Clenbuterol is a compound that belongs to a class of drugs called beta2-agonists. Drugs in this category can cause dilation of the bronchial muscles. Beta-2 agonists are often used to treat asthma.
In addition to being used to treat asthma, clenbuterol has become popular as a weight-loss supplement. This is because of its effect on muscle growth and fat reduction.

Weight loss and performance enhancement
Clenbuterol has been shown to increase muscle mass and reduce body fat. In addition, it remains in the body with an active effect for up to approximately six days after consumption (detectable traces may remain longer). Because of these properties, it is often used as a weight loss supplement or to enhance sports performance.
People who take clenbuterol for weight loss or performance enhancement often also use anabolic steroids or growth hormones.
