GLP3-R is a triple receptor agonist research peptide in the retatrutide class, engineered to activate GLP-1, GIP, and glucagon receptors simultaneously. It is studied in metabolic research models examining energy balance, incretin signaling, and body composition.
GLP3-R is a synthetic triple agonist research peptide modeled on the retatrutide class of investigational compounds. By engaging three distinct receptors — GLP-1, GIP, and glucagon — in a single molecule, it gives laboratories a tool for examining how combined incretin and glucagon signaling influences energy expenditure, appetite-related pathways, and glucose regulation in preclinical models.
