What is Retatrutide?
Retatrutide (LY3437943) is a single synthetic peptide engineered to activate three receptors: GLP-1, GIP and glucagon. It carries a fatty-acid modification that supports once-weekly pharmacokinetics in research settings.
Mechanism of Action
GLP-1 and GIP agonism support glucose-dependent insulin secretion, delayed gastric emptying and reduced appetite signalling. Added glucagon-receptor activity increases hepatic fat oxidation and energy expenditure—a distinguishing feature compared with dual incretin agonists.
Research Applications
Retatrutide is studied in obesity, type 2 diabetes and hepatic steatosis research, where the tri-agonist approach is compared against single and dual incretin agonists for effects on body composition and liver fat.
Storage & Handling
Supplied as a lyophilized (freeze-dried) powder for maximum stability. Store unopened vials at -20°C, protected from light. Once reconstituted with bacteriostatic water, keep refrigerated at 2–8°C and use within the timeframe appropriate to your study protocol.
