I would personally guess testosterone, hgh , insulin, and probably something like masteron I don't see him taking tren now days. Maybe he does but at his age and his history of steroid use I see his system being pretty taxed already and tren would not be a good thing for him to take. I think a lot of it really has to do with his genetics and his diet. its obvious he is still on something but still I think his diet and genetics is what is making him look so crazy still these days. Im sure he is damn near forced to eat 100% clean after all the years of abuse on his body. I could be wrong im no genius.
