that wasn't an attack on you guy. but americans do not have the culture, just like with soccer! and , you know in ALL sports, guys take drugs. not for competition but for training. you take drugs when you train: no risk of beein' caught and you enhance your abilities for the competition where you 'll stop drugs!!!
moreover, he (and others) maybe has something not forbidden coz' known by only him and that you can't find for now. maybe in few years people will say: ho, yes, he was taking these drugs. don't you think so???
