So apparently it was printed that BJ Penn said that GSP uses steroids, but they're now retracting it.
"To all of our readers, MMA fans and supporters of BJ Penn and Georges St. Pierre: In our current issue of FightSport Magazine, we printed incorrect statements by BJ Penn in the article regarding George St. Pierre's involvement with steroids.
This was a serious mistake. FightSport Magazine sincerely apologizes to George St. Pierre and BJ Penn for this error. For further comment, please visit BJPenn.com to hear what BJ has to say."
