How does semaglutide compare to tirzepatide for weight loss?
Tirzepatide (Mounjaro/Zepbound) generally produces greater weight loss than semaglutide (Ozempic/Wegovy) in head-to-head comparisons. The SURPASS trials showed tirzepatide achieving 15-22% body weight reduction, while STEP trials for semaglutide showed 15-17% average weight loss. Tirzepatide's dual mechanism - activating both GLP-1 and GIP receptors - provides enhanced appetite suppression and metabolic effects. However, semaglutide has longer real-world safety data and may be better tolerated by some patients. Both require weekly subcutaneous injections and have similar gastrointestinal side effect profiles.
