Yes it does make a difference when blood leaves the body. It is not just "stored and re-introduced," but the RBCs are concentrated (as others have said), so it's a very big difference.A blood transfusion that's deemed "medically necessary" is allowed, but the existence of loopholes doesn't make a law wrong. Similarly, Lance Armstrong took normally "illegal" substances that were allowed during his recovery from cancer. (Maybe someone knows the details?) It's possible then that his bout with cancer turned him into the Tour de France champion. These disturbing possibilities don't make blatant cases of cheating, e.g. blood doping, OK.

Hey Stupid F***,
