Retatrutide
Retatrutide (LY3437943) — Triple GLP-1 / GIP / glucagon receptor agonist
Research use only — intended for laboratory research. Not for human or veterinary use.
Retatrutide (LY3437943) is a first-in-class triple incretin receptor agonist designed by Eli Lilly. The molecule simultaneously engages the GLP-1, GIP, and glucagon receptors — adding glucagon-receptor activation to the dual GLP-1/GIP profile of tirzepatide. A C20 fatty diacid is conjugated to enable non-covalent albumin binding and extend the half-life to roughly 6 days. In SURMOUNT and Phase 2 obesity trials, retatrutide produced the largest body-weight reductions reported to date for any peptide agent, making it one of the most closely watched molecules in current metabolic research.
