Buy Tirzepatide peptide as lyophilised powder in sealed vials of 5 mg, 10 mg, 15 mg or 30 mg. Tirzepatide is a synthetic peptide of 39 amino acids that binds two receptors, GLP-1 and GIP. In laboratories it is a common reference compound for dual agonist assays. The product on this page is a research chemical, not a medicine.

Buy Tirzepatide: vial sizes and form

Tirzepatide is supplied in four vial sizes. The 5 mg vial covers single receptor assays, the 10 mg and 15 mg vials are intended for series, and the 30 mg vial for laboratories that run several cell lines from one lot. Every vial contains lyophilised powder under a sealed cap, with the amount and the lot number printed on the label. For documented batches a certificate of analysis is available on request with that lot number, reporting identity by mass spectrometry and purity by HPLC; these products are listed under peptides with certificate of analysis. For comparison studies the single agonist Semaglutide and the triple agonist Retatrutide are listed with Tirzepatide under GLP-1 and metabolic research peptides.

What Tirzepatide is: a GIP analogue that also binds GLP-1

Tirzepatide is built on the sequence of human GIP, modified so that it also activates the GLP-1 receptor. Like Semaglutide it carries a fatty diacid side chain that binds to albumin and stabilises the molecule. In assays the compound is used to measure how one peptide addresses two receptors, and how this differs from a single agonist. For analytics the defined mass of about 4,814 Da is confirmed by mass spectrometry.

Questions about Tirzepatide

Is the Tirzepatide in this shop a medicine?

No. As of October 2026, medicines with this active substance are authorised in the EU, but the product on this page is not one of them: it is a research chemical for laboratory use without an authorisation of its own. We give no information on use in humans.

How does Tirzepatide differ from Semaglutide and Retatrutide?

By the number of receptors: Semaglutide binds GLP-1, Tirzepatide binds GLP-1 and GIP, Retatrutide binds GLP-1, GIP and glucagon. This is a structural difference used in receptor research, not a statement about effects.
