Mounjaro vs Ozempic: Which GLP-1 is More Effective?
The newest GLP-1 showdown: Mounjaro (tirzepatide) delivers better weight loss results, but is it worth the higher cost and side effects?
Quick Summary:
Mounjaro (tirzepatide) is MORE effective for weight loss (15-22% vs 10-15% with Ozempic), but also MORE expensive ($1,000+ vs $935/month) and may cause MORE side effects. Both work similarly but Mounjaro is a dual-action drug (GLP-1 + GIP).
