Retatrutide vs Brenipatide
An investigational GIP/GLP-1/glucagon triple receptor agonist. A once-monthly dual GIP/GLP-1 agonist aimed at the brain's reward circuitry rather than the scale. Side by side: type, evidence tier, receptor, molecular weight, and half-life — the same fields as each monograph, rearranged so the engineering difference is visible.

Common questions
- What is the difference between Retatrutide and Brenipatide?
- Retatrutide is an engineered analog based on Glucagon-like peptide-1; Brenipatide is an engineered analog based on Glucagon-like peptide-1. Retatrutide signals at GIP + GLP-1 + glucagon receptors; Brenipatide signals at GIP + GLP-1 receptors.
- How do the half-lives of Retatrutide and LY3537031 compare?
- The reported circulating half-life of Retatrutide is ~6 days; Brenipatide is engineered for once-monthly dosing. These are reference values for the native or representative form — educational only, not dosing advice.
