Dual GLP-1 / GIP receptor agonist. FDA-approved as Mounjaro (T2D) and Zepbound (obesity).
Tirzepatide hits two incretin receptors: GLP-1 and GIP. The dual agonism produces a larger weight-loss and glycemic effect than GLP-1 monotherapy at comparable doses. Marketed as Mounjaro for type 2 diabetes and Zepbound for obesity by Eli Lilly.
Standard escalation schedule starts at 2.5 mg weekly, increasing every four weeks through 5, 7.5, 10, 12.5, and 15 mg. The Surmount trials used this schedule with optimal weight-loss outcomes at the 10–15 mg range.
Tirzepatide is the most-stocked compound across the audited vendor pool — every major research vendor lists it, which makes it the natural starting point for cross-vendor purity comparisons. Cross-lab agreement on tirzepatide tends to be tight (<1 percentage point) at the top vendors and looser (2–4 points) at the bottom of the pack.
