What the published Tirzepatide research describes
What it is: A dual GIP and GLP-1 receptor agonist peptide, studied as a once-weekly compound for body-weight reduction.
SURMOUNT-1: In the phase 3 SURMOUNT-1 trial, the highest arm reached a group mean body-weight reduction of up to about 22.5 percent over 72 weeks (Jastreboff et al., N Engl J Med 2022, PMID 35658024 https://pubmed.ncbi.nlm.nih.gov/35658024/ ).
Compared with semaglutide: Semaglutide, a single GLP-1 agonist, reached about 15 percent in its own phase 3 trial, STEP 1 (Wilding et al., N Engl J Med 2021, PMID 33567185 https://pubmed.ncbi.nlm.nih.gov/33567185/ ); the two were not tested head to head in these trials.
Status: Research-grade tirzepatide is not the approved branded product.

How to check a Tirzepatide vial
Match the lot number on your order to TIRZ-260420-A on the certificates page; identity by LC-MS says the compound is Tirzepatide, while the purity figure alone only says the sample is mostly one compound.
Tirzepatide vials ship unlabeled on purpose, so the team confirms your batch from your order number on WhatsApp and sends its published certificate.
