Retatrutide is an experimental peptide being studied as a triple-receptor agonist, meaning it activates three hormone receptors — GLP-1, GIP, and glucagon. Researchers are investigating how this combined activity may affect metabolism, appetite control, energy balance, and blood sugar regulation. Early and ongoing studies have looked at its effects on body weight, insulin response, and liver fat, and scientists continue to compare it with other GLP-1–based research compounds.
