Tirzepatide 40mg — High-Strength Research Peptide
Tirzepatide 40mg is the highest-strength single-vial presentation in our Tirzepatide range, formulated for laboratory researchers who require a larger quantity of peptide per vial. Each vial contains 40mg of Tirzepatide as a lyophilised (freeze-dried) powder, sealed under inert conditions and independently assayed to ≥99% purity.
Tirzepatide is a synthetic dual-agonist peptide that acts on both the glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptors, making it a widely used reference compound in metabolic and receptor-signalling research models.

Why choose a 40mg vial?
A single Tirzepatide 40mg vial consolidates what would otherwise require multiple lower-strength vials, reducing the number of reconstitutions and the per-milligram cost across a research programme. Researchers mapping dose-response often pair it with our Tirzepatide 20mg and Tirzepatide 10mg presentations.
Purity & third-party testing
Every batch of Tirzepatide 40mg is independently analysed by Janoshik Analytical, a leading third-party testing laboratory. A Certificate of Analysis (COA) confirming identity and purity is available on request, so you can rely on the consistency of every vial.
Storage & handling
Store the lyophilised powder sealed at -20°C, protected from light. Once reconstituted with bacteriostatic water, keep refrigerated and use within the window appropriate to your protocol. Handle in line with good laboratory practice.
