Dr. Steve Elliott is a former Scientific Executive Director at Amgen, an expert on the process of creating new red blood cells (i.e. erythropoiesis), and a champion of anti-doping. He dives into what erythropoietin (EPO) is, how it’s made in the body, the impacts of not having enough EPO, and how EPO abuse can enhance athletic performance. We also cover tests developed to detect EPO and recombinant EPO abuse, and the red flags scientists look for to determine if athletes have been doping with EPO.
