What it is
A dual incretin agonist, studied in the lab.
Tirzepatide is a synthetic single-chain peptide studied in vitro as a dual agonist of the glucose-dependent insulinotropic polypeptide (GIP) receptor and the glucagon-like peptide-1 (GLP-1) receptor. Research characterization focuses on receptor binding and downstream cAMP signaling at both incretin receptors. Supplied as a lyophilized powder for laboratory research — not for human or veterinary use, and not a drug or dietary supplement.

Questions
What researchers ask.
Is Tirzepatide third-party tested?
Yes. Every batch ships with a lot-specific Certificate of Analysis — purity by RP-HPLC and identity by mass spectrometry from an independent ISO 17025 laboratory, verifiable by batch ID.
What is Tirzepatide?
Tirzepatide is a synthetic dual incretin-receptor agonist peptide studied in vitro at the GIP and GLP-1 receptors. It is supplied strictly for laboratory research.
What receptors does Tirzepatide target?
In receptor-binding and cAMP-signaling assays it acts as an agonist at two incretin-family receptors: the GIP receptor and the GLP-1 receptor.
Is Tirzepatide for human or veterinary use?
No. It is for laboratory and research use only — not for human or veterinary use, and not a drug or dietary supplement. You must be 21 or older to purchase.
