Stevie, from a standpoint that one is an easy shortcut and one involves a lot of hard work and so is "morally" superior, then it is indeed a difficult argument to make, although, if the end results are the same (although from what ross and the article he linked to says, they aren't) then I think you could just about make a case for them not being as different as many think. Both would seem to be gaining an advantage by artificially altering something in the body (one by a drug, one by going up high). Anyway, as I said, it's not an argument I would agree with and am just playing devils advocate really.
I guess what I'm really driving at is the other standpoint against illegal drugs of all types - that they're bad for you. Here I think the waters are muddied a bit more because, if increasing the red blood cells in your body over a relatively short time is bad for you (I don't know enough to know if this is true, so would like more information) then presumably it's bad for you if you do that by altitude training as well.
I was just struck by the similarities between what I've read about the goals of taking EPO and altitude training and would like to know what the differences are in effect on the body.
At the end of the day though, I do agree with you.
