Tirzepatide — Research Peptide (Lyophilised, HPLC ≥99%)

Lyophilised Tirzepatide is stable for up to 24 months at -20°C unopened, or for short-term use at 2–8°C. After reconstitution with bacteriostatic water, the solution should be stored at 2–8°C and used within 28 days under sterile conditions. Avoid repeated freeze–thaw cycles. Keep vials away from direct light and let them reach room temperature before opening to prevent moisture ingress.

Bacteriostatic water (0.9% benzyl alcohol in sterile water) is the standard diluent for laboratory reconstitution of Tirzepatide because the preservative inhibits microbial growth in solutions stored beyond 24 hours. Inject the diluent slowly down the wall of the vial, swirl gently, and do not shake. The volume used depends on the target working concentration for the research protocol. Bacteriostatic water is sold separately on our store.

Tirzepatide is supplied at a typical HPLC purity of ≥98%. The COA published on the product page confirms identity (sequence, molecular formula and weight), HPLC purity, MS confirmation where applicable, lyophilised appearance and the batch / lot reference. Researchers requiring batch-specific external verification can request the lot number and commission independent third-party HPLC.

Orders placed before 3pm Mon–Fri ship the same working day via tracked next-day courier (Royal Mail or DPD). Vials are packed in temperature-buffered, discreet outer packaging and arrive in 1–2 working days for UK addresses. Tracking is emailed at dispatch.

Yes. Every batch is verified by HPLC for purity and identity, with mass spectrometry confirmation where applicable. An in-house Certificate of Analysis is published on the product page, and we routinely commission independent third-party testing on batches at random to confirm internal results. Researchers requiring batch-specific external verification can request the lot reference and arrange independent testing.

Combination protocols are at the discretion of the researcher and depend on the experimental design. Tirzepatide is commonly studied alongside other GLP-1 / GIP-class compounds such as Retatrutide, Semaglutide and Cagrilintide in published metabolic research. Any combination work should be planned with appropriate analytical controls, and stored in line with the most restrictive stability profile of the compounds involved.
