the left guy is obviously pharmaceutically enhanced - you all know who he is - the guy to the right is natural. Taken in 2004 the morning after the Arnold Classic.
I know both guys and thought this would be a perfect example of a challenging Adam. The guy to the left is ON while the guy to the right is not. Both have extremely low body fat precentages... can't be more than 3-5%. Since TA claims to be at such a level this is how his waistline ought to look these days.
