Clenbuterol for weight loss and fitness

Clenbuterol can not only increase muscle mass, but also reduce body fat. In addition, it works in the body for up to six days (detectable traces may last longer). Because of these characteristics, it is often used as a weight-loss supplement or to improve exercise ability.
People who take clenbuterol to lose weight or exercise often use anabolic steroids or growth hormones.
Although many studies have been carried out in animals and livestock, there are very limited studies on the efficacy of clenbuterol as a weight-loss or performance enhancing agent in humans:
According to researchers from reliable sources, clenbuterol stimulates muscle growth and repair while preventing muscle atrophy in mice and rats.
Studies from reliable sources have shown that increased muscle growth comes at the expense of reduced adipose tissue.
A study from horses found that long-term use of large doses of clenbuterol increased the expression of genes related to various muscle components and fat metabolism.
Although there is little evidence that clenbuterol is a performance enhancing drug, it has been banned by the World Anti Doping Agency (WADA).
