02Mechanism of Action

Tirzepatide is a synthetic 39-amino-acid peptide engineered as a dual agonist of the glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptors. In research models it is studied for the combined activation of both incretin pathways and downstream effects on insulin secretion, glucose homeostasis, and energy metabolism.

Its dual-receptor mechanism is the principal distinction from single GLP-1 agonists, making it a key reference compound in comparative incretin and metabolic-pathway research.

05Frequently Asked Questions

What is Tirzepatide?

Tirzepatide is a synthetic dual GIP/GLP-1 receptor agonist studied for incretin signaling and metabolic regulation in research models. It is sold for research use only and is not for human consumption.

How is Tirzepatide different from Semaglutide?

Tirzepatide activates both the GIP and GLP-1 receptors (dual agonist), while Semaglutide targets only the GLP-1 receptor. The dual mechanism is the focus of comparative metabolic research.

What is the molecular weight of Tirzepatide?

Tirzepatide has a molecular weight of approximately 4,813.45 g/mol and CAS number 2023788-19-2.
