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.

GHRP-6

GHRP-6 has solid pre-clinical and clinical evidence for GH stimulation. Well-characterized pharmacology. More appetite stimulation than Ipamorelin due to ghrelin receptor activation.
