Quick Summary
Dual GLP-1/GIP agonist — the most effective weight loss peptide available
Also called: Mounjaro, Zepbound
What is Tirzepatide?
Tirzepatide is a first-in-class dual GIP (glucose-dependent insulinotropic polypeptide) and GLP-1 receptor agonist developed by Eli Lilly. Clinical trials demonstrated unprecedented weight loss of up to 22.5% of body weight in the SURMOUNT-1 trial, surpassing semaglutide's efficacy. Approved as Mounjaro for type 2 diabetes and Zepbound for chronic weight management.
How It's Made
Tirzepatide is a synthetic 39-amino acid peptide that acts as a dual agonist at both GIP and GLP-1 receptors. It incorporates a C20 fatty diacid moiety that enables once-weekly dosing through albumin binding, similar to semaglutide's mechanism of extended half-life.
