What is Retatrutide?

Retatrutide (LY3437943) is a 39-amino acid 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 at the 12mg dose. The 120mg vial format delivers 1,200mg total per 10-vial kit for extended research protocols. Research use only.

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 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.
What purity is QSC Retatrutide and how is it verified?
QSC Retatrutide is tested to ≥99% purity by 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.
