Retatrutide vs Maridebart cafraglutide
An investigational GIP/GLP-1/glucagon triple receptor agonist. GLP-1 agonism paired with GIP receptor antagonism — the opposite GIP direction to tirzepatide. 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 Maridebart cafraglutide?
- Retatrutide is an engineered analog based on Glucagon-like peptide-1; Maridebart cafraglutide is an engineered analog based on Glucagon-like peptide-1. Retatrutide signals at GIP + GLP-1 + glucagon receptors; Maridebart cafraglutide signals at GLP-1 receptor (agonist) + GIP receptor (antagonist).
- How do the half-lives of Retatrutide and MariTide compare?
- The reported circulating half-life of Retatrutide is ~6 days; Maridebart cafraglutide is ~21 days (monthly dosing). These are reference values for the native or representative form — educational only, not dosing advice.
