Tirzepatide Injection Pen is a synthetic peptide drug that mimics the effects of two key incretin hormones: GLP‑1 (glucagon-like peptide-1) and GIP (glucose-dependent insulinotropic polypeptide). These hormones are released by the gut in response to food intake and play major roles in blood sugar regulation, appetite suppression, and fat metabolism.

What sets tirzepatide apart is its dual-agonist mechanism, which means it simultaneously stimulates both the GLP-1 and GIP receptors. This combined action enhances insulin secretion, slows gastric emptying, and significantly reduces hunger — making it incredibly effective for weight loss and metabolic control.
