Why wasn't Frank Mir able to head kick Mark Hunt to oblivion? Why didn't it make his jaw bones and muscle tough like steel, and protect him from a one punch KO? Frank Mir is legit BJJ black belt with one punch KO power, and a guy who beat Brock Lesnar, so why wasn't he 20% stronger and faster to beat a slow and flabby Mark Hunt? Steroids don't work when it comes to fighting. In any given match-up, your chances to win with or without steroids is about equal. MMA is not track & field where you are racing for split seconds. It takes a lot more to beat your opponent, and if you don't have it, you are not going to get it by using steroids. If I am wrong, show me some evidence that contradict my position.
