Steroids have been used for years, in several different sports, even the Olympics... They are still used today in sports in the form of cortisone shots, which you see fairly often with older players... I think steroids can be used effectively, within' the "pro sports world" if younger athletes were to realize that they don't need them... You have higher testosterone levels when you're younger, and they start to decline at a certain age... Steroids help replace that...
