Clenbuterol FAQ: Everything you need to know about Clen I wrote this because of all the confusion that surrounds this drug. Enjoy.
What is Clenbuterol? Clenbuterol is a beta-2 agonist and is used in many countries as a broncodilator for the treatment of asthma. Because of itís long half life, Clenbuterol is not FDA approved for medical use. It is a central nervous system stimulant and acts like adrenaline. It shares many of the same side effects as other CNS stimulants like ephedrine. Contrary to popular belief, Clenbuterol has a half life of 35 hours and not 48 hours.
Dosing and Cycling Clenbuterol comes in 20mcg tablets, although it is also available in syrup, pump and injectable form. Doses are very dependent on how well the user responds to the side effects, but somewhere in the range of 5-8 tablets per day for men and 1-4 tablets a day for women is most common. Clenbuterol loses its thermogenic effects after 6-8 weeks when body temperature drops back to normal. Itís anabolic/anti-catabolic properties fade away at around the 18 day mark. Taking the long half life into consideration, the most effective way of cycling Clen is 2 weeks on/ 2 weeks off for no more than 12 weeks. Ephedrine can be used in the off weeks. Clenbuterol vs Ephedrine vs DNP
Ephedrine will raise metabolic levels by about 2-3 percent and 200mg of DNP raises metabolic levels by about 30 percent. Clenbuterol raises metabolic levels about 10 percent and it can raise body temperature several degrees.
DNP is by far the most effective fat burner but many people will never use it because of the risks associated with it. It also offers no anti-catabolic benefit. Although it does have anti-catabolic effect, ephedrine short half life prevents it from being all that effective.
As far as side effects, Clenbuterolís are certainly milder than DNPís, and some would even say milder than an ECA stack. There is no ECA-style crash on Clenbuterol and many users find it easier on the prostate and sex drive. This may in part be due to the fact that Clen is generally used for only 2 weeks at a time.
INCREASED BLOOD PRESSURE
The most significant side effects are muscle cramps, nervousness, headaches, and increased blood pressure.
Muscle cramps can be avoided by drinking 1.5-2 gallons of water and consuming bananas and oranges or supplementing with GNC potassium tablets at 200-400mg a day taken before bed on an empty stomach.
Headaches can easily be avoided with Tylenol Extra Strength taken at the first signs of a headache. You may need to take double the recommended dose.
Post-Cycle Therapy: Clen is used post cycle to aid in recovery. It allows the user to continue eating large amounts of food, without worrying about adding body fat. It also helps the user maintain more of his strength as well as his intensity in the gym. Diet: Roughly the same as on cycle.
Fat loss: The most popular use for Clen, it also increases muscle hardness, vascularity, strength and size on a caloric deficit. For the most significant fat loss, Clen can be stacked with t3. Diet: A high protein(1.5g per lb of bodyweight), moderate carb(0.5g to 1g per lb of bodyweight), low fat diet(0.25g per lb of bodyweight) seems to work best with Clen.
Alternative to Steroids: Clenbuterol has mild steroid-like properties and can be used by non AS using bodybuilder to increase LBM as well as strength and muscle hardness. Diet: A moderate carb, high protein, moderate fat diet work well.
Stimulant/Performance Enhancement: It can be used as a stimulant, but an ECA stack may be a better choice because of itís much shorter half-life. Diet: To take full advantage of the stimulatory effects of Clen, Carbs must be included in the diet. Keto diet do not work well in this case.
Precautions: Is Clen for you?
The same precautions that apply to Ephedrine must be applied to Clen, although some people find ECA stacks harsher than Clen. It should not be stacked with other CNS stimulants such as Ephedrine and Yohimbine. These combinations are unnecessary and potentially dangerous. Caffeine can be used in moderation before a workout for an extra kick, although its diuretic effects may shift electrolyte balance. Drink more water if you use Caffeine.
What else do I need to know?
Most users that report bad side effects and discontinue use are those who use high doses right at the start of the cycle. The worst side effects occur within the first 3-4 days of use.
A first time user should not exceed 40mcg the first day.
Example of a first cycle:
Day5: 80mcg(Note: Increase the dose only when the side effects are tolerable)
Day13: 80mcg (Tapering is not necessary, but it helps some users get back to normal gradually)
Day 17: ECA/ NYC stack
Example of a second cycle:
Day 17: ECA/ NYC stack
Do not take Clen Past 4pm and drink plenty of water: 1.5-2 gallons a day.
All brands are not equal when it comes to Clen, different brands will yield different results.
That about covers everything.
