naaaaaa mate personally i don't believe any of that - i think he just trains bloody hard, lives correctly and has a world-class support team around him. And the successes he's had are due to that and not any magic potions.
probably not many more fights now before he goes full time politician so let's all just appreciate someone at the very top of their game.
(can't say that I'm super excited about seeing the Pac vs Moseley fight though, but still...)
