscles (such as their quadriceps); this could result in a more disproportionate body; compared to a natural weight lifter training in the same fashion.
In short, steroids cause extreme hypertrophy in trained muscle cells. Therefore, it is easier to become disproportionate, if certain muscle groups don’t receive the same level of volume as others.
Note: Disproportionately sized muscles can occur in natural athletes; however, the potential for unevenness is considerably greater when utilizing anabolic-androgenic steroids.
5. Hair Loss (Male Pattern Baldness)
Steroid use often damages hair follicles on the scalp, resulting in genetically sensitive individuals experiencing MPB (male pattern baldness) or alopecia.
This side effect is particularly common in highly androgenic steroids, such as Trenbolone, Anadrol and Testosterone.
High levels of androgens in the body, significantly elevate DHT (dihydrotestosterone) levels, causing hair follicle shrinkage. This can lead to thinning, recession or loss of hair on the scalp, whilst thickening and accelerating hair growth on the body.
Note: This side effect is largely influenced by a person’s genetics, thus a person could take steroids and not notice much hair loss (especially if androgenic steroids are avoided). However, on average, steroids will expedite the hair loss process for many individuals, causing increased recession or thinning.
6. Exceptional Deltoid/Trapezius Development
The deltoids (shoulders) and trapezius muscles often experience the most growth when taking anabolic steroids.
This is because a higher number of androgen receptors are found in these muscles, causing them to be more susceptible to increased hypertrophy (size), when under the influence of androgenic compounds.
3D boulder shoulders and cobra-looking traps are often unattainable for a natural bodybuilder.
However, someone may be taking anabolic steroids and not have exceptionally well-developed deltoids or trapezius muscles; due to the specific compounds used.
For example, Arnold Schwarzenegger never displayed colossal hypertrophy in the deltoid/trapezius region; however, he was known to be taking less androgenic steroids, such as Dianabol (Methandrostenolone) and Deca Durabolin (Nandrolone).
The only logical explanation for why a natural bodybuilder would have excessively large deltoids/trapezius muscles is if their training reflected high volume for such muscles groups, in comparison to the rest of their body. 
7. Acne
Acne vulgaris or seborrhea (oily skin) can be visual signs of steroid use and are particularly common when androgenic compounds are used (examples: Trenbolone, Testosterone, Anadrol).
Potent AAS can cause overactive sebaceous glands, stimulating excessive levels of sebum.
Sebum is a waxy matter, that in standard amounts acts as a healthy moisturizer to the hair and skin.
However, over secretion can result in blocked pores. In extreme cases, this can lead to cystic acne, where cysts the size of golf balls may form underneath the skin.
This side effect is more linked to genetics; however, if someone is known to have oily skin, this is likely to worsen when taking steroids. 
8. Difficulty Urinating
Androgenic steroids can cause benign prostatic hyperplasia (enlargement of the prostate gland).
This can lead to blocked urinary flow, making it more difficult for men to empty their bladder.
This side effect is what inspired Dr. John Bosley Ziegler to design a compound that would be more anabolic than Testosterone, yet less androgenic; as it was known that Soviet athletes were using catheters (consequent of their Testosterone use).
Dr. Ziegler succeeded in his mission, formulating Methandrostenolone, known today as Dianabol. 
9. Gynecomastia

Gynecomastia is essentially enlargement or swelling of breast tissue in men. This occurs due to hormone imbalance; specifically estrogen dominance.
Many anabolic steroids have the aromatase enzyme present, which is responsible for converting testosterone into estrogen (the female sex hormone).
Consequently, a man may develop puffy nipples or female-looking breasts, requiring an anti-estrogen medication to reduce swelling, or surgery to remove glandular tissue and excess fat.
Bodybuilders often have protocols in place to prevent gynecomastia from occurring, such as running an AI (aromatase inhibitor), being Anastrozole (Arimidex) or Letrozole (Femara). Such medications prevent the conversion from testosterone to estrogen.
Also SERMs (selective estrogen receptor modulators) may be taken, such as Tamoxifen (Nolvadex) during a cycle, to block estrogen-like effects directly in the breast tissue receptors. SERMs are more optimal than taking AI’s, in relation to cardiovascular health, with SERMs having no adverse effects on blood lipids (3).
Steroid-users may also opt for less estrogenic steroids, in an attempt to avoid this visually unpleasant side effect.
Some examples of highly estrogenic steroids are Anadrol, Dianabol and Testosterone.
Some examples of anabolic steroids that fail to aromatize (and convert to estrogen) are Trenbolone, Anavar and Winstrol.
10. Water Retention/Bloating
Further implications of estrogenic steroids are water retention and bloating.
Estrogen increases osmotic sensitivity (4) and sodium retention, due to fluctuations in aldosterone (5); thus causing extracellular fluid to accumulate (outside the muscle cells).
This contributes to a decrease in muscle tone and higher incidents of bloating in users, with the extent of which depending on the dosage.
Many weight lifters and bodybuilders administer significantly higher dosages of AAS today, compared to those in previous generations, resulting in bigger waistlines and puffier physiques.
Steroid-induced water retention can also cause extremely full and even 3D-looking muscles. This is due to increased glycogen uptake inside the muscle cells, causing exceptional thickness and a constant pumped look.
11. Increased Visceral Body Fat

Steroid-users can be lean, yet have a bloated or fat-looking stomach.
This isn’t always attributed to water retention, but instead higher levels of visceral fat (VF).
Visceral fat is adipose tissue that accumulates around vital organs, such as the liver and intestines. This type of fat isn’t visible to the naked eye (unlike subcutaneous fat); however, it can cause the abdomen to have a protruding appearance.
High levels of VF are associated with increased health risks, such as cardiovascular disease and type II diabetes.
One study measured the body fat percentage of ex-steroid users and found them to have less fat mass (on average), compared to non-steroid-users (3).
However, the steroid-user group had higher levels of visceral fat, compared to males who had never taken AAS.
This increase in visceral fat is due to impaired insulin sensitivity, caused by anabolic steroids, which can prolong for several years after steroid cessation.
In contrast, natural bodybuilders can display very tiny waists at low levels of body fat, with no distension or bloating (from the midsection).
Although many anabolic steroids increase visceral fat, there is evidence to suggest certain steroids may reduce VF; at least in the case of Anavar (Oxandrolone).
In one study they found Anavar-use not only resulted in less subcutaneous fat, but also less visceral fat; compared to Testosterone (4). This may be linked to Anavar improving insulin sensitivity, rather than worsening it (5,6).
12. Virilization in Women

If women use highly androgenic steroids, they may experience virilization effects, otherwise known as masculinization.
Such adverse effects include:

Irregular menstrual cycles
Clitoral enlargement
Breast reduction
Hair growth (on the body)
Hair loss (on the scalp)
More pronounced jawline
Adam’s apple (laryngeal prominence)

