It’s not an anabolic-androgenic steroid, so why is it used by bodybuilders? How does Clen work in the body to provide any benefits to a professional or amateur bodybuilder?
Clen or clenbuterol is most commonly used in post-cycle therapy/PCT or as a fat burner in a cutting stack.
Women and men both take Clenbuterol because it stimulates a faster rate of metabolism, increases energy levels and helps to suppress the appetite. Click here to visit our recommended supplier.

Clenbuterol, as a sympathomimetic amine, has an impact on the sympathetic nervous system.
Autonomic or automatic body functions are part of the sympathetic nervous system that we have no control over. Some autonomic functions of the body include:
Because it has an effect – in varying degrees – on these body functions, Clen has been taken for its:
The primary mechanism of action of Clen/clenbuterol in the body is to act as a bronchodilator. It’s often found in medications used to treat asthma, COPD, and other lung disorders.
The activity of the drug serves to dilate the smooth muscle tissues found in the bronchi inside the lungs. This allows them to relax and widen, allowing enhanced airflow.
Clenbuterol also impacts much of the same action on the smooth muscle tissues of large and small blood vessels, enhancing circulation of oxygenated blood, proteins, and other nutrients to the muscles, providing them with a greater potential to grow, differentiate, proliferate.
This mechanism of action:
While Clen doesn’t have a huge impact on muscle growth, size or strength, it can influence an environment that promotes such growth.
Clen acts as an agonist or trigger in the release of adenyl cyclase, an enzyme that is part of the process of energy production.
Adenyl cyclase plays a role in the conversion of adenosine triphosphate into adenosine monophosphate, itself a very important component of energy production and metabolism. Cyclic adenosine monophosphate (cAMP) has a thermogenic or fat-burning effects in the body.
In a roundabout way, Clen has the potential to enhance metabolism and fat-burning – though not much.
Clenbuterol is most often used in post-cycle therapy as a way to encourage weight loss. Not a lot, commonly just a few pounds.
Still, Clenbuterol can be beneficial in the final stages of body sculpting or cutting prior to a competition or an athletic event.
When looking for dosage recommendations for Clen used in a PCT cycle, a variety of dosage suggestions can be found on the Internet. These suggestions made vary in regard to:
While many bodybuilders believe that Clen can help to maintain gains in muscle mass and strength after a steroid cycle, equal numbers say that it is not effective at all.
A common dosage recommendation for use in a PCT cycle ranges:
Compare those recommendations to suggestions for medical use in the treatment of asthma, where the average is 20 mcg a day.
The higher the dosage, the higher the risk for side effects.
A two-day on, two-day off cycle is common, although that can extend in terms of length to two to three weeks on and two to three weeks off. It all depends on personal preferences, expectations and results.
Because clenbuterol is not an anabolic androgenic steroid, beginning bodybuilders may feel there’s nothing to worry about when it comes to use of Clen at the end of a cycle.
However, any drug that has an impact on hormone levels, metabolism, and even the sympathetic nervous system should be used with caution.
Some of the more serious side effects associated with Clen involve the functions of the sympathetic nervous system and can contribute to:
Potential users of clenbuterol with or without other drugs should be aware that it can have an influence over blood sugar (glucose) levels in the body.
It has been recently reported that clenbuterol can have a negative impact on the heart muscle.
Use Clen cautiously. It can and does cause side effects.
