Retatrutide is Eli Lilly's investigational once-weekly triple agonist (GIP, GLP-1 and glucagon receptors). Five Phase 3 trials have reported positive results, and Lilly plans to submit it to the FDA in Q1 2027. It is not FDA-approved, has no brand name or price, and cannot be prescribed outside clinical trials or Lilly's physician-requested expanded access program. Products sold online as "research" or compounded retatrutide are not legitimate retatrutide.
Next milestone: TRIUMPH-5 head-to-head vs tirzepatide results (Expected ~Dec 2026)
