@nony - I agree that for athletes, it’s probably not worth it.
However, for anemia patients who already suffer a debilitating condition, they have to weigh the erythropoietin side effects with the price they will pay if they do nothing.
The only concern I would have is to make sure that side effects are not handled with more drugs. If a patient develops high blood pressure as a result, for example, does he then take blood pressure medication? If he takes blood pressure medication, does he then take another drug to offset that drug’s side effects?
You see what I mean. I’ve known people who have taken a whole “basket” of drugs simply to compensate for one drug’s ripple of side effects.
