Tirzepatide — The Dual Agonist Research Compound

Tirzepatide is a 39-amino-acid synthetic peptide that simultaneously agonizes the GIP receptor (GIPR) and GLP-1 receptor (GLP-1R) — earning it the “twincretin” designation in research literature. While semaglutide targets GLP-1R alone, tirzepatide’s dual mechanism engages adipose tissue biology, incretin signalling, and pancreatic beta-cell pathways through both receptor systems. Clinical research in the SURPASS and SURMOUNT programmes produced a large dataset characterizing its metabolic effects.

FAQs

Can I buy tirzepatide in Canada for research?

Yes. TrueCanPeptides supplies tirzepatide as a research compound for qualified laboratory use, shipped domestically across Canada. Not for human administration.

Is tirzepatide the same as Mounjaro?

Mounjaro is an approved pharmaceutical formulation of tirzepatide, regulated by Health Canada and the FDA. TrueCanPeptides supplies tirzepatide as a raw research peptide for in vitro laboratory use only — not as a pharmaceutical formulation and not for human administration.

What purity is your tirzepatide?
