Description

Dual GIP and GLP-1 receptor agonist on a GIP backbone. Studied in incretin-signalling, glucose-homeostasis, and adipose-metabolism research.

  • 39 amino acid dual GIP/GLP-1 receptor agonist
  • Aib at positions 2 and 13 resists DPP-4 cleavage
  • C20 diacid linker confers albumin binding and extended half-life
  • Studied in insulin-sensitivity and lipid-metabolism research
  • Research Grade purity >=98%

Tirzepatide is a synthetic 39 amino acid peptide identified by CAS number 2023788-19-2 that acts as an agonist at both the glucose-dependent insulinotropic polypeptide (GIP) receptor and the glucagon-like peptide-1 (GLP-1) receptor. It is built on a GIP backbone rather than a GLP-1 one, which is the structural feature behind its dual-agonist profile and the reason it is studied alongside, rather than as a substitute for, single-agonist GLP-1 analogues. Alpha-aminoisobutyric acid (Aib) at positions 2 and 13 resists dipeptidyl peptidase-4 cleavage, and an eicosanedioic (C20) fatty diacid attached to the Lys20 side chain through a gamma-glutamyl and two AEEA spacers binds serum albumin, extending circulating half-life in the models studied. Research has investigated the combined incretin signalling observed in preclinical models: glucose-dependent insulin secretion, insulin sensitivity in adipose and skeletal muscle tissue, lipid handling, and central appetite regulation. Tirzepatide is supplied as a lyophilised white powder with a molecular weight of 4813.45 Da and molecular formula C225H348N48O68. Supplied strictly for in-vitro laboratory research. Not for human or veterinary consumption.

Frequently Asked Questions

Is Tirzepatide legal to buy in Australia?

Tirzepatide is supplied strictly as a research chemical for in-vitro laboratory use. It is not approved for human therapeutic use in Australia and is not for human or animal consumption. Researchers are responsible for compliance with Therapeutic Goods Administration (TGA) regulations and their institution's protocols.

What purity is Tirzepatide?

We specify ≥98% purity — the High-Tier Research Grade (commercial RUO) standard. Every batch is analysed in-house by HPLC and mass spectrometry and ships with a Certificate of Analysis; select batches also undergo independent, third-party purity verification.

Does Tirzepatide ship with a Certificate of Analysis (COA)?

Yes — every batch ships with a batch-specific COA documenting HPLC purity and mass-spectrometry identity. 1 Tirzepatide batch certificate is published in full at australianpeptidelabs.com.au/certificates/tirzepatide, so the analysis can be read before ordering and the batch number printed on the vial matched against it.

Where can I buy Tirzepatide in Australia?

Tirzepatide can be ordered here from Australian Peptide Labs for in-vitro research use, dispatched same day from within Australia with a COA included.

Do you provide dosing or administration guidance for Tirzepatide?

No. As these compounds are supplied for laboratory research only, we do not provide dosing or administration protocols. Our research library covers reconstitution and concentration calculations for in-vitro work.
