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.
BYM338
Clinical trials showed meaningful increases in lean mass, with mixed functional outcomes depending on population and endpoint. The antibody remains one of the best-documented receptor-blocking approaches to muscle anabolism in humans.
