I was pretty up on all that EPO & blood doping stuff a couple of TdFs ago, but I'm no longer fluent. Also, I'm not of the scientific persuasion, so I am hampered by my extreme idiocy.
But you know, that wacky thing that just came to me about him possibly having become a chimera after treatment with allogeneic natural EPO back in his cancer days and having cells now which are different genetically (& which would therefore allow him to do allogeneic epoetin instead of synthetic all he wanted because as a chimera he's supposed to have heterogeneous cells, so it wouldn't be evidence of doping as it would for everyone else) sure sounds like.... a great script idea for House, maybe.
But with all their unethical sources at the French drug testing labs, I think we would have all heard about it from L'Equipe if Lance Armstrong was a chimera, lol. ;-)
There was an episode of House on over the weekend where a bike rider had a tumor in which the treatment for anemia was blood doping and sleeping in a hyperbaric chamber both of which the rider was doing. He was “doping” but only getting back to “normal”.
