Alright, right now everyone thinks that Insane Bolt is not using any drugs. This is obviously wrong. There is no way that one man can be that far ahead of every other sprinter in the world.
One day some news will come out talking about some inovative drug and how previously it was undetectable, around this same time Bolt will go from running his 9.7X's to 10.05s.
He is obviously on some sort of drugs. Everyone remembers how he set his WJR 19.93 and then it took him a few years to even challenge that mark again. He tried doing it naturally, realized that he couldn't, then started doping.
This will more than likely be proven to be correct.
