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.
CJC-1295
CJC-1295 has good pre-clinical and early clinical data. The DAC variant shows sustained GH elevation for days. Often combined with GHRPs for synergistic GH release.
