The accusations may be referenced, but AFAIK he's never admitted PED use, nor was he ever found guilty of a doping violation by any authority
Did you read the source? He DID admit taking PEDs.
You don't want random people accusing you of something without ACTUAL PROOF of wrong-doing, do you?
By random, if sports officials, teammates or coaches say I cheated then that isn't so random. I wouldnt post idle speculation but pointing out that an athlete suspected me (like it sounds like Allyson Felix did about someone, prob Jeter, to Piers Morgan or if the German federation had files that say I cheated then I think that is serious enough to post (and document).
