LMFAO he was not a juicer dude. You can tell by the way he worked out. Roids help recovery time specifically. If he did juice he would do those 4 set per body part with lots of that "more is better" philosophy. It would be a waste and you would see much less results doing the philosophy he has written up.
Sorry, but you are one of those guys that sees someone huge and labels him a juicer. Look at his site, look at his philosophy, everything he wrote was anti-roid, all natural, and his whole workout was based on all natural. It would be a waste of time, money, and health for him to use roids based on the routine he had and was known to use his whole career.
