About Retatrutide (LY3437943)
Retatrutide is Eli Lilly’s investigational triple receptor agonist, simultaneously activating GLP-1R (glucagon-like peptide-1 receptor), GIPR (glucose-dependent insulinotropic polypeptide receptor), and GCGR (glucagon receptor). Phase 2 data (Jastreboff et al., NEJM 2023) reported 24.2% mean body weight reduction at 48 weeks at the 12mg dose — the largest reported for any injectable drug in Phase 2 at that time. Phase 3 TRIUMPH trials are ongoing.
Adding glucagon receptor activation to the dual GLP-1R+GIPR mechanism of tirzepatide introduces thermogenic and lipolytic pathways that increase total energy expenditure — the proposed mechanism behind retatrutide’s greater weight reduction vs dual agonists. For researchers comparing triple vs dual receptor agonism, retatrutide and tirzepatide parallel experimental arms are the standard approach to isolating the GCGR contribution.
Reconstitution and storage
Reconstitute QSC retatrutide in bacteriostatic water to a 1mg/mL stock. Store lyophilized powder at -20°C (stable 12–24 months sealed). Reconstituted solution: refrigerate at 4°C and use within 3–4 weeks, or aliquot and freeze at -20°C for up to 6 months.