Presser, thanks for the article I found it very useful. I'm about to start a cycle for the first time next week.
One question in terms of your dosage suggestion. Do you take tablets through out the day I.e. On 60mcg day one in the morning, one mid morning and then one early afternoon, or do you ou just take them all in one go, say, in the morning?

Lend me your eyes I can change what you see, but your soul you must keep totally free!! INFJ .03%
I am in the Army.. Do you know if this shows up on a drug test as anything? Thanks!!
I dropped weight quick on that stack (clen and T3). As soon as I was off it all came back with more

I just got off cycle and this article makes me want to run a clen cycle. hmmm. why not! Sounds like a good idea to help with my priming for next cycle to lose some bf.
All bullshit aside. I read this article an within an hour made a clen purchase. haha. I am way too easily excited. :-p
I may need something like this. I thought giving up beer and eating right would do it but i haven't lost a pound in 6 weeks... I need one of those pinchers to measure progress.... i actually gained weight but I know it can't be fat.
Well it was nice to get a two week break to feel normal. Counting down the days to take it and today is the day. Within thirty mins back to shaking like a leaf. haha. here we go again.
What is Clenbuterol and what does it do?
Clenbuterol (often referred to simply as 'Clen') is not a steroid, but a Beta 2 Sympathomitetic and central nervous system (CNS) stimulant. It is a specific agonist, stimulating the adrenergic beta 2 receptors. It is used in certain countries in a medical sense as a bronchodilator in the treatment of asthma, though not in the UK and USA, mainly due to its long half life.
Athletes and bodybuilders use the drug due to its thermogenic and anti-catabolic effects. This is down to its ability to slightly increase the body's core temperature, thereby raising calorie (energy) expenditure. It is thought that a 1įF increase yields around a 5% increase in maintenance calories burned. Studies on livestock suggest that clenbuterol also has anabolic properties. However, this seems not to be the case in humans, thought to be due to the fact that humans lack the abundance of beta 3 receptors which increase insulin production and sensitivity.
Clenbuterol is dosed in micrograms (mcg/Ķg), most commonly in tablet form, though there are other forms of administration such as liquids, nasal sprays and injectables. Note: Although dosages are in microgram amounts, many manufacturers will list the active ingredient as milligrams (mg), so a tablet of 20mcg will be labelled as 0.02mg.
Clenbuterol side effects/possible implications?
Side effects are dose dependant, though most users will find that most tend to subside with persistent use. Caution is advised when employing the use of Clenbuterol in conjunction with other adrenoceptor agonists as side effects are likely to be cumulative. It is for this reason that it is generally not recommended to use ephedrine/ephedra (or ma huang) or the ECA stack (ephedrine-caffeine-aspirin) whilst using clen.
Common side effects of clenbuterol include:
Muscular tremors (especially hand shakes)
Hypertension (high blood pressure)
Possible cardiac hypertrophy as clen also targets cardiac and smooth muscle fibres
Heart muscle necrosis has been demonstrated in animal studies
In view of the above side effects, it is obvious to assume that anyone with cardiac issues and/or hypertension should not use a stimulant such as Clenbuterol and caution must be observed by those already using similar compounds in the treatment of existing medical conditions. In addition, there is very little conclusive knowledge of the cardiac effects of supra-physiological dosages in humans.
Commonly used doses
It is well known that Clenbuterol use results in rapid down-regulation of beta 2 receptors. This is due to the powerful stimulatory effect of the drug. It is therefore pointless to use clen for long periods without a break. Some believe that a two day on, two day off dosing schedule will allow adequate potential for receptor up-regulation. However, I doubt this to be the case due to the relatively long half life of clen, resulting in continued stimulation even throughout the 'off' days. A much better regime would be a two week on, two week off cycle. Maximum plasma levels are reached around 2-3 hours after oral administration, and terminal half life at 34 hours (Zimmer, 1976).
A tapering up of dosages is recommended in an attempt to limit harsh side effects. Most commonly, a user will start by taking one 20mcg tablet on day 1, followed by an increase of one tablet on subsequent days. Subject to personal tolerance levels, a dosage of 140mcg (seven tabs) will be used by day 7, and this level should be maintained for the entire second week. It would be fruitless to exceed seven or eight tablets daily due to receptor over-saturation. There is no requirement to taper down.
For the next 'cycle' of clen (i.e. weeks 5 & 6), there is no requirement to taper up from one tablet as your tolerance level should now be known. As an example, if the user finished the first cycle of clen on 7 tabs, they could recommence at a slightly lower dose of 4 or 5, and taper up again from this level. Again though, the user should again limit their intake to 7 or 8 tabs daily.
