We are never, ever, going to know a complete list of who used what performance enhancing drugs. IMHO - usage was widespread and was not limited to a handful of superstars. Marginal players were made good, good ones great and great ones turned into legends. Those legends caught turned into pumpkins.
I really don't care about it anymore, time to move on. I would put them in the HOF. They were still the best of their era, the steroid era, and most people were probably using something some of the time anyway.