There are however some female-friendly steroids that have a low virilization risk, such as Anavar and Primobolan. However, if high dosages are utilized or cycles become excessive, the above effects are still possible.
13. Erectile Dysfunction
Erection quality is likely to increase when taking steroids, due to large spikes in exogenous testosterone and nitric oxide production. However, as a steroid cycle reaches its latter stages and eventually ceases; ED is a common side effect, due to the shutting down of endogenous (natural) testosterone.
This can even occur in the initial stages of a cycle with some compounds, such as Deca Durabolin (nandrolone).
Nandrolone-induced erectile dysfunction, or ‘Deca dick’, as referred to in the bodybuilding community, is caused by the elevation of prolactin levels. High amounts of prolactin can have a negative effect on libido and sexual desire/enjoyment (7).
14. Increased Alpha Male Behaviour
High testosterone levels are associated with alpha male behaviour, thus when someone takes steroids they are more likely to express dominance, confidence and assertiveness.
This may be more easily observable in introverted or shy individuals, who may now come out of their shells.
Alternatively, individuals who are already confident may become more so; due to even higher levels of serum testosterone.
However, this effect may only be short-lived, as testosterone levels crash post-cycle; leaving a person with low T levels for several weeks or months following.
Such fluctuations in this male hormone can contribute to steroid addiction/dependence; as much from a psychological perspective, than a physiological one.
Testosterone plays a crucial role in well-being, thus steroid-users often report feeling euphoria, caused by high levels of dopamine.
Thus, steroid abuse (albeit related to physical fitness), is similar to other drug-use; in the sense that it triggers ‘reward’ neurotransmitters in the brain.
15. Dry Looking Muscles

Many steroids contribute to fluid retention; however, some AAS have diuretic effects, giving a dry look to the muscles; with veins and muscle striations becoming more visible.
Winstrol and Anavar are two steroids that expel extracellular fluid, resulting in a vast and rapid improvement in muscle definition.
Such low levels of water retention, can look artificial and almost as if a bodybuilder has been photoshopped.
Thus, depending on what steroid is used, individuals may experience a smooth/bloated appearance, or an overly dry/ripped one. 
Summary
Research suggests 3-4 million people use anabolic-androgenic steroids in America (8), with over 1 million people in the UK also taking them regularly for cosmetic purposes (9).
It is important to remember that if someone has big muscles, or is in good shape, it doesn’t necessarily mean they are taking steroids (or have taken them). Genetics is arguably a more overriding factor in affecting body composition, than taking AAS.
The various signs of steroid use listed in this article are a more accurate method in identifying potential steroid-users, than merely judging by the size of someone’s muscles.
However, there certainly will be a threshold in regards to the maximum amount of lean muscle a human can carry (without the use of anabolic steroids).

Disclaimer: The following article is for educational purposes only and NOT to promote the use of illegal steroids. If you have any questions or concerns, Dr. Touliatos is currently available for consultations.

Superdrol is the brand name for Methasterone, an oral anabolic steroid that was first described in 1956 by Syntex; the same pharmaceutical company that formulated Anadrol 50 and Masteron.
Syntex was attempting to find an azo compound with anti-tumor properties (1).
In late 2004, Superdrol was sold by Designer Supplements LLC via the internet (2).
Superdrol was incorrectly marketed and sold as a prohormone, in an attempt to bypass the Steroids Control Act of 1990.
Superdrol developed somewhat of a cult following due to its potent effects; able to build significant amounts of lean muscle, without any water retention.
SUPERdrol was a fitting name for such a powerful over-the-counter product.
Matt Cahill, the owner of Designer Supplements, claimed the first batch of Superdrol sold out within 15 minutes of being available online; selling 2,200 bottles in total.
Designer Supplements later agreed to a licensing agreement with Anabolic Resources, allowing them to sell Superdrol in return for a lump sum, plus royalties (totaling around $182,000).
However, in 2006 the FDA issued a warning, stating that Anabolic Resources‘ Superdrol contained an unapproved steroid compound (3), being Methasterone. Consequently, it was pulled from the market.

Superdrol Benefits
There is some debate as to how effective Superdrol really is.
This is due to it being sold on the black market, where products are often counterfeited or diluted.
However, bodybuilders able to get real Mesthasterone, often describe it as one of the most potent anabolic steroids on the market (alongside Trenbolone).
Lean Muscle & Strength
Superdrol has the power to add 15-20lbs of lean muscle via a cycle, as well as enhancing strength to record levels.
Generally, bodybuilders won’t gain more than 20lbs on Superdrol, because those who take it are already advanced steroid users, who’ve used many compounds before.
Thus, making huge gains with a new steroid is unrealistic, as most muscle and strength gains are experienced during the first few steroid cycle(s).
However, due to Superdrol’s sheer power, it is capable of taking a user’s gains to the next level (including advanced steroid users).
Bodybuilders and powerlifters have suffered serious injuries when taking Superdrol, due to strength levels increasing excessively in a short period of time. One user ripped his abdominal wall and developed a hernia whilst performing heavy tricep pushdowns on Superdrol; later needing emergency surgery (4).
Thus, it is possible to get too strong too fast on Superdrol. Therefore, we encourage users to use caution and not lift as heavy as possible, reducing the likelihood of injury.
No Water Retention
Superdrol doesn’t aromatize and convert to estrogen, thus virtually all weight gain will be in the form of lean muscle.
Therefore, a lean physique can continue looking aesthetic and ripped; contrary to other bulking steroids which often compromise muscle definition (with extracellular fluid accumulating).
No Risk of Gyno
Superdrol does not cause high levels of estrogen or progesterone, thus gynecomastia is not an issue with this oral.
Huge Pumps
Superdrol is known for its incredible glycogen uptake inside the muscle cells, causing very full and pumped muscles. Pumps in the gym are likely to be intense, whilst a constant semi-pump is typically maintained outside of the gym.
Superdrol is arguably the most powerful steroid for pumps, which may be a downside to those susceptible of painful lower back pumps (when performing heavy deadlifts).

Legal Steroid Alternatives That Work

“There is evidence, if you could use these (steroid alternatives) they would be much better than using anabolic steroids”.
Several of the herbs and amino acids, mentioned by Dr. Thomas O’Connor, are present in Crazy Bulk’s legal steroid alternatives.
CB’s products are backed with clinical research and are safe for men and women to use. You can view their product range (and receive 20% off) by clicking the link below.

Superdrol Side Effects
Note: Superdrol is not suitable for beginners due to its high toxicity.
Don Catlin, founder of UCLA Olympic Lab and member of ICC medical commission said:
“Superdrol is one of the most disturbing compounds that ever came along. Not only was it potent, the toxic effects appeared faster than other steroids”.
Cardiovascular
Superdrol has a dramatic effect on HDL/LDL cholesterol levels, causing a sharp elevation in blood pressure via vasoconstriction.
Superdrol should be regarded as one of the most harmful steroids for blood pressure, due to the following reasons:
Superdrol is an oral steroid – thus it stimulates hepatic lipase enzyme in the liver, causing great shifts in cholesterol.
Superdrol doesn’t convert to estrogen – Many bodybuilders view this as a positive because it means they won’t experience water retention or gyno. However, on the flip side, high estrogen has advantages in regards to controlling cholesterol (with higher levels combating hypertension).
Liver Toxicity
The main issue with Superdrol is liver toxicity, with it being a C-17 alpha alkylated steroid.
Also, Superdrol is methylated, thus the compound is effectively broken down twice; which is like dropping a bomb on the liver.
Kevin Smith, the ex-president of Anabolic Resources, admitted: “We started getting calls of liver problems”.
One user, Jareem Gunter, experienced liver failure after just weeks of using Superdrol. Doctors warned that he would need a liver transplant or he would die.
In one study, a man developed jaundice from taking 2 tablets of Superdrol a day for 50 days (5).
Superdrol is dosed at 10mg per tablet, thus he took 20mg per day for 50 days.
This is a lengthy cycle for any toxic oral steroid. The most worrying factor about this man’s experience is that he didn’t have any pre-existing health problems before taking Superdrol.
Thus, if someone were to take Superdrol it would be wise to supplement with 500mg of TUDCA per day, throughout the cycle, offering maximum protection to the liver. However, avoiding Superdrol altogether would be the safest option.
Androgenic
Superdrol has an androgenic rating of just 20, which is very low for such a potent muscle-builder. However, this score doesn’t translate in real life; with Superdrol’s effects known to be very androgenic in practice.
Thus, male pattern baldness, prostate enlargement and acne are all possible interactions.
Women will almost certainly experience virilization effects should they choose to use Superdrol.
Testosterone Suppression
Superdrol has a powerful, negative effect on the hypothalamus-pituitary-gonad axis, effectively causing ASIH (anabolic steroid-induced hypogonadism).
This essentially is the shutting down of natural testosterone levels, which will take several weeks, or more likely months, to recover back to normal levels.
An aggressive PCT should be utilized, in an attempt to restore normal endogenous testosterone production back to previous levels.
Until testosterone levels bounce back, users should refrain from using any other steroids which will exacerbate this shutting down effect.
Dr. Thomas O’Connor has reported that several of his patients have suffered from “severe depression” from using Superdrol (6). This may be attributed to its potency and dramatic lowering effect of endogenous testosterone; which is crucial for well-being.
Superdrol Cycle
Bodybuilders typically take anywhere from 10-20mg of Superdrol a day, lasting from 4-6 weeks. Some advanced bodybuilders go as high as 30 or 40mg, but this is really playing Russian roulette with your health.
Because of its devastating effects on the liver, a 4-week Superdrol cycle is sufficient for most bodybuilders.

