We found that cyclist Lance Armstrong was guilty of using EPO on several accounts. Erythropoietin, also know as EPO, is a drug used medically to treat anemia. This advancement in medicine has helped save lives but unfortunately professional athletes, like Armstrong, have used it to help improve their performance. The earliest claims of doping was with Gastone Nencini in the 1960 Tour De France. Around this time athletes would store blood and wait for the body to replace the loss blood. Afterwards they would take the stored blood and inject it into themselves. This would give the athlete extra blood, therefore more oxygen blood cells. EPO made blood doping a lot easier for athletes such as Armstrong. EPO is not a drug in a legal sense.
