Disclaimer & Storage Guide

What is Tirzepatide?

Tirzepatide is a dual glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptor agonist — the first-in-class twincretin. Acts simultaneously on GIPR and GLP-1R to produce synergistic effects on insulin secretion, glucagon suppression, gastric emptying, and appetite suppression. Phase 3 (SURMOUNT-1): 20.9% mean weight loss at 72 weeks (15mg). The 120mg vial format provides high total peptide loading per kit for extended research protocols. Research use only.

Research Applications

Dual GIP/GLP-1 Receptor Agonism

Simultaneous GIPR + GLP-1R activation — synergistic vs individual receptor pharmacology

Incretin Axis Research

GIP/GLP-1 co-signalling, cAMP pathway, beta-cell insulin secretion and glucagon suppression

Metabolic & Weight Research

SURMOUNT-1 reference compound — 20.9% mean weight loss at 72 weeks

Glucose Homeostasis

Postprandial glucose excursion, hepatic glucose output, peripheral insulin sensitivity

Twincretin vs Monoagonist

Tirzepatide vs GLP-1R-only agonists — additive/synergistic metabolic outcomes comparison

Frequently Asked Questions

How do I reconstitute Tirzepatide?
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 Tirzepatide 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 Tirzepatide and how is it verified?
QSC Tirzepatide 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.
