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 Pen is a pre-filled research pen containing tirzepatide, a dual GIP and GLP-1 receptor agonist peptide, supplied by MyPeptides for laboratory research use only.
The Tirzepatide Pen is a pre-filled research pen holding 40 mg of tirzepatide, the 39-amino-acid peptide that activates both the GIP and GLP-1 receptors. The ready-assembled format keeps the quantity per pen fixed and labelled, which removes the reconstitution step from the bench workflow.
Tirzepatide is one of the most-studied compounds in laboratory incretin research, used to compare dual-receptor signalling with selective GLP-1 agonists such as semaglutide and with the triple agonist retatrutide. All three are listed in our GLP-1 & incretin range.
Pens are held in stock in the UK and dispatched the same working day when ordered before 12:00, with tracked delivery that is free on orders over £50. Store refrigerated at 2–8 °C, protected from light. Supplied strictly for laboratory research — not for human or veterinary use.

Vials in perfect condition
Ordered late Monday, arrived Wednesday morning in the UK. Packaging was cold-protected and every vial sealed correctly. CoA matched the batch number on the label.

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.

Great documentation
Support answered a batch question within a few hours over email. Rare to get that level of response from a research supplier. Product itself is exactly to spec.
