Frank had amazing genetics. He wasn’t natural, however he didn’t do the amount of drugs the guys just after him used. These days the 50 year old bodybuilders are dropping dead like flys. 3 or 4 this month. I used everything myself, I didn’t abuse any of it. Frank was smart. The guys who were all natural from his era look like swimmers.
Didn't one or two of the swimmers go on to play Tarzan, last i recall he and Jane are still swingin
In terms of Zane i'll defer to your position that he was enhanced because i believe you know more about the sport, and it's secrets, than i do
