Remember one thing, these guys make serious money and have the best trainers, cooks, stregnth coaches, etc. They can change their physiques dramatically for a role with proper diet and exercise. As far as Mickety Rouke in the wrestler, he pretty much admitted using. JAKE GYLENHALL IS JAKED, I think he cycled. You never know, but those guys can get whatever they want. I think Ed Norton said he ate like 7 meals a day high protein and heavy weights. He said he couldn't tell you what a steroid looked like...PEACE !!
