[FONT=&quot]Synovex is a blended-ingredient steroid implant preparation,[/FONT]
[FONT=&quot]which is available only as a veterinary item for use in[/FONT]
[FONT=&quot]cattle.The implant comes in the form of small pellets, which[/FONT]
[FONT=&quot]are pushed into the ear of an animal with a very large implant[/FONT]
[FONT=&quot]gun. Once implanted, the pellets slowly dissolve, providing[/FONT]
[FONT=&quot]an extended release of steroids for many weeks. The[/FONT]
[FONT=&quot]hormone content of Synovex is mixed, with each pellet[/FONT]
[FONT=&quot]containing 25 mg testosterone propionate and 2.5 mg[/FONT]
[FONT=&quot]estradiol benzoate. This 10:1 ratio has been demonstrated to[/FONT]
[FONT=&quot]provide an added anabolic/weight gaining effect in feed[/FONT]
[FONT=&quot]animals, improving the value of the livestock. Given its[/FONT]
[FONT=&quot]estrogen content, Synovex is clearly not an ideal steroid for[/FONT]
[FONT=&quot]humans. Most athletes have only become attracted to this[/FONT]
[FONT=&quot]product out of sheer desperation for legitimate anabolics, as[/FONT]
[FONT=&quot]cattle implants like this are not regulated as controlled[/FONT]
[FONT=&quot]substances in the U.S. to spite their steroid content.[/FONT]
[FONT=&quot]Otherwise, a pure testosterone propionate product would be[/FONT]
[FONT=&quot]much more appropriate.[/FONT]
[FONT=&quot]History:[/FONT]
[FONT=&quot]Testosterone propionate plus estrogen implant pellets were[/FONT]
[FONT=&quot]first approved by the U.S. Food and Drug administration for[/FONT]
[FONT=&quot]use in heifers in 1958.591 Diethylstilbestrol, a potent estrogen[/FONT]
[FONT=&quot]often used to increase animal carcass weight, had been[/FONT]
[FONT=&quot]approved four years earlier for use in cattle, however, and[/FONT]
[FONT=&quot]would remain the leading product for many years. Syntex[/FONT]
[FONT=&quot]introduced their version of testosterone/estrogen pellets[/FONT]
[FONT=&quot](Synovex) during the early 1970’s, as part of the company’s[/FONT]
[FONT=&quot]new Animal Health division. This was during a time a time[/FONT]
[FONT=&quot]when diethylstilbestrol was getting a great deal of negative[/FONT]
[FONT=&quot]publicity. Synovex became a huge seller when the FDA[/FONT]
[FONT=&quot]banned the use of diethylstilbestrol in 1973, the product[/FONT]
[FONT=&quot]quickly capturing more than 50% of the market for growthpromoting[/FONT]
[FONT=&quot]implants. The popularity of Synovex soon caught[/FONT]
[FONT=&quot]the attention of other companies, a number of which soon[/FONT]
[FONT=&quot]started making their own blended testosterone/estrogen[/FONT]
[FONT=&quot]implants. Popular brand names in the U.S. have included FTO[/FONT]
[FONT=&quot](Upjohn), Heifer-oid (Boehringer), and Implus (Upjohn).[/FONT]
[FONT=&quot]Synovex and other testosterone/estrogen pellets remain[/FONT]
[FONT=&quot]widely available in the U.S. and abroad today, although are[/FONT]
[FONT=&quot]not highly popular with athletes given their estrogen content.[/FONT]
[FONT=&quot]How Supplied:[/FONT]
[FONT=&quot]Synovex contains 25 mg of testosterone propionate and 2.5[/FONT]
[FONT=&quot]mg of estradiol benzoate in a small sterile implantation[/FONT]
[FONT=&quot]pellet. The number of pellets in each cartridge dose will vary[/FONT]
[FONT=&quot]depending on the intended target animal. Implants denoted[/FONT]
[FONT=&quot]“H” for heifer will carry the most; in the case of U.S.[/FONT]
