Revise: Performance-enhancing drugsErythropoietin (EPO) is a hormone that stimulates red blood cell production. Athletes may misuse a synthetic version to increase the blood’s oxygen-carrying capacity and improve endurance. EPO and GH are both peptide hormones, but their intended performance effects are different: EPO improves oxygen transport, whereas GH promotes tissue growth and recovery.
