GLP-1 (glucagon-like peptide-1) receptor agonist peptides are a class of compounds that mimic the action of the naturally occurring incretin hormone GLP-1. When activated, GLP-1 receptors stimulate insulin secretion in response to food intake, suppress glucagon release, slow gastric emptying, and promote satiety through central nervous system signaling. Semaglutide, liraglutide, and the newer multi-receptor agonists like tirzepatide and Retatrutide all work through GLP-1 receptor activation as part of their mechanism.