[FONT=&quot]Synovex-H it is 80 pellets (10 doses consisting each of 8[/FONT]
[FONT=&quot]pellets). We will see a slightly lower pellet count in the “S”[/FONT]
[FONT=&quot]implants (steer) and “C” (calf ) cartridges.[/FONT]
[FONT=&quot]Structural Characteristics:[/FONT]
[FONT=&quot]Testosterone propionate is a modified form of testosterone,[/FONT]
[FONT=&quot]where a carboxylic acid ester (propionic acid) has been[/FONT]
[FONT=&quot]attached to the 17-beta hydroxyl group to slow the release of[/FONT]
[FONT=&quot]testosterone from the area of implantation. This preparation[/FONT]
[FONT=&quot]also contains an ester (benzoic acid) of estradiol.[/FONT]
[FONT=&quot]Side Effects (Estrogenic):[/FONT]
[FONT=&quot]Testosterone is readily aromatized in the body to estradiol[/FONT]
[FONT=&quot](estrogen). Additionally, this preparation contains an active[/FONT]
[FONT=&quot]estrogen. Elevated estrogen levels can cause side effects[/FONT]
[FONT=&quot]such as increased water retention, body fat gain, and[/FONT]
[FONT=&quot]gynecomastia. This steroid preparation is considered to be[/FONT]
[FONT=&quot]highly estrogenic. An anti-estrogen such as clomiphene[/FONT]
[FONT=&quot]citrate or tamoxifen citrate may be necessary to prevent[/FONT]
[FONT=&quot]estrogenic side effects. One may alternately use an aromatase[/FONT]
[FONT=&quot]inhibitor like Arimidex® (anastrozole), although it will not[/FONT]
[FONT=&quot]have an affect on the additional estrogen present in the[/FONT]
[FONT=&quot]preparation. Since water retention and loss of muscle[/FONT]
[FONT=&quot]definition are common with highly estrogenic steroid[/FONT]
[FONT=&quot]products, this drug is usually considered a poor choice for[/FONT]
[FONT=&quot]dieting or cutting phases of training. It would only be[/FONT]
[FONT=&quot]appropriate during bulking phases, where the added water[/FONT]
[FONT=&quot]retention will support raw strength and muscle size, and help[/FONT]
[FONT=&quot]foster a stronger anabolic environment.[/FONT]
[FONT=&quot]Side Effects (Androgenic):[/FONT]
[FONT=&quot]Testosterone is the primary male androgen, responsible for[/FONT]
[FONT=&quot]maintaining secondary male sexual characteristics. Elevated[/FONT]
[FONT=&quot]levels of testosterone are likely to produce androgenic side[/FONT]
[FONT=&quot]effects including oily skin, acne, and body/facial hair growth.[/FONT]
[FONT=&quot]Men with a genetic predisposition for hair loss (androgenetic[/FONT]
[FONT=&quot]alopecia) may notice accelerated male pattern balding.[/FONT]
[FONT=&quot]Those concerned about hair loss may find a more[/FONT]
[FONT=&quot]comfortable option in nandrolone decanoate, which is a[/FONT]
[FONT=&quot]comparably less androgenic steroid. Women are warned of[/FONT]
[FONT=&quot]the potential virilizing effects of anabolic/androgenic[/FONT]
[FONT=&quot]steroids, especially with a strong androgen such as[/FONT]
[FONT=&quot]testosterone. These may include deepening of the voice,[/FONT]
[FONT=&quot]menstrual irregularities, changes in skin texture, facial hair[/FONT]
[FONT=&quot]growth, and clitoral enlargement.[/FONT]
[FONT=&quot]Side Effects (Hepatotoxicity):[/FONT]
[FONT=&quot]Testosterone and estrogen do not have hepatotoxic effects;[/FONT]
[FONT=&quot]liver toxicity is unlikely.[/FONT]
[FONT=&quot]Side Effects (Cardiovascular):[/FONT]
[FONT=&quot]Anabolic/androgenic steroids can have deleterious effects on[/FONT]
