Research Overview

HGH Fragment 176-191

This 16-amino-acid fragment specifically targets adipose tissue via beta-3 adrenergic receptors. Works through a GH-receptor-independent pathway, explaining selective fat-loss properties without growth-promoting effects.

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.
