What is clenbuterol?
In our industry, clenbuterol (better known as clen) is usually known as the “cousin” of ephedrine. That's because clen stimulates beta-2 receptors as a beta-2 agonist. Essentially, that means clenbuterol allows you to burn stored fat calories (your bodyfat) as energy before you reach other sources of fuel.

Clenbuterol is approved in certain EU countries as an asthma drug, but it's banned by the US FDA. However, it has found a home with livestock farming worldwide. It's fed to animals to increase fat free lean mass (FFL), so the animals get more muscles and less fat.

What are the benefits of clenbuterol?

Clenbuterol is mainly used as a fat-loss drug; almost exclusively in cutting cycles. Most users are amazed at the increase in lean mass after clen use. That's because studies have shown that it can increase your fat free mass and increase your basal metabolic rate (BMR), while acting as an anti-catabolic and anabolic.

Clenbuterol has amazing properties: it's a fat loss pill with the ability to aid muscle retention, decrease muscle loss and boost aerobic capacity. In simple terms, you get big and ripped!

What are the the side effects of clenbuterol?

Clen is probably one of the most controversial drugs in bodybuilding these days. Recently, if you read the message forums, people overstate the negative impact of clen all day long. Go 5 years back and clenbuterol was the savior from god for fat-loss. Well, what the heck is the truth? The truth is always somewhere in the middle.

I find that fellow bodybuilders tend to forget we are on steroid forums and in the steroid industry. We take drugs that can only be described as dangerous if you're nice, and deadly if you're in the media. Just think about it, the average UG (underground) lab produces testosterone, you inject in your body, with cooking oil, benzyl alcohol (BA) and benzyl benzoate (BB). Did you know that benzyl alcohol is used as a solvent in paint stripper, paints, inks and lacquers? Don't believe me? Read this: BA information. Now, let's move to BB. Did you know that benzyl benzoate is used as a solvent and as an ingredient in dyes? And these ingredients are just some of the poisons many of us are injecting into our bodies all the time, in some cases daily! Everything is relative, never forget that.

That being said, I don't want to detract from side effects of clenbuterol here, and, by no means, am I saying it's side effect free.


There are real sides associated with its use:

heart palpitation
abnormal sweating
blood pressure problems
heart problems

What dosages of clenbuterol can I take? How do I use it?

Clen is nothing to play with, you should always start with a low dose, around 20mcg/day and never go over 200mcg/day. In general, for men, the dose is around 60-100mcg/day. For women, 10-40mcg/day is usual.

While there are a lot of rumors on the 2 weeks on, 2 weeks off regiment with clen, they aren't based on true science. Studies have shown that fat-free mass (FFM) increased in week 6 of usage by almost 5%. (reference: J Appl Physiol (1985). 2001 Nov;91(5):2064-70.) Therefore, it's safe to assume the best results come after the first 2 weeks. The problem is there is a deregulation of the CNS (central nervous system) beta-2 receptors for most people towards the third week of use. As a result, you'll need to add anti-histamines likes Ketotifen or Benadryl to keep clen working past the first 2 weeks

With all that in mind, I find it easier to have my clients just run clenbuterol 2 weeks on, and 2 weeks off, which makes it easier all around for them.

What is the half-life of clenbuterol?

Clen half-life is around 48 hours, so after taking one dose you'll have it in your system for up to 2 days. Therefore, never high dose the first 3-4 days of your cycle. You need to get a feel for what dosage is right for you.