During the two 'off' weeks, an ECA stack can be used as required. ECA will not cause such a pronounced down regulation and desensitization of the receptors, certainly not to the extent of clen. Ephedrine has a short half life in contrast to clen which results in times throughout the day where the betas will partially recover from stimulation by adrenaline and nor-adrenaline. Potency is also much weaker that that of clen, as it is not a specific agonist. Ephedrine is also thought to increase the conversion of endogenous/exogenous T4 to T3 through the activation of deiodinase enzymes responsible for this process. This is important as clen is known to slow the rate of T4 to T3 conversion. As a side note, some bodybuilders will use T3 concurrently with the Clenbuterol/ECA cutting cycle (together with certain anabolic/androgenic steroids no doubt!) in an attempt to at least maintain plasma T3 levels.
Cycles of Clen/ECA are normally limited to 12 weeks in total, though are often shorter.
Female dosages tend to be slightly lower than those of male users, with an upper limit of 80-120mcg (4-6 tabs).
Aside from its fat burning properties, Clen is often used as an anti-catabolic to maintain muscular gains following a steroid cycle. A dosage of 40mcg daily would be suited to this situation.
There is no particular requirement to split the dosage throughout the day due to the long half life. Most will take the full daily dose in the morning, though some prefer to take their dose just before bed in an attempt to avoid most of the side effects as they sleep.
Some user accounts suggest that splitting the dose may lessen side effects slightly. It is a trial and error process in essence, to ascertain which method suits you personally.
Cramping whilst using Clenbuterol is a fairly common side effect. This is most probably due to depletion of the amino acid taurine in the liver together with deficits in the electrolytes sodium and potassium, as well as inadequate hydration. Taurine helps stabilize cell membranes and prevent nerves from becoming over-excited. Some studies show that giving taurine supplements relieves painful muscle cramps. Japanese researchers found that the longer rats exercised, the more taurine they lost from their muscles (Matsuzaki et al, 2002).
Symptoms of cramping may be alleviated by:
Eating fruit particularly bananas
Ensuring adequate hydration
Taurine supplementation - 3-5g daily
Potassium supplementation - 200-400mg daily taken before bed on an empty stomach
Ketotifen is an anti-histamine used medically to treat bronchial asthma and allergies. It has a sedative and depressant effect on the brain. It acts by decreasing the release of histamine which is a chemical released when an allergic reaction occurs. Ketotifen blocks the action of histamine on special histamine receptors and reduces the nerve response when an allergic reaction occurs.
Histamine is the chemical in the body that causes the symptoms of an allergic (hypersensitivity) reaction. These can include inflammation of the skin, airways or tissues, rashes, itching and of the skin, eyes or nose, nasal congestion and narrowing of the airways. By blocking the actions of histamine, ketotifen may prevent and relieve the narrowing of the airways that occurs in asthma due to allergies.
However, bodybuilders are interested in the drug as it has been shown to inhibit the down regulation of the beta receptors, including the beta 2s that clen stimulates. As long as you are taking ketotifen, it will continue to clean these receptors, never allowing them to downregulate, even while on a heavy clen cycle. That means you can continue to take clen indefinitely without having to cycle off to regenerate the receptors. A dose of 2-3mg daily can upregulate even severely shut down receptors within a week.
It also means that you don't need as much clen to get the same benefits. It seems you can take about 30-40% less clen and it be equally effective.
No studies have been done to find the most effective dose though most users should find 3-4mg daily ideal, which can be split or taken in one sitting. Higher doses are likely to cause (sometimes severe) drowsiness and increase appetite.

What's up fellas! Noob to the site and likin it. Just ordered the aqua burn & cyto burn combo for the wife and I. Couldn't really find a good clen stack to go with, but after doin much research on this site we thought the aqua and cyto seemed pretty good. For those out the who have used it, what can be expected comparing this to clen and t3? And also dealing with cyber suppz? They seem pretty legit but just wanting to seeing what every one else thinks. My stats by the way are 5'7" 226# around 16-18% bf.
- - - Updated - - -
And bump for an awesome post concerning clen. Great info.
The comparison is remarkable bro ! Be careful with it! SERIOUSLY !!
