strongest bodybuilder of that era was chris cormier,what you want to check on is 3 bodybuilders that hung together in yates era,early yates era,one was a veteran from the 80s that still competed into the 90s the other two started out low placings then dominated the sport,they learnt basics of hormones from the veteran, one made big improvements right in middle of yates reign,the last one was genetically better than the other two and ended up more successfull,it is obvious that the one in the middle is gh15,he was smartest just didnt have genetics of 3rd man,also they got lot of help from fella that was not competive bodybuild, but knew lots about hormones.