Superdrol dosages should be spaced out throughout the day, as Superdrol is very fast-acting. Thus, to keep steady levels of serum testosterone users may take 10mg in the morning and 10mg in the evening.
Taking a full day’s dose in one sitting is likely to cause fewer gains and harsher side effects, as testosterone levels will become less stable (with peaks and troughs).
Important: Strictly no alcohol or supplements/medications that compromise the liver should be administered whilst taking Superdrol.
500mg/day of TUDCA should be taken to decrease liver damage, as well as 4g/day of fish oil to minimize large spikes in blood pressure.
Superdrol should not be stacked with other steroids, due to its high toxicity. Anadrol, Winstrol, Dianabol and other hepatotoxic steroids should definitely be avoided, due to their hepatotoxic effects.
Superdrol Review
Below is a video review from Dan in Thailand, describing how Superdrol affected him, and his results.
[embedded content]
Dan has taken many steroids before and was diligent with his Superdrol cycle, keeping the dose to 20mg/day and not cycling it for more than 3 weeks. However, this was still enough time to see a dramatic effect on his physique and in the gym — gaining 20-3olbs on his lifts.
Superdrol Before & After Pictures
These pictures were found via bodybuilding forums from users who have taken Anadrol.

This user cycled Superdrol for 4 weeks, taking 30mg/day for week 1, and 40mg/day for weeks 2-4.
He reported gaining 22lbs whilst bulking and eating in a calorie surplus.
His body fat percentage has only increased slightly.
These are impressive gains, considering a steroid user will struggle to grow much after his/her first few cycles. Superdrol is rarely ever taken by a beginner, yet still has the power to take muscular size and strength to new levels.

This user took Superdrol for a month and mentioned he was cutting on it.
As you can see his back thickness has improved significantly, despite eating in a calorie deficit.
Eating maintenance or surplus calories is optimal for maximum muscle/strength gains on Superdrol; however, his results were impressive. 
The user mentioned gaining 10lbs, which perhaps may be closer to 15lbs of lean muscle when accounting for a month’s worth of fat loss.
He also mentioned making the majority of his gains during the 3rd and 4th weeks of his cycle.
FAQ
Superdrol vs Anadrol
Superdrol and Anadrol are somewhat similar, with both of them being very powerful and toxic oral steroids.
Superdrol mg per mg is a lot stronger, hence how only 10-20mg is needed for great results. In comparison, a typical Anadrol dose is 50-100mg.
The main difference between the two steroids is that Superdrol is not estrogenic, thus you won’t have any gyno or water retention concerns. Whereas on Anadrol, water retention is almost certain and gynecomastia is possible.
Both of these steroids should only be taken by advanced bodybuilders, due to their drastic effects on the liver and heart. They should never be taken together.
Superdrol vs Dianabol
Superdrol and Dianabol are also fairly similar, with both being powerful muscle and strength builders. They are also both orals.
However, the main difference between Superdrol and Dianabol is estrogenic and androgenic side effects.
Dianabol aromatizes, thus comes with water retention and potentially gynecomastia (whereas Superdrol doesn’t).
Dianabol is not particularly androgenic, whereas Superdrol is in practice.
Thus, Superdrol will likely result in more incidents of hair loss, acne and prostate enlargement.
Can You Use Superdrol as a First Cycle?
Beginners should strictly avoid Superdrol due to its high toxicity. It should be the last compound a novice should think of taking.
There’s also no reason why a beginner would want to take Superdrol, as a testosterone cycle is much safer; and very capable of producing exceptional muscle and strength gains.
Taking Superdrol as a first cycle would be the equivalent of diving straight into the deep end when learning how to swim.
However, a beginner may be able to take Superdrol and remain unscathed if they ran a very low dose; such as 5mg per day. Such low doses are not commonly taken among bodybuilders, thus it’s uncertain if beginners would experience as positive of results on 5mg/day of Superdrol; compared to 350mg/week of testosterone.
Can You Use Superdrol for Cutting?
Superdrol can be an effective steroid when cutting. Its effects are androgenic in practice, thus when combined with a calorie deficit, users can expect enhanced fat loss.
Its ability to cause huge and full muscles (due to additional glycogen), is why some bodybuilders take it briefly before a contest.
However, a question users should ask is:
Is taking Superdrol for several weeks optimal when cutting?
The answer most likely is no.
Users’ results when cutting will largely be dictated by their diet and workouts. Powerful steroids may create a dryer appearance and speed up fat loss somewhat; however, the results are unlikely to be worth it for the strain Superdrol will place on the body.
A wiser compound to utilize when cutting would be Anavar, as its side effects are very mild compared to Superdrol. Also, Anavar is very capable of stripping fat and adding lean mass when in a calorie deficit.
Summary: Pros and Cons
Superdrol is one of the most powerful anabolic steroids available, thus its effects on muscle mass and strength are immense.
It is perhaps the best steroid for transforming a person’s physique quickly, with a short half-life (8-12 hours). Thus, results can be experienced in the early stages of a cycle.
The main drawback to Superdrol is its highly toxic nature, especially on the liver and heart.
It is one of the highest-risk steroids a bodybuilder can take, thus extreme caution should be used if someone were to use this compound.
Caution: It is generally a bad idea to stack Superdrol with other compounds, conservative doses should be taken and cycles should be kept short.

Novice weight lifters sometimes ask, “what are the best steroid cycles?”.
The correct answer to this depends on what someone hopes to achieve from a steroid cycle.
For example, if someone wanted to predominantly burn fat, they would take a drastically different cycle to someone who wanted to bulk up.
Furthermore, the best steroid cycle for a male may be completely different from an optimal cycle for a female; due to women wanting to avoid compounds that cause virilization.
In this guide, we will detail various steroid cycles; tailored for beginners, advanced users and those looking to bulk or cut.

