Tirzepatide (CAS 2023788-19-2, molecular formula C225H348N48O68), commonly shortened to Tirz and known as a prescription medicine under the brand names Mounjaro and Zepbound, is a synthetic dual GIP and GLP-1 receptor agonist peptide studied for its interaction with incretin receptor signalling pathways. PhaseOne has tirzepatide peptide for sale online to researchers across Australia as a high-purity lyophilised powder, independently HPLC verified at ≥99% purity per batch.
As a dual-incretin research peptide, Tirz is studied alongside related metabolic peptides such as Retatrutide within Australian peptide research, manufactured to research-grade standards and independently third-party tested for identity and consistency, with every order shipped Australia-wide.

Tirzepatide is a synthetic 39-amino-acid peptide and dual GIP/GLP-1 receptor agonist, studied within Australian peptide research for its interaction with incretin receptor signalling pathways.
Tirz is the common shorthand for Tirzepatide, and tirzepatide peptide is the same thing again. It is frequently mistyped as tirzeptide. All refer to the same dual GIP/GLP-1 receptor agonist. PhaseOne supplies Tirz peptide in 10mg vials for laboratory research use only.
Yes. PhaseOne has Tirz peptide for sale online in 10mg vials, shipped Australia-wide. Search results for tirzepatide online mix three separate categories: telehealth and pharmacy services dispensing prescription Mounjaro, compounding pharmacies preparing their own, and research suppliers selling lyophilised powder. PhaseOne is the last of those, with a batch Certificate of Analysis on every vial.
Mounjaro is a brand name under which tirzepatide is supplied as a prescription medicine. The active peptide is the same, but the branded medicine and PhaseOne's research-grade lyophilised powder are different products supplied through entirely different channels. PhaseOne supplies tirzepatide for laboratory research only.
Both contain the same active peptide, tirzepatide. They are separate brand names used for different approved indications: Mounjaro for type 2 diabetes, Zepbound for weight management in the markets where it is registered. Neither is what PhaseOne supplies.
Semaglutide is a single-receptor GLP-1 agonist, sold under brand names including Ozempic and Wegovy. Tirzepatide binds two receptors, GIP and GLP-1, making it a dual agonist. The receptor count is the core structural difference between the two.
Compounded tirzepatide refers to preparations made up by compounding pharmacies rather than supplied as a registered branded medicine. That is a pharmacy activity and a separate category again from research-grade material. PhaseOne supplies tirzepatide as a lyophilised research powder, not as a compounded or dispensed preparation.
PhaseOne ships tirzepatide Australia-wide for research use, dispatched locally with tracking, in 10mg vials. Every vial carries a batch-specific Certificate of Analysis verifying ≥99% HPLC purity.
PhaseOne prices tirzepatide at A$109.99 for a 10mg vial, with the batch Certificate of Analysis included at no extra cost. Current pricing is shown on this page.
Chemist Warehouse and other Australian pharmacies dispense tirzepatide as the prescription medicine Mounjaro, on prescription only. They do not stock research-grade tirzepatide in vial form, which is a different product category and what PhaseOne supplies.
Tirzepatide is a dual GIP/GLP-1 receptor agonist, whereas Retatrutide is a triple GIP/GLP-1/glucagon receptor agonist; the two have distinct receptor profiles studied within metabolic peptide research. (!) Compare them in our Retatrutide vs Tirzepatide guide, or view our Retatrutide.
Unreconstituted tirzepatide should be stored refrigerated and protected from light, and is commonly reconstituted with bacteriostatic water prior to research preparation. (!) Read our reconstitution guide.
Each batch of tirzepatide is independently verified by third-party HPLC analysis, with a Certificate of Analysis available for every order shipped across Australia.
All products supplied by PhaseOne are intended strictly for laboratory research purposes only. Products are not intended for human consumption, therapeutic use, cosmetic use, veterinary use, or diagnostic applications.