Cool! Thanks fellas! I'm actually pretty pumped about trying this out. Thanks for a the precautions and I'll be sure to follow them no doubt. Anyone have a wag for dosing? I can probably figure out mine but any further info is awesome, but as for the wife, that is a different story. She's 5'4" about 120-125% ish. Maybe in the 10-15% bf range.
just remember the aqua-burn is 200mcg per 1ml, and 1ml is one filled dropper, you DO NOT wanna take one filled dropper, you want to start with 1/10th of that which would be 20mcgs,
Why are keto diets ineffective with clen? What will prevent clen from burning fat on keto? I tried google but couldn't find anything.
welcome to MC nubly. try starting a new thread to get more responses
Hi Mr. Presser. I want to ask a question. I did some googling and could not find an answer. I was about to start taking Clen till I realized something.
I have Glucose-6-phosphate dehydrogenase (G-6-PD) deficiency. Can I still take Clen (only clen, not stacking with anything else) ? I'm worried i'd die on the 1st day of clen.
P/S: thank you for such informative thread on clen.
im a a first time user of clean ...female 38 yo. As I gradually increase the dosage, do you take the full dosage in the morning or throughout the day. For ex, on the 80mg day, take all at once in the morning or in 2, 4 different times during the day?
This is the number one thread at MC with almost 80,000 views. 79,285 to be exact. Lots of people trying to cut. Maybe Lindsay, or Brittany looked it up here before they took a cycle. Allegedly
Thank u for another great thread
ONE MORE REP YEAH BUDDY
Thanks guys!!! I appreciate the help. Here's to day 1
Hey all. Newbie here. Started a clen cycle for the first time today. 20mcg to start. I'll be taking progress pictures, if it works out I'll post them haha.

Newbie here. Great info here as well. Just started my 1st clen cycle 4 days ago. Today is my 1st day @ 120 mcg/day and have experienced no shakes thus far. Are shakes a sure sign? I have experienced a slight headache. I dont take them all at once, i split them into 2 dosings a day. So are shakes a sure thing?
When I started using clen I could do 200 MCG dose daily but after stoping and starting again on my each clen cycle my tolerance level has gone down now even 20 mcg give me nightmares and trouble sleeping , increased bp 200/90 , could feel my heart trying to pump out of my Chest lol , even had to use xanax to calm down lol
Ahh good ole clen I tried it back in the day. Snagged from Mexico and it made me jittery as all get out but I could put in a 3 hour workout and feel like I hadn't even lifted. Well maybe that was the anadrol.
Thanks I am using clen for the first time I have 100 x 40mcg tabs my partner is allowing me to half a tab for first couple of days then increase, I only want to lose weight and tone up have you any suggestions of work outs that are not bodybuilding workouts lol
- - - Updated - - -
I am using for first time purely for weigh loss any advice? xo
how long you've been lifting
My height is 5ft 8'8inch I have a medium body build I weigh 12st 7lb I am doing 30 mins exercise a day mostly cardio like zumba and then some toning excercises, I haven't been lifting my goal is to drop weight not wanting to make huge muscles although I know I can lift without this happening don't know how though and my goal is to drop 2 stone obviously not on first cycle?? I don't know honestly thanks for your reply look forward to hearing from you xo
At your current weight I honestly don't think you would notice a huge difference in adding this to your routine, although you could see some. I think clen is best used to get rid of the last few lbs the diet and exercise just can't seem to rid you of.
Is your diet clean? and are you currently dropping weight with what you are currently doing at the moment? Low carb it, high protein, etc look into your macro's make sure it's all where they should be. Once you hit a wall and stop seeing results THEN add clen or ECA stack (ephedrine/caffeine/aspirin)
As far as building muscle goes. Women do not have the hormonal capacity to natural get bulky ESPECIALLY while dieting and STRONGLY recommend throwing more of the weight around in your routine. You will see your body tighten up and get more toned because of it (more muscle used also means more cals burned).
Resistance weight training has been shown to burn more calories through out the day than a session of cardio. Also the more muscle your body puts on the more energy (macros) it will need to maintain itself. That means your body will burn more fat.
Cardio work your cardiovascular system (heart lungs) It does help with weight loss, yes, but it is most beneficial when combined with proper diet and exercise routine. Once and if your at this point, then add clen. You will then really see it shine in your use of it.
Friend told me to do not do cardio while on clen cycle. Good or bad advice?
Don't drink alcohol. I've heard that one. Never heard the cardio one. I don't think your friend gave you good advice honestly. What are you just supposed to take clen and do what...just lift weights? What if your heart rate gets elevated lifting weights? Are you going to have a heart attack? Don't drink alcohol and stay hydrated and watch your bp. I would limit the caffeine intake maybe. Stay more hydrated if you drink caffeine on clen and also do a session of cardio. Maybe take it easy till you know how you react you know. Don't go start clen and run a fuckin marathon.

