Retatrutide (LY3437943) is a single peptide engineered to activate three receptors at once — GLP-1, GIP and glucagon. Research describes this triple-agonism combining appetite and glucose effects (GLP-1/GIP) with increased energy expenditure (glucagon), and it is being evaluated in clinical trials for metabolic endpoints.
N Engl J Med · 2023
