A dual GLP-1 and GIP receptor agonist. The strongest weight-loss molecule available, ahead of semaglutide in head-to-head trials.
Tirzepatide activates two gut-hormone receptors at once, GLP-1 and GIP. The result is stronger appetite suppression, slower digestion, and better blood-sugar control than single-agonist GLP-1s.
It is the same molecule as Mounjaro and Zepbound, the FDA-approved brands, and reached up to roughly 21 percent body-weight loss in the SURMOUNT-1 trial.
Peptides are shipped freeze-dried for stability. You reconstitute with bacteriostatic water before use.
The certificate matches the exact lot you receive, with its own lot number and test date.
Purity by HPLC, identity by mass-spec. We require both before a product goes live.
Random vials go to an outside lab. If the numbers do not match the COA, the batch is pulled.
Tirzepatide activates both the GLP-1 and GIP receptors at once, a mechanism no single-agonist molecule matches.
In the SURMOUNT-1 trial, participants on the 15 mg dose lost 20.9% of body weight over 72 weeks.
In the SURMOUNT-5 comparison, tirzepatide outperformed semaglutide on percentage weight change.
| What you get | Purivial | Typical vendor |
|---|---|---|
| Batch-specific COA | Every order | Reused or none |
| HPLC purity | 99%+, published | Sometimes |
| Mass-spec identity | Required | Usually missing |
| Independent re-test | Random vials | In-house only |
| Verify it yourself | Public lookup | No way to check |
Every lot is HPLC and mass-spec tested and gets a dated Certificate of Analysis before it ships.
Lyophilized, packed cold, and tracked to your door. Free shipping over $75.
Look up the batch and verify the exact purity and identity of what you received, yourself.
Yes. Every batch ships with a Certificate of Analysis showing HPLC purity and mass-spec identity for that exact lot, plus an independent report you can verify yourself.
Mass spectrometry confirms the molecule matches the label, and HPLC confirms purity at 99 percent or higher before the lot is released.
It ships as lyophilized freeze-dried powder, cold and tracked. Store at 2 to 8 degrees Celsius and reconstitute with bacteriostatic water for research use.
No. It is sold strictly for laboratory and research use, not for human consumption. Statements have not been evaluated by the FDA.
