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.
Efinopegdutide
Human trials have shown meaningful weight loss and improvements in hepatic steatosis biomarkers. It remains a research compound with ongoing development in metabolic disease.
