Is clenbuterol legal?
Not legal advice: In the United States, clenbuterol is not approved for human use. It is only allowed for use in horses, and is also illegal to be used in any food-producing animal. The drug is legal in certain countries as a prescription bronchodilator for asthma sufferers.
The drug has been abused by athletes as it has the ability to increase lean muscle mass and reduce body fat. It is also listed as a performance enhancing drug by the World Anti-Doping Agency and the International Olympic Committee.
Guillermo Mota, a relief pitcher for the SF Giants, was just suspended for 100 games after testing positive for clenbuterol. He will not be eligible to play until late August 2012.
