Tirzepatide

What it is: A dual GIP and GLP-1 receptor agonist — the same molecule used in Mounjaro and Zepbound. It mimics two natural gut hormones that regulate hunger and blood sugar.

What it does: You can expect significant weight loss — often 15-22% of body weight over 6-12 months — alongside reduced appetite, fewer food cravings, better blood sugar control, and improvements in cholesterol and blood pressure markers.

How it's used: Once-weekly subcutaneous injection. Titrate up slowly from a low starting dose (2.5 mg) to allow the body to adjust.
