Research Overview
Secretin
Secretin is a classic GI hormone with extensive physiology literature and established diagnostic use. It remains important for studying pancreatic secretory function, biliary responses, and duodenal feedback.
Epoetin Alfa
Human studies in anemia and performance-related settings show that increasing red-cell mass can improve aerobic capacity and endurance. It remains heavily regulated because excessive erythropoiesis raises thrombotic and cardiovascular risk.