Beginner Steroid Cycles
A person’s best steroid cycle is almost always their first steroid cycle.
This is because their body has not had a chance to build up any tolerance to anabolic steroids, thus resulting in rapid and dramatic changes in body composition.
However, a first cycle equally can be the most damaging or destructive cycle, as the body hasn’t had a chance to adapt to the compound.
Therefore, the best steroid for beginners is one that has mild side effects; yet is powerful enough to build significant amounts of muscle.
Note: Stacking steroids together is not a protocol generally adopted by beginners, as combining multiple compounds together often yields more severe side effects.
Testosterone Cycle
A Testosterone-only cycle is the staple protocol for many beginner weight lifters.
This is due to Testosterone producing significant muscle and strength gains, yet only causing mild side effects.
Thus, Testosterone is regarded to have one of the greatest risk/reward ratios, compared to other anabolics.
In terms of results, a cautiously dosed Testosterone cycle can add 20lbs+ of lean mass to beginners. Testosterone will also cause some fat loss, due to its androgenic nature. 
Muscular strength can also increase by 50lbs or more on various compound exercises, such as squats, deadlifts and bench press.
Unfortunately, Testosterone isn’t the most convenient anabolic steroid for administration, with it being predominantly injectable. However, this method of entry means it can bypass the liver (unlike c-17 alpha-alkylated steroids), thus entering the bloodstream immediately. Consequently, Testosterone causes little to no hepatotoxic effects.
Note: Testosterone is available in oral form (known as Undecanoate or Andriol); however, this is less commonly used by bodybuilders due to its high market price.

The above cycle is commonly used by novices looking to add substantial amounts of muscle and strength. Testosterone Cypionate or Enanthate are commonly used among beginners, due to such esters not requiring overly frequent injections.
Also, the injection itself is typically less troublesome with Cypionate and Enanthate, in comparison to other variations of Testosterone.
Testosterone Side Effects
Testosterone is androgenic in nature; thus inflammation of the prostate, acne vulgaris and male pattern baldness are possible.
Testosterone will also skew HDL and LDL cholesterol ratios, causing possible hypertension. However, this negative effect on blood pressure is mild compared to harsher AAS; with testosterone perhaps being the most cardiovascular-friendly steroid.
Water retention is also probable, due to Testosterone having the aromatase enzyme present.
Therefore, when exogenous Testosterone converts to estrogen, fluid can accumulate; causing bloating and puffy muscles. It also has the potential to cause gynecomastia and thus estrogen may need to be controlled to avoid female breast tissue forming in the pectoral region.
Testosterone also causes hypogonadism i.e. a significant decline in natural testosterone production; caused by the pituitary gland signaling to the testes. This process occurs due to excessive amounts of exogenous Testosterone present in the bloodstream, and thus the body trying to maintain homeostasis.
Anavar Cycle
Anavar (Oxandrolone) is classed as a cutting steroid in the bodybuilding community, often being utilized in competition prep.
It has anabolic effects in regards to muscle-building; however, such properties are only moderate compared to bulking steroids.
Instead, Anavar is primarily coveted due to its potent fat-burning properties, in addition to its ability to shed water, increasing vascularity and muscle tone.
Anavar’s ability to add lean muscle and strength, whilst simultaneously stripping fat, makes it popular among beginners. It is also an oral steroid, thus no injections are required.
Anavar is also suitable for women, with it rarely causing virilization in low to moderate doses.
Beginners can expect to gain 15lbs of lean muscle, whilst significantly reducing their body fat percentage with Anavar. 

The above cycle is dosed for a male beginner. Women may take 10mg/day for 4 weeks; however, anything higher than this may cause masculinization effects.

Legal Anavar Alternative

Anvarol is our #1 rated legal Anavar product. It replicates the fat-burning and muscle-building effects of Anavar, but without any unwanted side effects.

It is FDA-approved and can be purchased online without a prescription.

Anvarol is best suited for men or women who want to reduce their body fat percentage, whilst simultaneously increasing muscle tone and building lean muscle.

Anavar Side Effects
Anavar is a c-17 alpha-alkylated oral steroid, thus it is processed by the liver upon absorption into the bloodstream.
However, Anavar’s hepatic effects are relatively mild compared to other oral steroids; therefore this side effect isn’t typically worrisome for bodybuilders.
Anavar will alter a user’s cholesterol profile, causing imbalances in HDL/LDL levels. This can cause hypertension; however, BP is unlikely to rise to excessively high levels.
Anavar’s cardiovascular strain is thought to be slightly more than Testosterone. This may be due to Anavar not converting to estrogen, plus being oral; thus stimulating hepatic lipase in the liver.
Anavar will also cause testosterone suppression; however, serum levels often peak back to normal levels within several weeks. This recovery process post-cycle is relatively short with Anavar, due to testosterone production not being completely shut down.
Bulking Steroid Cycles

Bulking cycles are utilized by bodybuilders seeking immense increases in muscle hypertrophy (size).
Many of these cycles are harsh on the body and thus only suitable for intermediates and advanced users.
The only exception to this rule is a Testosterone-only cycle, which is considered a relatively safe bulking protocol. 
Dianabol Cycle
Dianabol is the famous oral steroid thought to be used by the ‘Austrian Oak’, aka Arnold Schwarzenegger; helping him to become a formidable force on the Mr. Olympia stage.
Dianabol was formulated by Dr. John Bosley Ziegler, with the purpose of synthesizing a compound more anabolic than Testosterone, yet less androgenic.
Thus, Dianabol will produce similar (if not slightly superior) results to Testosterone; in regards to muscular strength and size. However, it does not mimic the androgenic effects of Testosterone, thus incidents of prostate enlargement, male pattern baldness or acne are less common.
Dianabol is sometimes taken by beginners; however, this is not recommended due to its harsh cardiovascular and hepatic effects. Thus, it is more suited for intermediates who have already taken a milder steroid previously, such as Testosterone.
Dianabol has the capacity to add 25-30lbs of lean mass in a single cycle. Strength will also reach new heights, with Dbol being regarded as one of the best steroids for raw power.

Dianabol Side Effects
Dianabol is a toxic oral steroid, thus it has a detrimental effect on AST and ALT liver values.
Thus, a liver support supplement such as TUDCA is often taken to reduce such strain.
Dianabol aromatizes and thus has high estrogenic activity. Consequently, water retention and gynecomastia are possible side effects from high levels of the female hormone.
Dianabol will have a particularly negative effect on cholesterol, potentially causing atherosclerosis (hardening of the arteries). Water retention and stimulation of the hepatic lipase enzyme in the liver are the main culprits for such cardiovascular stress on Dianabol.
Dianabol will also shut down testosterone levels, requiring an effective post-cycle therapy treatment to resurrect natural endogenous production.

Anadrol Cycle
Anadrol’s benefits largely mimic Dianabol’s; producing colossal increases in muscle hypertrophy and strength.
Anadrol is regarded as one of the most powerful bulking steroids available; typically producing slightly more weight accumulation, compared to Dianabol.
It is also an oral steroid, making it a preferable compound for those looking to avoid needles.
A first-time Anadrol cycle is likely to cause weight gain of 30+ pounds.

