Research Overview
Cholecystokinin-8
CCK-8 is a canonical gut hormone fragment with extensive documentation in digestive physiology and appetite control. Sulfation of the tyrosine residue is important for high-affinity receptor activity.
Pemvidutide
Clinical studies have reported dose-dependent weight loss and favorable effects on liver fat and transaminases. It remains investigational and is not approved for obesity treatment.
