      Frequently Asked Questions

      Is tirzepatide better than semaglutide?

      In the SURMOUNT-5 head-to-head trial, tirzepatide produced 20% weight loss vs. 14% for semaglutide over 72 weeks. Tirzepatide is more effective for weight loss. However, semaglutide has more long-term cardiovascular outcome data.

      What is the difference between Mounjaro and Zepbound?

      Both contain tirzepatide. Mounjaro is FDA-approved for type 2 diabetes. Zepbound is FDA-approved for chronic weight management. The drug is identical; the indication differs.

      How does tirzepatide's dual mechanism work?

      Tirzepatide activates both GIP (glucose-dependent insulinotropic polypeptide) and GLP-1 receptors. GLP-1 reduces appetite and slows gastric emptying. GIP enhances insulin secretion and may reduce GLP-1 side effects. The combination produces greater weight loss than GLP-1 agonism alone.
