There are many roid cheaters who never once have his named mentioned after getting banned and coming back to this game again.
Romero tested positive and then cleared his name. Just because he looked like greek god doesn't mean he's cheating.
There are 7 billion people in this world. And ever increasing. People are born differently, different genetics, environment and TRAINING. Out of 7,000,000,000+ Great combination of all three can not result in someone looking like Romero or move like him?
Romero has been competing in international wrestling for god knows how long and olympics as well, and has never tested positive once in his mma career as well, outside of one case he could prove his innocence.
