    Tirzepatide is a first-in-class dual GIP and GLP-1 receptor agonist with a once-weekly research profile. Published peer-reviewed research has investigated its alleged role in synergistic incretin signalling, superior glycaemic control versus single-agonist comparators and substantial weight reduction across the SURPASS and SURMOUNT trial programs. These are research findings only — not medical claims and not a recommendation for human use. Independently lab-tested at ≥99% purity by HPLC, with a third-party Certificate of Analysis available for every batch. Reconstitute by drawing 3ml of the included BAC water and slowly injecting it down the inside wall of the 5mg vial — never directly onto the lyophilised powder. Gently swirl until fully dissolved; do not shake. Once reconstituted, store between 2–8°C and use within 30 days. Store unopened lyophilised vials at 2–8°C, away from direct light. Once reconstituted, refrigerate at 2–8°C and use within 28–30 days. This product is sold strictly for research purposes only. Not for human consumption, and not intended to diagnose, treat, cure or prevent any disease or condition.
