The guys joints are very small which is great for bodybuilding and giving an illusion of being bigger then you really are...If I was to guess if he uses anything I would say he does but only because of the size of his neck...If he wasn't using and he dieted down, his neck would thin out even if he trained it alone...His neck is a dead give away to me because his joints are so small...And I won't even get into that fact that you could you could watch a double feature on that drive-in movie type forehead...
