UFC 101 main event B.J. Penn says he believes Georges St. Pierre uses steroids

UFC 101 main eventer B.J. Penn told Kevin Iole of Yahoo Sports earlier this week that he believes Georges St. Pierre uses steroids. "It’s just my opinion that he uses steroids,” Penn said. “That’s it. My opinion. I do believe it. I can’t hand you any proof, but that’s my opinion.” To read the full interview, visit MMATorch.com.

Powell's POV: Penn would sound more credible if he suggested that GSP uses HGH rather than steroids. I'm not saying GSP uses either performance enhancer, but he is tested for steroids, whereas the fighters are not tested for HGH at this time. Penn headlines tonight's UFC 101 show with a fight against Kenny Florian.
