Dave Drapper was popular in the 60's and was on the cover of Muscle builder and Mr.America(Joe Weider magazines) along with Larry Scott . He was vascular and separated back then. In 1985 after HGH had it's curse lifted (about been linked to dead people from Africa ,where it was taken from the people's brain). I believe then the body builders started to slowly get interested in HGH . I believe that Saizen was one of the first names that emerged. Dave Drapper had already been vascular at that time . Probably Winstrol,Primo,Anavar,and Masteron and good genetics.
