Survodutide vs Retatrutide
A dual glucagon and GLP-1 receptor agonist — the co-agonist that skips GIP and aims at the liver. 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 Survodutide and Retatrutide?
- Survodutide is an engineered analog based on Glucagon-like peptide-1; Retatrutide is an engineered analog based on Glucagon-like peptide-1. Survodutide signals at Glucagon receptor (GCGR) + GLP-1 receptor; Retatrutide signals at GIP + GLP-1 + glucagon receptors.
- How do the half-lives of BI 456906 and Retatrutide compare?
- The reported circulating half-life of Survodutide is engineered for once-weekly dosing; Retatrutide is ~6 days. These are reference values for the native or representative form — educational only, not dosing advice.
