GLP-1 (Glucagon-Like Peptide-1) — Peptide Glossary | RetatrutideCompare

An incretin hormone produced by intestinal L-cells after eating. GLP-1 stimulates insulin secretion, suppresses glucagon, slows gastric emptying, and promotes satiety. GLP-1 receptor agonists (Semaglutide, Liraglutide, Retatrutide) mimic this action.
