Blood doping blood doping. Experimental evidence, however, has shown that cobalamin has no effect on erythropoiesis in the absence of a red blood cell/oxygen deficiency. These results seem to confirm much of what is already known about the functioning of cobalamin. The signaling pathway that induces erythropoietin secretion and subsequently red blood cell manufacture using cobalamin is O dependent. Erythropoietin is only secreted in the kidneys when there is an O deficiency, as such, RBC manufacture is independent of the amount of cobalamin administered when there is no O deficiency. Accordingly, cobalamin is of little to no value in blood doping. More
