so which is it? do steroids decrease the length of your career or extend it? yesyesyes. if a player can't stay healthy, people say the steroids killed him. if a player never gets hurt, they say the steroids make him super strong. it seems unlikely that both would be true. Seems quite likely that not all users are taking the same thing, and not all bodies respond exactly the same way. "Steroids", in the general sense, can lead to your body breaking down, but they can also help you recover from normal wear and tear, and prolong your peak. so if steroids could be doing either, why does it make sense to try to use a players longevity or inability to stay healthy as evidence for steroid use?
