bodybuilders, on the pretty large scale, started to use GH in the early to mid 80s..........you can see the change around the time haney started winning olympias..........at first growth hormone was synthesized from cadavers, and im not exactly sure what year the synthetic version was invented, or when people made the switch to this synthetic version........im speculating around the 88-91 timeframe.........then of course.......it was far more available.
but, i could be off...............there have also been reports of HGH, becoming available almost a decade earlier.......but at this point it was supposedly very difficult to obtain, so only the high eschalon guys, like arnold, would be able to get their hands on it......likewise, there are alot of rumblings that arnold might of had this available to him as early as the late 70's..................
milos sarcev, who one may, or may not believe told a story just last week that one time in the 90s, he saw frank zane at a bodybuildign show, and kind of joked with him "I'll bet guys from your era wish they had access to the drugs we do now-a-days"................to which zane replied, with a wink, "what makes you think we didnt"
but the short answer would be HGH use became the standard in bodybuilding in the late 80s.
