I will give Mike this. He is incredibly strong and has been in shape for so many decades. He can bench, deadlift, squat and shoulder press a ton of weight without having the powerlifter body. If he is using it must be a low amount than pro bodybuilders cause nobody could heavily juice for as long as he has been in shape. He's also in shape year round. Hell, even the top Mr. Olympia contestants look like crap 4 months after the contest.