Advanced steroid users may also take dosages reaching as high as 100mg/day.
Anadrol Side Effects
Anadrol is not suitable for beginners, with it being one of the most toxic steroids available; causing large fluctuations in blood pressure and liver enzymes.
Anadrol is among the harshest steroids on the cardiovascular system; as well as being one of the most devastating AAS on the liver. Extreme caution must be used with this anabolic, particularly for users who regularly drink alcohol or have experienced high blood pressure in the past.
Anadrol is also a wet compound, causing noticeable amounts of extracellular fluid retention, that may temporarily obscure muscle definition; making it a common off-season drug.
Anadrol is also estrogenic; however, this is not due to the aromatase enzyme being present, but instead, direct stimulation of the estrogen receptors.
Therefore, a SERM (Selective estrogen receptor modulator) may be taken to reduce the chances of gynecomastia forming; as opposed to taking an AI (aromatase inhibitor).
Androgenic side effects are also common on Anadrol, despite its low androgenic rating of 45.
Therefore, male pattern baldness, seborrhoea (oily skin), acne vulgaris or/and benign prostatic hyperplasia (BPH) may occur.
Anadrol will shut testosterone levels down, requiring a well-thought-out PCT to restore normal testosterone function. Failure to implement an effective post cycle therapy, may result in low testosterone levels for several months, or permanently (if abused).
Trenbolone Cycle
Trenbolone is a very unique bulking compound, as it does not convert to estrogen; and thus causes weight gain that is virtually 100% lean muscle tissue.
If bodybuilders could choose one steroid to transform their bodies as quickly as possible, many of them would choose Trenbolone.
Trenbolone doesn’t cause any water retention, creating a very dry and ripped physique; despite being used primarily as a mass-building compound.
Therefore, the weight gain on Trenbolone won’t compete with Dianabol or Anadrol, however strictly in terms of its ability to build muscle tissue; it is equally as powerful. One difference is — when users come off Trenbolone, they often maintain their weight; whereas on Dianabol or Anadrol they commonly experience water loss.
However, Trenbolone doesn’t just add muscle; it also burns fat fast, due to its high androgenicity causing atrophy of adipose tissue. This has resulted in Trenbolone also being utilized as a cutting steroid, enabling bodybuilders to accelerate fat loss, whilst retaining (or even building) muscle on fewer calories.

Trenbolone Side Effects
Trenbolone is one of the harshest steroids on the market, unsurprisingly, as it produces remarkable results in its users.
Trenbolone is an injectable steroid, therefore like Testosterone, it doesn’t pose any major risks to the liver.
However, it will cause huge surges in exogenous Testosterone, that fail to convert into estrogen; causing vast fluctuations in cholesterol and blood pressure.
Trenbolone will also shut down endogenous testosterone levels aggressively, causing male hypogonadism.
Incidents of acne vulgaris or high due to excessive stimulation of the sebaceous glands. Hair follicle loss is also likely on Trenbolone versus other anabolic steroids, due to it causing DHT (dihydrotestosterone) levels to rise exponentially. To put Trenbolone’s androgenicity into perspective, its androgen rating is 500 (5x higher than Testosterone).
Trenbolone is also known to have a stimulating effect on the central nervous system, causing thermogenesis (increased body temperature). This can result in adverse effects such as insomnia, anxiety, restlessness, increased sweating and even paranoia in sensitive users.

Legal Steroid Alternatives That Work

“There is evidence, if you could use these (steroid alternatives) they would be much better than using anabolic steroids”.
Several of the herbs and amino acids, mentioned by Dr. Thomas O’Connor, are present in Crazy Bulk’s legal steroid alternatives.
CB’s products are backed with clinical research and are safe for men and women to use. You can view their product range (and receive 20% off) by clicking the link below.

Deca Durabolin Cycle
Deca Durabolin is another effective bulking steroid; however, it is best utilized in a stack due to its low androgenicity (usually cycled alongside Dianabol, Testosterone or Anadrol).
Deca Durabolin increases nitrogen retention uptake in the muscle cells, and enhances protein synthesis.
Deca Durabolin also causes exceptional muscle fullness, successfully shuttling more intracellular water inside the muscles.
It is difficult to assess the power of Deca Durabolin individually, as it is almost always stacked with other potent steroids. However, when users remove Deca from a stack; they quickly notice a considerable difference.
Deca and Testosterone Cycle

In comparison to other bulking stacks, this combination of testosterone and Deca Durabolin will cause the least side effects. This cycle may be administered once a user is comfortable taking Testosterone alone.
Deca Durabolin and Dianabol Cycle

This duo was one of the most popular steroid cycles from the golden era, used by Arnold Schwarzenegger and other greats from the ’70s. This steroid cycle is suitable for an intermediate steroid user.
Deca Durabolin and Anadrol Cycle

The above cycle has relatively high dosages, which is reflective of it being utilized by an experienced steroid user (based on Anadrol’s high toxicity).
Deca Durabolin Side Effects
Deca Durabolin is an FDA-approved medication for muscle-wasting ailments, albeit illegal to use for bodybuilding purposes.
Its FDA approval is indicative of the drug’s mild nature, being regarded as one of the safest anabolic steroids on the market.
Blood pressure will rise, albeit subtly and more to the level of Anavar than other bulking compounds.
Liver stress is not a concern with Deca Durabolin, being a non-hepatotoxic injectable steroid.
Deca Durabolin is notorious for causing sexual side effects, such as erectile dysfunction (ED) in men. This is referred to in the bodybuilding community as ‘Deca dick’.
Cases of ED are caused by Deca Durabolin’s weak androgenic nature, combined with high prolactin levels.
When androgens in the body are low, nitric oxide levels can plummet; which are crucial for supplying blood flow to the penis.
Low nitric oxide levels can be counteracted by stacking Deca Durabolin with an androgenic steroid, such as Anadrol, Testosterone or Trenbolone.
Deca also causes high prolactin levels in the bloodstream, which can cause low libido in men. Bodybuilders can often reverse this effect by supplementing with Cabergoline, a dopamine receptor, that has an inhibitory effect on prolactin.
Testosterone suppression is almost certainly going to be dramatic with Deca Durabolin, thus ample time will be needed to recover post-cycle. During this period, a PCT should be utilized and users should refrain from taking any other steroids; until natural testosterone levels return back to normal.
Cutting Steroid Cycles

The main objective of a cutting cycle is to shred fat, whilst retaining muscle tissue.
Anavar and Trenbolone are very effective cutting cycles (that we have already documented above).
Below we will list other steroid cycles that enhance fat burning, whilst simultaneously promoting muscle gain.
Winstrol Cycle
Winstrol (Stanozolol) has a similar steroid profile to Anavar, building moderate amounts of muscle, whilst enabling users to burn significant amounts of fat.
Winstrol, like Anavar, doesn’t convert to estrogen and possesses diuretic qualities.
If a person is relatively lean, a Winstrol cycle has the power to get them into low single digits of body fat; in conjunction with intense workouts and a disciplined diet.
Winstrol is regarded by many bodybuilders as being slightly stronger than Anavar, in terms of its benefits and side effects.
Thus, users will build slightly more muscle, whilst experiencing harsher side effects. Therefore, Winstrol is not for beginners or the faint-hearted.

Winstrol Side Effects
Winstrol causes hefty shifts in cholesterol, thus users should expect a significant rise in blood pressure. This may also be visibly apparent, with the skin becoming flushed and taking on a pink colour.
Winstrol may also cause joint pain, due to the flushing of water out of the body; which acts as a cushion to the joints.
This ‘drying out’ effect (of the joints) is the opposite effect of Deca Durabolin and may not complement bodybuilders who enjoy lifting heavy.
Winstrol also decreases collagen production, increasing the risk of injury and accelerating the aging process.
Winstrol causes significant hepatotoxicity, thus cycles should be kept relatively short to avoid excessive damage to the liver. Winstrol should not be stacked with any other oral steroids, to prevent the onset of jaundice or liver cholestasis.
Testosterone levels will also become shut down, decreasing sperm quantity and quality. Avoid regular steroid cycles, containing potent AAS like Winstrol, to give the body enough time to recover; otherwise low testosterone or infertility may become a long-term reality.
Women should avoid Winstrol, as it is prone to causing masculinization (at least in moderate dosages).
Primobolan Cycle
Primobolan is a mild anabolic steroid, available in oral or injectable form.
It is very similar to Anavar, in regards to it producing few side effects; whilst promoting moderate amounts of muscle tissue and fat loss.
Primobolan will not replicate the rapid and impressive results of Winstrol or Trenbolone, but instead is a safer option for the more ‘health-conscious’ steroid user (if such a thing exists).
Primobolan was widely used during the golden era when dieting down for a show; however, more potent cutting compounds are used today among IFBB pros.
Primobolan may add up to 10lbs of muscle, whilst providing noticeable fat loss. Primobolan, like Anavar, is a female-friendly steroid unlikely to produce virilization effects.

