CAS Number: 2381089-83-2 Molecular formula:C221H342N46O68 Molar mass: 4731 g/mol Medical use: Retatrutide is a GGG tri-agonist that targets GLP-1 and GIP receptors. Similar to standard GLP-1 agonists, it uniquely activates the glucagon receptor as well. This additional receptor interaction promotes glucagon production, leading to the breakdown of stored fat and glycogen, thereby increasing basal metabolism and resulting in more consistent fat reduction.
