What is Tirzepatide?

Tirzepatide (Dual GIP+GLP-1 receptor agonist) is a 39-amino acid dual-modified synthetic peptide. First approved dual GIP and GLP-1 receptor co-agonist — one molecule activating both incretin receptors simultaneously. GIPR co-agonism adds: adipose lipolysis, thermogenesis, and hypothalamic GLP-1R sensitisation. SURMOUNT-5 (2025): 20.2% vs 13.7% mean weight reduction vs semaglutide 2.4mg at 72 weeks. SURPASS-2: superior HbA1c vs semaglutide 1mg.

Frequently Asked Questions

How do I reconstitute Tirzepatide?
Add 1–2mL of bacteriostatic water slowly to the lyophilized vial. Gently swirl — do not shake or vortex. The peptide dissolves to a clear, colourless solution. Use a 1mL insulin syringe for precise sub-milligram dosing of this potent dual agonist.
How should Tirzepatide be stored?
Store lyophilized at −20°C. Reconstituted solution: 2–8°C refrigerator, use within 21–28 days. Avoid repeated freeze-thaw cycles and direct light exposure. Reconstituted Tirzepatide is stable for approximately 3–4 weeks refrigerated.
What purity is QSC Tirzepatide and how is it verified?
QSC Tirzepatide is ≥99% pure by HPLC peak area analysis and MS-confirmed for molecular weight on every production batch. COA is published on the product page and independently verifiable via verify.janoshik.com.
