The UCI reports that’s the level of clenbuterol found in Pistolero’s system
Clenbuterol is available for veterinary use to treat horses with respiratory problems. It’s a bronchodilator like the more familliar albuterol / salbutamol inhalers used by asthmatics all around the world, but more stronger and with scarier side effects. It also has the interesting property of increasing muscle-to-fat ratio in humans and animals. In the United States, Clen is illegal for human use, but is approved for treating asthmatic horses through injection.
Alberto Contador’s claim that he ingested the drug through eating meat is at least plausible — the drug is used ilegally in livestock to bulk them up in the same way as bodybuilders, though news reports of clenbuterol animal doping all seem to come from China. One has to wonder how Contador knows it came through his meal if he’s as innocent as he claims. Maybe his team doctor knew how to get the right kind of enhanced steak for his cyclists?
Polish sprint canoer Adam Seroczyński was disqualified for taking clenbuterol after finishing fourth in the K-2 1000 m event at the 2008 Summer Olympics in Beijing, and Chinese cyclist Li Fuyu tested positive for it at the Dwars door Vlaanderen race in Belgium on March 24, 2010.
