Man, I know I'm gonna get flamed for this, but had I not seen his legs, I would say it was a possibility he wasn't on any steroids. Now, natural, no way. He is definitely taking something. That being said, I think he is on something seeing how he has full quads at low body fat, and while having a great build, lighting can do a lot. But, no, if I had to bet I would say that he is hormonized.
