Retatrutide is a synthetic research peptide studied for its interaction with three important metabolic receptors: GLP-1, GIP and glucagon. Because it targets all three pathways, it is commonly described as a triple-receptor agonist. Research focuses on how these pathways influence appetite regulation, glucose and lipid metabolism, energy balance and overall metabolic signalling. Its unique three-pathway activity has made Retatrutide an important compound in modern metabolic research. For research purposes only.
