Tirzepatide

Glucose-Dependent Insulinotropic Polypeptide (GIP) / GLP-1 Dual Agonist

Tirzepatide is a 39-amino-acid synthetic peptide engineered with dual agonism at both glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptors. Investigated in extensive clinical trials and preclinical pharmacological assays for glucose homeostasis, lipolytic modulation, and pancreatic beta-cell insulin secretion.