The above cycle is tailored for men; however, many women can take 50-75mg/day without experiencing masculinization. 
Primobolan Side Effects
Primobolan will cause some testosterone suppression, albeit very mild compared to other AAS.
It will also cause a mild peak in blood pressure levels, which is manageable for most users (especially among those who perform regular cardio).
Primobolan is not a c-17 alpha-alkylated compound, thus despite being available in oral form; it does not provide high levels of stress to the liver.
Primobolan is also commonly stacked with Anavar and Testosterone for enhanced results. 
Clenbuterol Cycle
Clenbuterol isn’t a steroid, but instead a bronchodilator; prescribed in medicine to optimize breathing in asthma patients.
Due to Clenbuterol displaying anabolic effects (at least in research), it is sometimes incorrectly referred to as a cutting steroid.
Clenbuterol’s most potent effects however come in the form of fat loss and its potent metabolic effects on the metabolism.
Clenbuterol stimulates the nervous system, triggering lipolysis via the process of thermogenesis.
A user’s body core temperature increases for several weeks, resulting in their basil metabolic rate shooting up.
In this case, the body temperature can rise by 1 degree, although once the body eventually cools itself back down (in approximately 4-6 weeks); fat loss is inhibited. This is why some bodybuilders only choose to cycle Clenbuterol for short periods, being as little as 2 weeks on/2 weeks off.
As Clenbuterol doesn’t greatly affect hormone levels, women can also take it in the same dosages without any complications, such as affecting their femininity.

Clenbuterol Side Effects
Clenbuterol can elevate the heart rate to high levels, as well as causing cardiac hypertrophy. Thus, dosages should be increased gradually to assess how a person responds to this drug.
Anxiety, insomnia and depression are common complaints that can be attributed to over-stimulation of the nervous system and excess adrenaline output.
Any supplement used to reduce the heart rate, in a bid to prevent such side effects, may also reduce fat loss (as the thermogenic effect is reduced/lost).
Advanced Steroid Cycles
Note: These steroid cycles should only be attempted by experienced bodybuilders who are healthy and have built up a tolerance to AAS.
Any steroid cycle that contains Anadrol, Superdrol, Trenbolone or Winstrol in a stack, can be considered an advanced cycle, as these are potent steroids (even when taken alone).
Anadrol / Testosterone / Trenbolone Cycle

This is the most potent bulking cycle advanced users can administer.
It combines three of the most powerful mass-building steroids simultaneously, causing incredible results, in terms of raw strength and size.
This cycle is also a very desirable trio for powerlifters looking to set new PR’s (no matter what their experience level).
However, the side effects are going to be extreme, thus if someone were to implement this trio, it should be done very rarely.
We encourage our readers not to utilize such cycles, due to the long-term implications of such drugs. 
Winstrol / Proviron / Trenbolone Cycle

This is the most potent cutting steroid cycle a bodybuilder can take (suitable only for advanced users). Men may utilize such a stack in preparation for a bodybuilding competition, where exceptionally low levels of body fat are rewarded.
A cycle like this will cause users to see their body changing rapidly before their eyes, with diuretic, fat burning and muscle-building effects taking place simultaneously.
This cycle should only be utilized when a person is already lean and thus looking to get increasingly ripped. This cycle may not be appreciated by someone higher in body fat, as although it would stimulate considerable weight loss; the diuretic effects would be more difficult to gauge.

Anavar (Oxandrolone) is the most popular anabolic steroid among both sexes, with it being highly coveted by men and women.
Men use it to build significant amounts of lean muscle and burn fat, without experiencing harsh side effects (which are very common with other anabolic steroids).
Women use it for the same reasons; however, Anavar remains one of the few steroids on the market that females can take, without experiencing masculinization effects. Therefore, for non-competing females who simply want to get in better shape — Anavar is often the perfect steroid to take.
Where Do Bodybuilders Buy Anavar?
There are 2 main options today when it comes to finding Anavar for sale.
1) Buying it through the black market.
2) Ordering ‘Legal Anavar’.
Anavar technically is illegal to use without a medical prescription. Thus, men and women taking it to get ripped are not acting within the confines of the law (except for a few countries in the world such as Thailand).
Therefore, you cannot buy Anavar in a local store, but instead on the black market. Thus, bodybuilders generally know someone who can get them their stash. However, the risks in purchasing via this method are evident, with not only legal risks but also health and financial complications. For example, nothing is stopping dealers from spiking certain steroids they sell; as they aren’t regulated and sometimes even produced in their basement.
Secondly, many steroids on the black market are scams, meaning they aren’t the steroid that is labeled on the bottle. Therefore, finding a good dealer is a must and even then there is a legal risk of getting caught.
Legal anavar, known as Anvarol, is also popular among gym-goers who want the anabolic and fat burning effects of oxandrolone (but also want to stay within the law).
Anvarol is manufactured by a company called Crazy Bulk, which also produces other legal, steroid alternatives such as D-Bal (Dianabol), Testo-Max (Testosterone), Trenorol (Trenbolone) and more.
Their formulas are not exogenous testosterone; however, they are aimed to replicate the effects of steroids without causing damaging side effects. Thus, because they are chemically different from anabolic steroids, they are FDA-approved supplements and 100% safe and legal.
One of the main advantages of Anvarol (legal Anavar) vs Oxandrolone (illegal Anavar) is that Anvarol doesn’t suppress testosterone levels or increase cholesterol levels. Thus, no PCT is needed and there’s no crash in energy, well-being, or libido post-cycle.
Also with cholesterol levels not spiking, blood pressure levels will remain stable on Anvarol, which is good news for those who are susceptible to high BP (or with heart disease in their family).
Hair loss and acne are also other less common side effects that are still possible when taking Anavar. Such adverse effects do not occur when taking Anvarol (legal Anavar).
Women also don’t need to worry about turning into a man on Anvarol, with it posing significantly less risk than even Anavar.
Anavar For Sale on the Black Market 
Other problems when buying Anavar illegally are — women are more at risk of developing masculine side effects; such as a deeper voice, enlarged clitoris, breast reduction and hair growth.
This is because Anavar is often swapped for Dianabol by dodgy dealers. 
They do this due to Anavar typically being a very expensive steroid, costing as much as hundreds of dollars for a lengthy cycle. Thus, with the active ingredient being Dbol, they can save a lot of money on their costs; and users still experience exceptional gains. However, Dianabol is androgenic and thus women will notice a big difference in side effects.
When this is sneakily done, men will notice more bloating and water retention with exceptional muscle and strength gains. However, Anavar causes more mild gains in size, with significant fat loss and no water retention.
If readers are intent on buying Anavar from the black market, it’s crucial to test the substance with a kit before ingesting it. This way you will be able to detect whether it’s 100% pure Anavar.
Anavar Stacks 
Many people will buy Anavar and not stack it with any other steroid (especially women). 
Running single steroid cycles is one of the best ways to minimize side effects. 
However, male bodybuilders typically stack Anavar with testosterone or Winstrol for enhanced fat loss, strength and lean muscle mass.
The addition of Testosterone will result in significantly bigger muscle and strength gains, with test often being used as a bulking compound. However, natural testosterone suppression will be more dramatic post-cycle and blood pressure will rise to higher levels with this combination. 
Stacking Anavar with Winstrol will increase muscle gains to a moderate degree, whilst taking fat loss to new levels. Winstrol will help to create a dry and shredded look, being predominantly a cutting steroid like Anavar.
Women often do not generally stack other compounds with Anavar, to reduce the chances of virilization. It is the more serious female bodybuilders (who compete) who stack compounds such as Anadrol or Winstrol alongside Anavar. Such women don’t mind developing a more masculine appearance if it means they take home the winner’s trophy.
Clenbuterol can also be stacked with Anavar for rapid fat loss, which is common among bodybuilders preparing for a show to be as defined and ripped on stage as possible.
Crazy Bulk also has a Clenbuterol legal steroid, which is combined with Anvarol (Anavar), Winsol (Winstrol) and Testo-Max (Testosterone) in their popular cutting stack.
FAQ
Is Anavar Safe?
Anavar is safe enough for it to be FDA approved in medicine, being prescribed to men, women and children. However, this is under the doctor’s supervision. Risks start to increase when it’s bought illegally (when products are often tainted).
Anavar is one of the few steroids that beginners can take without harsh effects. It’s also an oral steroid, so no injections are needed (which requires knowledge regarding site location). However, Anavar is still classed as an anabolic steroid, so caution is needed.
Is Anavar Bad For the Liver?
Despite Anavar being an oral steroid, its risk in relation to the liver is relatively mild. Thus, when taken in moderate doses there should be no long-term complications with the liver. However, if someone has existing liver conditions, then they shouldn’t take Anavar. Also, liver damage is possible if someone were to take mega doses of Anavar, or excessive cycles (such as 12+ weeks).
Can Anavar Cause Gyno?
Anavar is very unlikely to cause gynecomastia (gyno) as it doesn’t aromatize. This means estrogen levels do not rise; the female hormone and the culprit for causing gyno.
Progesterone levels also will not rise on Anavar, which is another hormone that can cause estrogenic-like side effects. Thus, Anavar is one of the best steroids for avoiding gyno.
If you are looking for Anavar for sale — we recommend Anvarol, due to it being 100% legal, safe and FDA-approved.

