Tirzepatide is a dual GIP (glucose-dependent insulinotropic polypeptide) and GLP-1 (glucagon-like peptide-1) receptor agonist. In preclinical research, this dual mechanism has been investigated for its effects on insulin secretion, glucose homeostasis, appetite signaling pathways, and adipose tissue metabolism.

Tirzepatide is studied in models of glucose-dependent insulin release, beta-cell function, gastric emptying, and weight-regulation signaling. Its half-life of ~5 days in research models allows investigation of extended-duration receptor engagement.
