Tirzepatide is a synthetic investigational peptide designed to activate:

• GLP-1 (Glucagon-Like Peptide-1) receptors

• GIP (Glucose-Dependent Insulinotropic Polypeptide) receptors

These incretin hormones are naturally released after meals and play central roles in:

• Hunger and satiety signaling

• Glucose metabolism

• Insulin sensitivity

• Energy balance

By activating both pathways simultaneously, Tirzepatide allows researchers to study coordinated metabolic regulation, rather than isolated mechanisms.
