Tell that to Bonds who only became once in a generation after he took them. PED's made multiple once in a generation players (Bonds, Sosa, ARod). None of those guys would have been that good without them. Holy smokes are you comically wrong about this. What's comical are the number of home runs that Bonds and Sosa hit right when they began taking PED's. The frequency of their homers is directly caused by taking them. You have no idea when Sosa started using PEDs. We do, however, know when Bonds started; after that year he had an insane season where he hit 73. His other near-full PED years? 49, 46, 45, 45. Some other Bonds' HR totals pre-1999? 33, 34, 46, 37, 33, 42, 40, 37.
