Thats extreme, 6gs is alot but at 21 hes not the only guy doing it. How do you think the top guys get to where they are??? they do not wait until they are 35+ and then start ramming it all in, its years and years of substance abuse that gets you there in the first place. There is a well known IFBB pro who used to train in my gym who has made the trip over to the states to make a living as a pro, hes 26 now.....been MASSIVe since he was about 18....you figure the rest out.
