Overview
EPO (Erythropoietin) is catalogued here as a approved hematopoietic hormone and graded at the "Approved medicine" evidence tier. This compound exists as an approved medicine in at least one major jurisdiction. Approval applies to specific, labeled indications and to the regulated product — not to compounded or research-grade copies.
Recombinant erythropoietin is an approved medicine for anemia of chronic kidney disease and related conditions — and one of the most infamous doping agents in endurance sport.
Mechanism of Action
EPO activates receptors on erythroid precursors, increasing red-cell production and oxygen-carrying capacity.
Research and Evidence
Extensive registrational evidence in renal anemia and oncology support approved use.
Safety and Side Effects
Non-medical use raises thrombotic and cardiovascular risk; EPO is prohibited in sport under the erythropoiesis-stimulating agent class.
