In the beginning Clenbuterol (aka Clen) – was used as a cure for asthma. Nowadays it is a drug of choice among bodybuilders and other athletes owing to its fat-burning properties.
In cutting cycles it is usually stacked with Zaditor (Ketotifen) to quicken the weight loss. It does not belong to steroids, therefore women can use it without the hazard of androgenic adverse effects. Its half-life is about 35 hours
Hur det fungerar
Clenbuterol has affinity to beta-2 adrenergic receptors in fat and muscle tissues. This binding initiate a chain of reactions, which causes buildup of cAMP. In its turn cAMP induces enzymes that initiate lipolysis in fat cells.
The effects of Clenbuterol
- Increases the levels of noradrenaline and epinephrine, both of them are powerful lipolitic agents.
- Enhances metabolism
- Stalls lipoprotein lipase, thus blocking fat deposition.
- Increases the production of thyroid hormones – which also act as fat burners.
- By inhibiting ubiquitin-mediated proteolysis, Clenbuterol provides anticatabolic effect. Thus, it prevents destruction of muscles, which is important for athletes.
- Activation of Crtc / Creb proteins causes anabolic effect
- Enhances stamina and strength
- Increases mental activity
- Decreases appetite
Dosering och användning
The common dosage for men is 120-140mcg/day. Women should take it at the dosage 80-100mcg/day.
The length of a cycle is two weeks. After that period the tolerance occurs and efficiency is reduced. Then you have to take a two-week break using Zaditor, and then repeat the cycle. If you don’t use Zaditor, you have to prolong the recovery period.
Note: For optimal results you should follow a weight-losing diet, take BCAA and cortisol blockers during your cycle.
