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