I know nothing about EPO doses, but I'm guessing 7600 i.u.'s is insane. Do you know anything about endurance athletes and EPO Coach? What would a cyclist take?
That's nothing crazy. Anemic patients will get 8,000iu/day.
If you want higher blood count you simply take more and it keeps working.
What is dumb is BBers taking huge cycles which already boost blood. Then taking EPO on top. That will kill you as many cyclists died from thickening blood. What most.probably don't know is those pros were taking huge amounts of aspirin to prevent thickening blood from stopping their heart to the point their alarm clock is going off during the night to take more and not die!
