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.
Leuprolide
Leuprolide is one of the best-studied GnRH analogs in reproductive medicine and assisted reproduction. It produces an initial flare followed by receptor desensitization and reduced LH/FSH output.
