Mechanism & published research
Acts as an agonist at GLP-1, GIP, and glucagon receptors simultaneously; the added glucagon activity is the primary point of research interest versus dual agonists.
Studied for significant body-weight change over 48 weeks in a phase 2 program.
Triple-receptor pharmacology characterized in receptor-binding and preclinical models.
Descriptions summarize existing published research and are not claims about outcomes from use. Every citation states its study type and population.
How it compares
| Versus | Attribute | Note |
|---|---|---|
| Tirzepatide | Receptor targets | Retatrutide adds glucagon-receptor activity to the GLP-1/GIP profile. |
| Semaglutide | Mechanism | Semaglutide is GLP-1 only; retatrutide is a triple agonist. |

Reviews
Reviews are collected post-delivery and screened to exclude any human-use or dosing-outcome claims before publication. They speak to product quality, shipping, and COA accuracy.
“99.2% on the certificate and the reconstituted solution was water-clear with no particulates.”
“The lot on the vial matched the COA in the hub and verified on the lab portal. That check is why I keep ordering.”
“The batch on the vial resolved on the verification page instantly. Consistent with what the product page listed.”
