GLP-1 · GIP dual agonist
Tirzepatide is the dual-agonist research peptide — it activates both the GLP-1 and GIP receptors, the same molecule marketed under the brand names Mounjaro and Zepbound as a prescription medicine. Canada Peptides carries research-grade tirzepatide, priced and shipped in CAD. Everything below is for research and educational use only.
Tirzepatide is a dual agonist — it engages both the GLP-1 and GIP receptors on a single peptide backbone. Adding the GIP arm to the GLP-1 axis is what sets it apart from single-agonist compounds. For the full mechanism, see the tirzepatide research overview.
Mounjaro and Zepbound are brand names under which tirzepatide is marketed as a prescription medicine. The material sold here is research-grade tirzepatide, supplied strictly for laboratory research use — it is not the branded pharmaceutical and is not for human use.
By receptor coverage: semaglutide is a single GLP-1 agonist, tirzepatide is a dual GLP-1/GIP agonist, and retatrutide is a triple GLP-1/GIP/glucagon agonist. The GLP-1 receptor agonists comparison breaks down how the three differ mechanistically.
Published tirzepatide protocols use once-weekly subcutaneous administration with gradual titration. Our dosing-math and reconstitution guides cover the handling math. This is research context only — not a dosing recommendation for human use.
Research-grade tirzepatide is available to order on this page, shipped within Canada in CAD for research use only. Reconstitution and handling guidance is linked above.

Tirzepatide dosage — research dosing notes
A literature overview of tirzepatide dosage: the 2.5 mg initiation step, four-week titration cadence, and 5/10/15 mg maintenance levels used in the trials, the ~5-day half-life behind once-weekly dosing, and reconstitution math for lyophilized vials. Research context only, not medical advice.
