What is Retatrutide?

Retatrutide (Triple GLP-1R/GIPR/GCGR agonist (LY3437943)) is a 39-amino acid triple-receptor peptide. Triple receptor co-agonist simultaneously activating GLP-1R, GIPR, and GCGR. GCGR activation adds thermogenesis, fatty acid oxidation, and hepatic glucose production modulation beyond dual GIP+GLP-1 agonism. Phase 2 (NEJM 2023): 24.2% mean weight reduction at 48 weeks (12mg dose).

Research Applications

Frequently Asked Questions

How do I reconstitute Retatrutide?
Add 1–2mL of bacteriostatic water slowly down the side of the vial. Do not shake — gently swirl until the lyophilized powder fully dissolves. The resulting solution should be clear and colourless. Use a 1mL insulin syringe for accurate sub-milligram dosing.
How should Retatrutide be stored?
Store lyophilized vials at −20°C (freezer). Once reconstituted, store at 2–8°C (refrigerator) and use within 21–28 days. Keep away from light and repeated freeze-thaw cycles. Do not use if the solution is cloudy or contains visible particles.
What purity is QSC Retatrutide and how is it verified?
QSC Retatrutide is tested to ≥99% purity by analytical HPLC on every batch. Molecular identity is confirmed by mass spectrometry. A Certificate of Analysis (COA) is published on the product page and independently verifiable at verify.janoshik.com using the batch reference number.
