most of these guys with their procard have nutritionists, coaches, doctors etc. i'd be surprised if even half of them knew what the hell they were taking. also these guys may shoot a lot of gear and are walking laboratories, but they are still genetic freaks and are in the game because of that and their work ethic. also i doubt the regular joe is even interested in or can even afford hgh. some people take Human Chorionic Gonadotropin (HCG) during post cycle therapy (pct), i don't recommend it. great to take during cycle to make pct that much easier.