Given the sensitive nature of this article topic, we’d like to clarify that no steroid can be considered 100% safe; especially when bought on the black market for cosmetic purposes.
Anabolic steroids are also illegal, thus unless utilized by a doctor in a strict medical setting; AAS have the potential to cause dangerous side effects to users.
However, certain steroids are safer than others, hence why several AAS are approved by the FDA in medicine (whilst others are not).
It’s worth noting that bodybuilders often consume significantly higher dosages of anabolic steroids, compared to in medical settings; thus increasing the risk of side effects.
Furthermore, bodybuilders often take steroids without having regular checkups with a medical doctor, which is a further risk.
However, below are the mildest and least destructive steroids a bodybuilder can take:

Testosterone
Anavar
Deca Durabolin

Legal Steroid Alternatives That Work

Testosterone
Testosterone is an FDA-approved injectable steroid, used to treat millions of men all over the world, who are deficient in natural testosterone.
This is known as testosterone replacement therapy or TRT.
Testosterone was included in the World Health Organization’s List of Essential Medicines, regarded as crucial for treating endocrine disorders (1).
In 2017, it was the 132nd most prescribed medication throughout the U.S (2); with over 5 million prescriptions (3).
From 2001 to 2011 testosterone prescriptions have tripled (4), indicating a current low testosterone epidemic.
In bodybuilding, testosterone is predominantly used in bulking cycles to add large amounts of muscle and strength; however, it’s also utilized in cutting cycles to retain muscle hypertrophy.
When injected correctly, it can be argued that testosterone is one of the safest steroids available.
Testosterone causes hefty gains in muscle size (20-30lbs) and remains one of the most popular steroids in bodybuilding; despite coming to market over 80 years ago.
If injected incorrectly, any steroid or medication can be dangerous (or fatal).
However, there is oral testosterone available (undecanoate) for those wanting to avoid needles. Oral testosterone is less commonly used in bodybuilding, compared to injectables, due to its higher market price.
Testosterone Side Effects
Testosterone poses little to no hepatic concern (liver stress), due to it being injectable and thus entering the bloodstream immediately; instead of the liver having to filter it.
Oral testosterone (undecanoate) is also safe for the liver, with it being absorbed via the intestinal lymphatic route; thus preventing hepatic strain. One study gave 2,800mg per week of testosterone undecanoate to male subjects for 21 days (5); yet none of them experienced any hepatotoxic stress, despite such an exceedingly large dose.
Blood Pressure
Testosterone is likely to increase blood pressure, due to a redistribution of HDL/LDL cholesterol levels. However, such cholesterol fluctuations are mild, compared to other anabolic steroids.
There are a couple of reasons why testosterone doesn’t negatively affect blood pressure significantly. Firstly, it converts to estrogen, with the female hormone having a positive effect on blood lipids.
Secondly, testosterone doesn’t pass through the liver, thus failing to stimulate hepatic lipase, an enzyme that can skew cholesterol levels in the wrong direction.
There is evidence oral testosterone may even improve cardiovascular health, when therapeutic doses are administered in overweight men (6). This however is likely to be correlative, with a reduction in fat mass likely being the culprit for such reductions in BP.
For most bodybuilders taking moderate to high dosages of testosterone, blood pressure will rise; with the severity depending on the dose and cycle duration.
In research, 280mg/week of testosterone enanthate had a very slight negative effect on HDL cholesterol, after 12 weeks (7).
300mg/week of testosterone (enanthate), when taken for 20 weeks, caused HDL levels to drop by just 13%.
Meanwhile, 600mg/week caused a reduction of 21%.
Note: Taking an AI (aromatase inhibitor) will further spike blood pressure, by inhibiting testosterone to estrogen conversion, thus further decreasing HDL levels.
Estrogenic Side Effects
Testosterone has the ability to cause gynecomastia and water retention, due to its estrogenic nature; however, a SERM (such as Nolvadex) significantly reduces the chances of gyno forming.
Incidents of gynecomastia are particularly rare when combining low doses of testosterone with a SERM.
Androgenic Side Effects
Androgenic side effects, such as hair loss on the scalp, prostate enlargement and acne are possible on testosterone.
Such side effects inspired Dr. Ziegler to create Dianabol, after understanding the Soviet strongmen had to use urinary catheters, as a result of cycling testosterone in the Olympic games.
Thus, Dianabol was formulated to be less androgenic than testosterone — yet more anabolic.
Therefore, despite testosterone’s mild properties, it may not be suitable for someone with existing prostate issues or someone looking to avoid hair loss.
Testosterone Suppression
As with all anabolic steroids, testosterone will decrease endogenous testosterone levels.
Low testosterone thus can be experienced for several months after, unless a PCT (post cycle therapy) is administered to shorten this recovery period.
HCG, Clomid or/and Nolvadex can be taken post-cycle to resurrect a male’s testosterone production.
Anavar (Oxandrolone)
Anavar is an oral steroid, often used in cutting cycles to enhance fat loss and lean muscle gains.
Anavar is one of the few steroids that is adept at building muscle and burning fat simultaneously.
Muscle gains are not extreme on Anavar; however, an increase of 10-15lbs is common.
Anavar is a mild steroid, that remains FDA-approved for medicinal purposes. It is commonly prescribed to patients suffering from bone pain due to osteoporosis; and those needing to gain weight quickly (as a consequence of trauma, infection or surgery).
Interestingly, Anavar can be prescribed to women and children, without them experiencing any notable negative effects.
This demonstrates Anavar’s mild properties, with other steroids causing masculinization in women or/and being too toxic for minors.
In bodybuilding circles, Anavar is nicknamed the ‘girl steroid’, due to it being generally safe for women to take (in low to moderate doses). Many AAS in comparison will enlarge the clitoris, shrink the breasts, cause hair growth on the body; and deepen the voice.
However, many men also take Anavar, not just for bodybuilding purposes; but to dramatically increase muscular strength, power and endurance.

