While I still think Mentzer was a very smart individual and waaaaay above average in that respect for a bodybuilder, I still must take into account that he took AAS. Without the drugs, he would likely have been a good natural. With them, he was a great competitive bodybuilder. He freely admitted taking AAS but I do not recall him ever quoting his dosage/frequency rates but again, Mike Mentzer was a great competitive bodybuilder in a time many think was the golden era for not just AAS enhanced bodybuilders but all of competitive bodybuilding.
It would be nice if there were a return to sanity. And yeah, I realize using the word "sanity" in a thread about Mike is a bit of a dichotomy.
Brooks Kubik is another author on training that thinks like Mentzer in that hard, infrequent training is the way to go. His concern is primarily strength training and I can't fault him on his choice but he also speaks of size and strength. Bodybuilding is more of an afterthought to him, if it is a thought at all.
