EPO is more of an endurance sport thing. You’d see it in stuff like cycling and long distance running, not so much in football. The hematocrit spike also goes away within a few weeks as the injected red blood cells don’t replace themselves whereas the hematocrit increase from steroids is a bit more permanent and requires bloodletting.
