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.
Dulaglutide
Dulaglutide has repeatedly shown small-to-moderate reductions in body weight alongside glycemic improvement in large diabetes trials. It is a useful comparator for GLP-1 receptor agonist effects on appetite and weight.
