Why Buy Tirzepatide 15mg from Peptide Scientists
Tirzepatide is the same active compound found in Mounjaro and Zepbound — but for a fraction of the price. Buying it as a research peptide costs ~$10/mg vs hundreds per dose at the pharmacy.
Our Tirzepatide is sourced from Phiogen (Iceland) with ≥98% HPLC purity verification. Every vial ships with full QC documentation.
The 15mg vial is the SURMOUNT-1 maintenance dose and the standard endpoint of all weight-loss escalation protocols. One vial covers a month at peak dose.
About Tirzepatide 15mg
Tirzepatide is a 39-amino-acid synthetic peptide with C20 fatty diacid lipidation, enabling once-weekly subcutaneous dosing via albumin binding (5-day half-life).
It's a dual agonist of GLP-1 and GIP receptors. The GIP component is what differentiates it from semaglutide — driving additional fat redistribution from visceral to subcutaneous depots and attenuating GLP-1-mediated nausea.
Phase 3 SURMOUNT trials demonstrated −22.5% mean body weight loss at 72 weeks (15mg dose). Cardiovascular outcomes data from SURPASS-CVOT showed superiority over semaglutide for MACE reduction.
