💡 Bottom Line
Mounjaro and Zepbound are the same drug (tirzepatide) by Eli Lilly. Mounjaro is approved for diabetes with broader insurance coverage. Zepbound is approved for weight loss with LillyDirect self-pay starting at $299/month. If you have diabetes, Mounjaro may be your cheapest path to tirzepatide.
If you've been comparing tirzepatide prices, you've probably noticed two brand names: Mounjaro (for diabetes) and Zepbound (for weight loss). They're the same molecule, the same doses, the same injection — just different labels and different insurance treatment.
