NOTE: One interesting fact about erythropoitin is that it is also called EPO, a name that may be more familiar to some of you. Yes, that should bring the name Lance Armstrong to mind. Lance Armstrong confessed to using EPO as a performance enhancing drug strictly for the purpose of raising his red blood cell counts for racing purposes. Basically, he was doing a different and very dangerous kind of steroid. Giving EPO to these racers leaves them vulnerable to dieing in their sleep from the "sludging" of the blood that occurs. It does turn them into superhumans however.
