What to Know About Retatrutide

Explore the scientific updates and data regarding Lilly’s investigational, once-weekly injectable triple hormone receptor agonist under clinical development for obesity management.

The Triple Agonist Mechanism

GIP Receptor

Targets the Glucose-dependent insulinotropic polypeptide to aid energy balance regulation.

GLP-1 Receptor

Activates Glucagon-like peptide-1 pathways helping appetite suppression and metabolic controls.

Glucagon Receptor

Simultaneously engages the glucagon receptor to enhance metabolic expenditure.

Strictly Investigational Phase

Retatrutide is **not yet approved** by the FDA or any global regulatory agencies for public sale. It is currently being carefully evaluated in Phase 3 trials to fully verify safety, dosage, and efficacy parameters. No unauthorized product should be acquired outside Lilly-sponsored clinical trials.