You can cardio just watch BP. Guy doesn't know what he is talking about it sounds like
Dim ME tha BOLD (Gimme the BOLD!!)
Ive been using clen for a couple of weeks doing the 2 days on 2 days off type of cycle as this fits my lifestyle better than the 2 weeks on 2 weeks off...
Well on tuesday i was prescribed some antibiotics for a problem with my balls lol. I have to take these twice a day for 10 days and i was just wondering if it was safe to continue to take my clen whilst on the antibiotics? I really dont want to have to stop my cycle so soon
The antibiotics are called 'Ciprofloxacin'.
Any help would be greatly appreciated, cheers in advance!
Ill only be doing 80mcg while on them. I should be taking 80 today and 80 tomorrow (both after morning training), then wednesday and thursday ill be off for two days and so on. My course of antibiotics will finish on tuesday next week. But I dont want to come off clen and have to start again
Just an update for everybody. I stopped the Clen I was using from LaPharma. Not sure if it was just underdosed or counterfeit. The hologram matched their website's version but Im sure counterfeiters could replicate anything.
Anyhow, I had been doing the 2 week on 2 week off cycle, but quit at the end of the 2nd week. I hade made my way up to 200 mcg/day while feeling absolutely no side effects. I have high tolerance for stims but from all that Ive talked to and read, I shouldve felt something. So for precautionary sake, I tossed the "Clen" in the trash. I dont know what I was taking and I wasnt gonna continue to put myself at a potential risk with mystery pills.
Not bashing LaPharma, but find a supplier you know and trust. Ive got about 7% BF to lose to get to my goal of 5%. And so far hitting the cardio a little harder and lifting with less rest between sets is working. Diet is and always has been clean since i started as well.
Props to this thread and website for a lot of helpful info.
Before anybody starts assuming my work ethic is shit and Im trying to take a shortcut, I was 275 lbs with 33% bodyfat a year ago. Im now 215 lbs 12% and Ive put on about 12 lbs of muscle. So ive been working hard. Im at a plateau right now, and the clen was my hopeful means to break it.
i was recommended Lapharma by a buddy who had gotten his in the past from there.
Who knows what happened, something obiously. Glad its working for you.
I started keto 2 weeks ago and am torching away the fat again. So i just lost a few bucks and learned a lesson out of it. Good luck reaching your goals everyone.
Ok no abuse please guys im just trying to get as much info on clenbuterol dosages.
So im female, 27yrs, 5ft & 9st 6lbs, I excersise twice a day (light weights in the morning & cardio in the late afternoon/eve) I eat clean so no carbs and I still cant bloody shift the weight so im contemplating using clenbuterol.
Im fully aware of the side effects but im wary to what dosage and times to take it and days off etc along with having to take additional supplements.
Please note im in the UK if things are named diff here.
Thanks in advance guys x
great advice, though you might wanna start at 20mcgs being a female, but 40mcgs shouldn't kill ya if you go that route, just my opinion hun
Also If you start a new thread, you will get many more replies and much more help, rather then posting in this thread pages and pages back, it kind of gets lost when asking questions this deep into a thread,
anyhow, welcome to MC and if you have any questions feel free to start a new thread
Ok thank you, do I need to take anything with the clenbuterol? also what do I do when I hit the max dosage on say for eg the 9th day? do I continue on the max until the end of the 2 weeks and then start again at 40 after my 2 week rest? Please bare in mind ive never taken this type of stuff before and im not schwarzeneggers like you lot x
- - - Updated - - -
ok just got your message presser, I shall write a new thread x
ok well I think ive posted a thread correctly, thanks for the help! x
GO BEAST MODE!!!
Awesome thanks, do I continue to take potas and tau while on the 2 week break? x
ok thanks xx
Just a thought......can I do ECA while on clen along with potassium & taurine or will I end up killing myself?!?! x
Ok so....clen potass & tau for 2 weeks then 2 week break having eca then clen potass & tau and so on...
Awesome thank you guys!! xxx
Hey guys just a quick one...I started the clen with potassium and taurine today, can I also add t3's to the mixture? also where do you recommend getting the eca stack from and should I take the t3s with the eca stack also?
So many of my questions have been answered in this thread except for a few. If I'm going to be doing 2 weeks on and 2 weeks off of Clen with ECA during my 2 weeks off, should I take ketotifen at all? Next question, the example at the top of the page has two days off of everything after the 14 days on Clen. Should I wait 2 days after I finish Clen before starting ECA for two weeks or can I go right into the ECA? Thanks!
