I am no expert, but EPO doping can be lethal ,"hyperviscosity," or thickened blood which can cause a heart attack, what I have read is that more than a few have died in their sleep due to thickened blood. What this means is that if a clean cyclist is faced with the choice of being disadvantaged by the 5 - 15 % advantage that EPO doping affords or he EPO dopes and potentially risks heart attack. I am the last person to get on his high horse about drug abuse BUT the reason they ALL take drugs is because you can't ever win if even a few take them.
