About this compound
Tirzepatide
Dual GIP / GLP-1 analogue
Half-life
≈ 5 days
First disclosed
2018
Tirzepatide is a 39-amino-acid synthetic peptide that activates both the GIP and GLP-1 receptors. Originally disclosed by Eli Lilly in 2018, it is among the most-studied incretin compounds in laboratory metabolic-pathway research, with peer-reviewed work spanning receptor binding and incretin-axis signalling models.
Co-activation of the GIP and GLP-1 receptors is studied in vitro for its combined effect on incretin-receptor signalling pathways.

Tirzepatide is a dual GIP and GLP-1 receptor agonist peptide, supplied by MyPeptides for laboratory research use only.
Tirzepatide is a 39-amino-acid synthetic peptide that activates both the GIP and GLP-1 receptors (C₂₂₅H₃₄₈N₄₈O₆₈, CAS 2023788-19-2). First disclosed in 2018, it is among the most-studied compounds in laboratory incretin-pathway research.
It is supplied here as a 5 mg lyophilised vial and as a 40 mg pre-filled research pen, so protocols can use whichever format suits the workflow.
Compare it with semaglutide (GLP-1 only), mazdutide (GLP-1 + glucagon) and retatrutide (GIP + GLP-1 + glucagon) in our GLP-1 & incretin range. Store at −20 °C, protected from light. Laboratory research use only.

Vials in perfect condition
Really impressed with the packaging quality. Everything double-boxed, insulated and clearly labelled. Same day dispatch worked as promised.

Arrived quickly, well protected
Documentation is what sold me. Independent CoA per batch, clean HPLC traces. Reconstitution behaved exactly as expected. Solid supplier for research use.

Consistent batch to batch
Shipping to mainland EU took 3 working days, tracked the whole way. Vials arrived intact, labels crisp, seals unbroken. Reordering next month.

Fast UK shipping
The little details matter - proper cold-chain, tamper-evident seals, and a CoA that actually reads like a lab report and not a marketing sheet.

Reference-grade quality
Ordered a bundle to save on shipping - all vials arrived in one insulated pack, labels identical batch, CoA covers the lot. Great value.
