GLP-1 Agonist
Also known as: GLP-1 receptor agonist · GLP-1RA · incretin mimetic
A class of peptides that activates the GLP-1 receptor, researched for effects on glucose regulation, gastric motility, and appetite signaling.
GLP-1 agonists include Semaglutide, Liraglutide, Exenatide, and the dual-agonist Tirzepatide (GLP-1 + GIP). They are the most clinically studied peptide class, with extensive RCT data across metabolic research contexts. Engineering differences — fatty-acid side chains, amino acid substitutions — produce radically different half-lives and receptor selectivity profiles.
GLP-1 agonists are being researched for effects on weight regulation, glucose homeostasis, and emerging indications including addiction research and neuroinflammatory signaling. They represent the most developed and regulated corner of the peptide landscape.
