Clenbuterol 50 tab. (40 μg/1 tab.)


Clenbuterol from Hilma Biocare is well known as a powerful supplement for weight loss and fat burning. Used both by athletes during preparation for competitions and subjects who do not take steroids as an effective means of weight loss, it remains one of the favorites for weight control. It is classified as an agonist of 2-adrenergic receptors, and not as an anabolic steroid. It is used in medicine for the treatment of impaired breathing, has a broncholytic and secretolytic effect, causing positive chronotropic and inotropic effects.



Using Clenbuterol, athletes can improve their physical performance and effectively lose weight. You have to get used to Clenbuterol, so start with a small dose of 40 mcg, increasing it by another 40 mcg until the optimal dosage is established. Do not exceed the dose of 160 mcg per day and do not drink alcohol. Use Clenbuterol in the morning to avoid insomnia.

Mechanism of action of Clenbuterol

Being a beta-2 agonist, clenbuterol acts as a fat burner by binding to type 2 beta receptors in adipose and muscle tissue of the human body. After clenbuterol binds to the receptor, a cascade of biochemical reactions is triggered, which lead to an increase in the synthesis of cAMP (cyclic adenosine monophosphate). cAMP, in turn, activates enzymes that mobilize fatty acids from adipocytes (fat tissue cells).

When clenbuterol acts on beta-2-adrenoceptors of the presynaptic membrane, the release of norepinephrine and adrenaline, which have a powerful fat-burning effect, increases. Clenbuterol increases the level of basic metabolism by 20-30% from the initial level.

The unique feature of clenbuterol is that it is not only a powerful fat burner, but also has a pronounced anti-catabolic effect, protecting muscles from destruction, which is very important during weight loss and drying in bodybuilding. In the studies, it was established that the anti-catabolic effect of the drug is due to the blocking of Ca2+-dependent and ubiquitin-proteasome proteolysis.

Clenbuterol course: weight loss or drying

In men, the recommended dose of clenbuterol for drying and weight loss is 120-140 mcg per day. In women, the average dose of clenbuterol for drying and weight loss is 80-100 mcg per day. The course of clenbuterol has its subtle features, which must be strictly followed to avoid side effects.

The duration of the course of clenbuterol is usually 2 weeks, then habituation (tolerance of receptors) is developed and the effectiveness decreases. After that, it is necessary to take a 2-week break using ketotifen, without it the break is useless, and then repeat the course, without ketotifen the break should be much longer.The need for a break was scientifically proven back in 1990: desensitization of beta-adrenergic receptors develops due to receptor phosphorylation and other biochemical modifications at the level of secondary messengers (kinases, G-proteins, etc.). It takes several days to update these structures.

The duration and effectiveness of the course of clenbuterol, as it was said, can be increased due to the inclusion of ketotifen. Sometimes, to prevent the adaptation of receptors, a pulse course is recommended – 2 days of reception, 2 days of rest, but this scheme is less effective.

Do not forget to take a sufficient amount of protein, BCAA and other cortisol blockers during the cycle, this will significantly improve the result. Follow the appropriate diet for weight loss or drying.

Side effects

The most common side effects attributed to clenbuterol are increased blood pressure, insomnia, tremors, nausea, excessive sweating, and irregular heartbeat.

Special caution should be exercised when taking Clenbuterol together with other drugs that affect blood pressure and heart rate.
