Madmick, Ben Johnson was framed. I don't wanna start a whole convo about this and hijack a thread but check out the book "Speed trap" (I think thats the name) by Ben Johnsons coach. Everybody should read it. Its a great book about athletes and drugs and what happened to ben.
In relation to Ben, he had pure stanzanol in his urine which is impossible (It gets broken down into something else). Plus he didn't like winstrol (he used it only once in a while, it made him stiff) and he knew exactly how long it would take to get out of his system. He didn't take it anywhere near the testing date. He never claimed not to juice, but he didn't take what he tested positive for, hence someone framed him.
