There are millions of people on steroids. They are in every sport. There are a handful of guys in YOUR gym that are on steroids. To be a Silva or Belfort or Brock or Gracie, you have to be better than everyone, mentally and physically, and that comes from the person, not the roids. You can give 10,000 people roids, give them a training regiment, and still only one is going to come out on top. Roids simply keep a guy that is number one, a bit more time staying at number one. He already has the skills and strengths to be there, but the roids help to keep him prime. You cant just go juice and then become a world champion.