[FONT=&quot]serum cholesterol. This includes a tendency to reduce HDL[/FONT]
[FONT=&quot](good) cholesterol values and increase LDL (bad)[/FONT]
[FONT=&quot]cholesterol values, which may shift the HDL to LDL balance[/FONT]
[FONT=&quot]in a direction that favors greater risk of arteriosclerosis. The[/FONT]
[FONT=&quot]relative impact of an anabolic/androgenic steroid on serum[/FONT]
[FONT=&quot]lipids is dependant on the dose, route of administration (oral[/FONT]
[FONT=&quot]vs. injectable), type of steroid (aromatizable or nonaromatizable),[/FONT]
[FONT=&quot]and level of resistance to hepatic metabolism.[/FONT]
[FONT=&quot]Testosterone tends to have a much less dramatic impact on[/FONT]
[FONT=&quot]cardiovascular risk factors than synthetic steroids. This is[/FONT]
[FONT=&quot]due in part to its openness to metabolism by the liver, which[/FONT]
[FONT=&quot]allows it to have less effect on the hepatic management of[/FONT]
[FONT=&quot]cholesterol. The aromatization of testosterone to estradiol[/FONT]
[FONT=&quot]also helps to mitigate the negative effects of androgens on[/FONT]
[FONT=&quot]serum lipids. The added estrogen in this product may further[/FONT]
[FONT=&quot]help to offset some of the androgenic effect on lipid values,[/FONT]
[FONT=&quot]and the preparation may, therefore, have a weaker impact on[/FONT]
[FONT=&quot]cholesterol than a comparably dosed straight testosterone[/FONT]
[FONT=&quot]product. Anabolic/androgenic steroids may also adversely[/FONT]
[FONT=&quot]affect blood pressure and triglycerides, reduce endothelial[/FONT]
[FONT=&quot]relaxation, and support left ventricular hypertrophy, all[/FONT]
[FONT=&quot]potentially increasing the risk of cardiovascular disease and[/FONT]
[FONT=&quot]myocardial infarction.[/FONT]
[FONT=&quot]Side Effects (Testosterone Suppression):[/FONT]
[FONT=&quot]All anabolic/androgenic steroids when taken in doses[/FONT]
[FONT=&quot]sufficient to promote muscle gain are expected to suppress[/FONT]
[FONT=&quot]endogenous testosterone production. Testosterone is the[/FONT]
[FONT=&quot]primary male androgen, and offers strong negative feedback[/FONT]
[FONT=&quot]on endogenous testosterone production. The added estrogen[/FONT]
[FONT=&quot]will also provide negative-feedback suppression. This[/FONT]
[FONT=&quot]preparation should have a strong effect on the hypothalamic[/FONT]
[FONT=&quot]regulation of natural steroid hormones. Without the[/FONT]
[FONT=&quot]intervention of testosterone stimulating substances,[/FONT]
[FONT=&quot]testosterone levels should return to normal within 1-4 months[/FONT]
[FONT=&quot]of drug secession. Note that prolonged hypogonadotrophic[/FONT]
[FONT=&quot]hypogonadism can develop secondary to steroid abuse,[/FONT]
[FONT=&quot]necessitating medical intervention.[/FONT]
[FONT=&quot]To help reduce cardiovascular strain it is advised to[/FONT]
[FONT=&quot]maintain an active cardiovascular exercise program and[/FONT]
[FONT=&quot]minimize the intake of saturated fats, cholesterol, and simple[/FONT]
[FONT=&quot]carbohydrates at all times during active AAS administration.[/FONT]
[FONT=&quot]Supplementing with fish oils (4 grams per day) and a natural[/FONT]
[FONT=&quot]cholesterol/antioxidant formula such as Lipid Stabil or a[/FONT]
[FONT=&quot]product with comparable ingredients is also recommended.[/FONT]
[FONT=&quot]Administration (General):[/FONT]
