How It Works

Tirzepatide activates both glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptors. These actions help regulate appetite, delay stomach emptying, and reduce food intake, supporting clinically significant weight loss when combined with healthy lifestyle changes.
