Fernando had Clenbuterol in his system and that is a KNOWN popular steroid in America.
In the below article Fernando states "I must have digested the substance inadvertently while training in Mexico." His argument is less rock solid than Shelby as he had apparently no idea what he ate in Mexico that was tainted while Shelby was able to pinpoint the exact food from a food truck.
My question is, why do they clear one athlete and not another when they are both claiming that they had a failed test by the exact same means? It makes me think that they must have had some inkling that she was doping even prior to this test.