[FONT=&quot]Synovex implant pellets were not designed for human[/FONT]
[FONT=&quot]consumption. To make use of these pellets, they must be[/FONT]
[FONT=&quot]converted into another (more suitable) delivery form. To do[/FONT]
[FONT=&quot]this, an athlete will typically grind them up and rub them on[/FONT]
[FONT=&quot]the skin in a 50/50 mixture of DMSO and water to facilitate[/FONT]
[FONT=&quot]transdermal delivery. Alternately, one may mix up a[/FONT]
[FONT=&quot]homebrew injection with the pellets. This is done by grinding[/FONT]
[FONT=&quot]them into a fine powder and introducing the powder into[/FONT]
[FONT=&quot]filtered oil or an oil-based steroid. One should remember[/FONT]
[FONT=&quot]that the practice of preparing Synovex for injection is not[/FONT]
[FONT=&quot]going to be sterile, and as such could be potentially[/FONT]
[FONT=&quot]dangerous. Note that some methods have additionally been[/FONT]
[FONT=&quot]published for removing the estrogen from the pellets, to make[/FONT]
[FONT=&quot]the drug more comfortable to use. They generally involve the[/FONT]
[FONT=&quot]use of highly flammable materials, take a number of different[/FONT]
[FONT=&quot]steps to complete, and leave some estrogen when the process[/FONT]
[FONT=&quot]is over, however, usually making the process more trouble[/FONT]
[FONT=&quot]than it is worth.[/FONT]
[FONT=&quot]Administration (Men):[/FONT]
[FONT=&quot]Synovex is not approved for use in humans. Prescribing[/FONT]
[FONT=&quot]guidelines are unavailable. When used for physique- or[/FONT]
[FONT=&quot]performance-enhancing purposes (very rarely), the dose is[/FONT]
[FONT=&quot]calculated based on the route of administration. When given[/FONT]
[FONT=&quot]by transdermal delivery, a bioavailability rate of no more[/FONT]
[FONT=&quot]than 10% is assumed. A daily dosage of 4 pellets (100 mg)[/FONT]
[FONT=&quot]would, therefore, provide the equivalent of 70 mg per week[/FONT]
[FONT=&quot]of testosterone propionate (as given by injection). When[/FONT]
[FONT=&quot]given by injection a dose of 100 mg every second or third[/FONT]
[FONT=&quot]day is most common. The drug is generally taken for no more[/FONT]
[FONT=&quot]than 8 weeks, and is used almost exclusively during bulking[/FONT]
[FONT=&quot]phases of training. Those who have experimented with this[/FONT]
[FONT=&quot]product have been generally disappointed with the results, as[/FONT]
[FONT=&quot]the added estrogen has often resulted in rapid gynecomastia,[/FONT]
[FONT=&quot]noticeable body fat accumulation, and severe water retention.[/FONT]
[FONT=&quot]In many cases the water retained has caused an unsightly[/FONT]
[FONT=&quot]bloated look (extreme loss of definition).[/FONT]
[FONT=&quot]Administration (Women):[/FONT]
[FONT=&quot]Synovex is not approved for use in humans. Prescribing[/FONT]
[FONT=&quot]guidelines are unavailable. Synovex is not recommended for[/FONT]
[FONT=&quot]women for physique- or performance-enhancing purposes[/FONT]
[FONT=&quot]due to its strong androgenic nature and tendency to produce[/FONT]
[FONT=&quot]virilizing side effects.[/FONT]
[FONT=&quot]Availability:[/FONT]
[FONT=&quot]Synovex is rarely found on the black market, given that the[/FONT]
[FONT=&quot]product is in poor demand and generally can be obtained[/FONT]
[FONT=&quot]through legitimate Agricultural or Veterinary supply stores.[/FONT]
[FONT=&quot]No counterfeits have ever been known to exist.[/FONT]