Legal Anavar Alternative

Anvarol is our #1 rated legal Anavar product. It replicates the fat-burning and muscle-building effects of Anavar, but without any unwanted side effects.

It is FDA-approved and can be purchased online without a prescription.

Anvarol is best suited for men or women who want to reduce their body fat percentage, whilst simultaneously increasing muscle tone and building lean muscle.

Anavar Side Effects
Liver toxicity
Oral steroids generally don’t have a positive reputation when it comes to liver health.
This is because orals are c-17 alpha alkylated, meaning they are processed by the liver before entering the bloodstream. Consequently, the organ becomes stressed with ALT and AST liver enzymes rising.
However, Anavar is one of the few exceptions to this rule, with it posing considerably less liver toxicity (compared to other orals).
It is not entirely known why this is the case; however, the kidneys playing more of a role in processing oxandrolone, compared to other compounds, may be a reasonable explanation. Thus, decreasing the liver’s workload.
Cholesterol levels
Cholesterol levels will shift in a negative way, thought to be notably less than other steroids; albeit greater than testosterone.
For an oral steroid, Anavar is certainly not the worst compound for the heart; however, its effects are notable.
Research has shown that men taking 20mg/day of Anavar for 12 weeks, experienced a 30% decrease in HDL cholesterol (8).
A 40mg/day dose of Anavar only reduced HDL levels by a further 3% (33% in total).
When taking 80mg/day the reduction was severe, dropping by 50%.
LDL levels also increased in each of the groups, at a similar rate to the drop in HDL. 
The typical bodybuilding dose for men is 20mg of Anavar per day. Also is not commonly taken for long periods of time (such as 12 weeks), but more often 6-8 weeks. Thus, a common Anavar cycle will likely yield less than a 30% decrease in HDL cholesterol; likely being closer to 20-25%.
This is not an alarming drop, however certainly something to monitor and take precautions against. Taking 4g/day of fish oil can help prevent such rises in BP, offering some level of cardiovascular protection on-cycle.
Virilization in Women
Although Anavar is viewed as a ‘female friendly’ steroid, virilization (or masculinization) can still occur in women taking high doses of it.
Doses over 10mg/day will increase the likelihood of undesirable effects, plus a cycle lasting beyond 6 weeks.
Doesn’t Aromatize
Anavar doesn’t convert to estrogen which is a positive in regards to body composition, as there will be no water retention. Consequently, this creates dry and full muscle bellies.
Also, there is no risk of gynecomastia on Anavar, due to a lack of aromatization activity.
However, low estrogen is one reason why cholesterol levels are worse on Anavar, compared to testosterone.
Testosterone Suppression
Significant decreases in natural testosterone production is a certainty when taking any steroid.
However, Anavar will not completely shut down users; but instead, cause moderate suppression.
One study reported a 45% reduction in testosterone when male subjects took 20mg and 40mg for 12 weeks (9).
This is a high dose and an excessive period of time, even by bodybuilding standards.
In comparison, a small dose of Dianabol (15mg), taken for 8 weeks can cause testosterone to drop by 69% (10).
Users can expect testosterone function to recover within several weeks post-cycle (without a PCT).
However, a PCT may be utilized to speed up this process, which also applies to female users.
Deca Durabolin
Deca Durabolin (Nandrolone) is an FDA-approved injectable steroid, used in medicine to treat anemia, osteoporosis and those suffering from various muscle-wasting diseases.
Deca Durabolin is favoured in medicine and the bodybuilding community, due to its mild nature; yet potent ability to add lean muscle and strength. It is anabolic, like testosterone, yet lacks strong estrogenic and androgenic properties.
In a trial in Sydney (Australia), 17 HIV-positive men took Deca Durabolin for 16 weeks.
They experienced ‘significant increases in weight’ (in the form of lean body mass), whilst ‘no subject experienced toxicity’ (11).
Deca Durabolin is one of the most heart-friendly anabolic steroids, with research showing it producing a subtle decrease in HDL cholesterol.
Studies administering 600mg/week of Deca for 10 weeks (9), saw a 26% reduction in HDL levels.
This effect is slightly worse than testosterone and similar to a moderate dose of Anavar.
Deca Durabolin has weak androgenic properties, thus male pattern baldness, prostate enlargement, and oily skin/acne are unlikely to trouble users.
Deca Durabolin Side Effects
Although Deca Durabolin is considered a ‘safer’ steroid in bodybuilding, it can cause some problematic side effects in other areas.
Arguably the most notorious side effect is ‘Deca dick’, which essentially is erectile dysfunction or impotence. There are two components affected, which are: inability to get an erection and reduced libido.
One reason why Deca Durabolin may have a particularly negative effect on sexual libido/performance is due to it significantly increasing prolactin levels in the bloodstream.
Prolactin inhibits the production of GnRH (gonadotropin-releasing hormone), causing less endogenous testosterone production. This naturally leads to less desire for sex.
Due to Deca Durabolin’s low androgenicity, users can experience less nitric oxide production; which is crucial for optimal blood flow. Thus, erections may become less frequent, or more difficult to attain/sustain.
This is why some bodybuilders stack androgenic compounds with Deca Durabolin, such as testosterone, helping to keep nitric oxide levels high. Also supplementing with cabergoline can keep prolactin levels stable and thus prevent ‘Deca dick’.
Estrogen
Although Deca Durabolin is not regarded as estrogenic, it converts to estrogen at 20% of testosterone.
Deca however has strong progesterone properties, which can stimulate estrogen receptors in the mammary glands; thus still posing a risk of gynecomastia.
High progesterone can also contribute to water retention, causing the typical smooth look bodybuilders possess when taking Deca in the off-season.
Testosterone suppression
A common dose of Deca is 300-400mg per week, whilst stacked with other steroids.
Research has shown 100mg of Deca per week can reduce testosterone by 57% (10).
The same trial also found 300mg per week lowered test by 70%, thus a PCT should be of high priority post-cycle.
FAQ
What is the Safest Oral Steroid?
The safest oral steroid would be oral testosterone (undecanoate). However, Anavar and Primobolan are also very mild compounds with few side effects.
The most important organs to protect during a steroid cycle are the heart and liver, and these three oral steroids are the least destructive in this regard.
For women, the safest oral is Anavar, with it arguably being the most desirable compound for preserving their femininity.
What is the Safest Steroid Cycle?
Generally, the more steroids you stack together in a cycle — the greater the side effects.
Thus, a testosterone-only cycle is believed to be the mildest protocol, hence why it’s used as the first steroid cycle among beginners. Below is a cautiously dosed testosterone cycle, suitable for novices:

The above testosterone cycle would be classed as a bulking one, with users experiencing large increases in muscular strength and hypertrophy.
An Anavar-only cycle is another popular option for users prioritizing their safety. Male bodybuilders typically take the following dosages, to keep side effects at bay:

This would be seen as a cutting cycle, taken predominantly to enhance fat burning. Anavar is also suitable for users looking to gain small to moderate amounts of muscle simultaneously.
Note: Women on Anavar should take no more than 10mg/day. Below is a typical female Anavar cycle:

Summary
Although no anabolic steroid is 100% safe, some are classed as essential medicines from leading health organizations. Several steroids are also approved by the FDA, yet remain illegal today in most countries. Steroid use only becomes legal when they are prescribed by a medical doctor for underlying health problems.
