    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 via independent ISO 17025 lab testing.

    Peptx stocks Retatrutide in 10mg, 15mg, 20mg, 30mg, 40mg, 50mg, and 60mg lyophilised vials, allowing laboratories to size purchases to their specific study design without wastage. Each vial ships as sterile lyophilised powder with manufacturer HPLC and Mass Spectrometry data.

    Why research labs buy Retatrutide from Peptx

    Factory-direct sourcing

    Peptx sources directly from manufacturers cross-referenced against independent ISO 17025 lab testing. No middlemen and no compounding-pharmacy markups; just the factory price plus a small fixed margin.

    Manufacturer HPLC data

    Manufacturer HPLC and Mass Spectrometry data sits behind Peptx material at typically 99%+ purity (HPLC). Documentation is not shipped with orders. Independent ISO 17025 lab retesting is encouraged; a 14-day refund window applies to any independently verified result below the product's stated guaranteed minimum purity.

    Retatrutide buying FAQ

    What is the difference between Retatrutide and Tirzepatide?
    Tirzepatide (LY3298176, branded Mounjaro and Zepbound) is a dual GLP-1 and GIP receptor agonist. Retatrutide (LY3437943) adds a third receptor target, the glucagon receptor, producing additional effects on hepatic glucose output and lipid metabolism. Published phase 2 data shows Retatrutide producing larger body-weight reduction effects than Tirzepatide head-to-head. See our full comparison at /retatrutide-vs-tirzepatide.
    What vial sizes do you stock?
    Peptx stocks Retatrutide in 10mg, 15mg, 20mg, 30mg, 40mg, 50mg and 60mg lyophilised vials. The 10mg and 15mg sizes are the most commonly ordered for general research studies.
    Is Retatrutide approved for use?
    No. Retatrutide is still in clinical development and has not received marketing approval from the FDA, MHRA, EMA or any other major regulator. All Peptx products are sold strictly for in-vitro laboratory research and are NOT for human or animal consumption.
    How is Retatrutide prepared in solution?
    Bacteriostatic water is the standard laboratory diluent. The volume added relative to the peptide mass on the vial label sets the resulting concentration in mg per mL.
    How long does Retatrutide last once reconstituted?
    Once reconstituted with bacteriostatic water, refrigerate at 2 to 8 Celsius and use within 4 to 6 weeks. Lyophilised vials are stable at -20 Celsius for extended storage.
