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.
GPE
Preclinical studies suggest GPE can reduce neuronal damage and support plasticity-related pathways in the brain. Research interest centers on hippocampal function, which links it to learning and memory paradigms.
