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.

Capromorelin

Research consistently shows capromorelin activates the ghrelin receptor pathway and increases food intake. Human development has been less prominent than veterinary use, but the compound remains a relevant GH secretagogue prototype.
