Usain Bolt could be clean, he could also be using/have used drugs, until proven otherwise its not fair to him to label him a cheater.
Winstrol is a pretty mainstream drug for sprinters, not alot of weight gain, clears quickly, and very popular in power/speed sports.
i thought winstrol made your tendons brittle? i figured more athletes(who can afford it)would use anavar
lol, it makes your penis shrink too right? tendonitis is alot different that "brittle tendons", and athletes have been using winstrol in sports for years and years, especially sprint oriented sports. Anavar is very popular amoung females figure/supposed to be "natural" bodybuilders.
Anyway, I dont like talking about steroids period, I dont condone it and I dont believe its necessary in any sport other than bodybuilding.. Ive said this every time this subject comes up, but there are 1000x more frat boys in your local gym JUICED TO THE GILLS, weak as dogshit, and good at absolutely no form of anything resembling athleticism, than there are elite or good athletes on drugs.
