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.

Mazdutide

Clinical programs have shown substantial reductions in body weight and improvements in cardiometabolic risk markers. It is a prominent newer dual agonist in the obesity literature.
