Three incretin receptor agonists, three different levels of receptor engagement. The figures below are the reported peak weight reductions from published clinical trial programs.
| Compound | Receptors targeted | Reported peak weight reduction | Regulatory status |
|---|---|---|---|
| Semaglutide | GLP-1 | ~15β17% | Approved |
| Tirzepatide | GLP-1 + GIP | ~20β22% | Approved |
| Retatrutide | GLP-1 + GIP + glucagon | ~24β29% (28.3% at 12 mg in TRIUMPH-1) | Investigational |
Adding the third receptor adds real effect, but less than the second one did β the returns per added receptor are diminishing. The full breakdown of the TRIUMPH Phase 3 readouts is in our article: Retatrutide vs Tirzepatide vs Semaglutide: one, two, or three receptors.
Research use only. This comparison summarises published clinical trial results. It is not medical advice and makes no efficacy or safety claim. Retatrutide is investigational and is supplied by Universe Peptide strictly for in-vitro laboratory research.
Universe Peptide supplies research peptides and laboratory biochemicals to researchers, universities and analytical laboratories. Every compound in the catalog is third-party tested, ships with a Certificate of Analysis (COA) for its lot, and is supplied strictly as a laboratory research compound β never for human or animal use.
The catalog covers the compound families researchers ask for most: GLP research compounds including Retatrutide, and research peptides such as TB-500, GHK-Cu, Epithalon, Semax, Selank, MOTS-c, SS-31, Tesamorelin and CJC-1295/Ipamorelin. We also stock laboratory-grade reconstitution solution for preparing lyophilized powder at the bench.
What we publish alongside the catalog matters as much as the catalog itself: mechanism explainers, regulatory coverage and comparison articles written from primary sources β FDA meeting records, published trial readouts and peer-reviewed literature β with the evidence limits stated plainly. If the human data for a compound is thin, our articles say so.

What researchers ask most often about our compounds, purity testing and shipping.
Research peptides are short chains of amino acids supplied for in-vitro laboratory and analytical work. They are used by researchers to study mechanisms, pathways and binding activity. They are not medicines and are not supplied for human or animal use.
It means the compound is sold exclusively for laboratory experimentation. It is not an FDA-approved drug, it is not a dietary supplement, and it may not legally be administered to humans or animals. Universe Peptide is a chemical supplier, not a compounding pharmacy or an outsourcing facility.
A COA is the third-party laboratory report for a specific production lot. It documents identity and purity, typically by HPLC and mass spectrometry. Every lot we ship has a COA, and the reports are published on our Analysis page so you can check the compound before you buy.
Our research peptides are tested at 99% or higher by HPLC. If a batch does not meet the standard, it does not ship. The measured value for your specific lot is on the COA.
We ship from the United States. Orders placed before 12:00 PM ET, Monday to Saturday, typically dispatch the same business day; orders after the cutoff go out the next business day. Shipping is a $15 flat rate and free on orders over $250, sent via FedEx or UPS, with USPS for PO Boxes.
Lyophilized (freeze-dried) powder is stable at refrigerated temperature and should be kept cold, dry and away from light. Once reconstituted, the solution has a much shorter usable life and must be refrigerated. Storage conditions for each compound are stated on its COA.
Reconstitution is dissolving the lyophilized powder into a liquid so it can be handled in the laboratory. We supply a laboratory-grade reconstitution solution for this purpose. Our guide on reconstituting lyophilized peptides walks through the procedure.
