About Retatrutide as a research compound
Retatrutide (developmental code LY3437943) is a next-generation incretin peptide, designed as a single molecule that simultaneously activates the GLP-1, GIP, and glucagon receptors. Published phase 2 data from the TRIUMPH trial programme has shown substantially larger metabolic effects than any previously approved single-target or dual-target incretin peptide.
Because Retatrutide is still in late-stage clinical development and has not yet received marketing approval from the FDA, MHRA or EMA, it is not available through the licensed prescription supply chain. Research laboratories source the compound as a research-grade reference standard from specialist suppliers like Peptx, with provenance traceable to manufacturers vetted through independent lab testing.
Peptx stocks Retatrutide in 10mg, 15mg, 20mg, 30mg, 40mg, 50mg, 60mg and 100mg lyophilised vials, allowing laboratories to size purchases to their specific study design without wastage. Each vial ships as lyophilised powder.
