Many are aware of the history made at the Seoul Olympics in 1988 when Ben Johnson ran the 100 meters in 9.79 seconds. Now that requires a lot of hard lean muscle performing at its peak potential! (Have you ever looked at the legs on a sprinter?) This amazing performance made him the fastest human ever. To say the least this was a proud moment in Canadian athletic history that quickly turned into a nightmare. Less than 62 hours later, Olympic officials entered Johnson's room and walked out with his gold medal. Ben Johnson had tested positive for illegal AAS (Anabolic-Androgenic-Steroid) use. He tested positive for a well-known lean muscle promoting AAS called Winstrol. The Canadian sports establishment was scandalized. Johnson lost several million in endorsements and sponsorship fees, and he was suspended from competition for two years. But no one will deny that Ben Johnson did show amazing muscular performance!
