Our take

The bottom line

Two different molecules for weight management. Here’s how to think about it.

Choose based on your goal

  • Choose Zepbound if you want the highest average weight loss outcomes currently available. Its dual GIP/GLP-1 mechanism consistently outperforms semaglutide-only options.
  • Choose Wegovy if you prefer a more established weight loss track record, have used GLP-1 treatment before, or need broader insurance compatibility for weight management.

Common questions

What you
need to know

In trials, Zepbound (tirzepatide 15 mg) produced an average weight loss of about 21%, compared to about 15% for Wegovy (semaglutide 2.4 mg). Zepbound’s dual GIP/GLP-1 action consistently delivers stronger average results, though both are highly effective.

Yes, with provider guidance. Because the molecules differ, your provider will typically restart you at Zepbound’s lowest dose (2.5 mg weekly) and titrate up over several weeks to manage tolerability and side effects.

On average, Zepbound produces more weight loss in head-to-head data, but individual response varies. Tolerability, insurance coverage, and personal history with GLP-1 medications all factor into which is the better choice for a given patient.

Yes. Both Zepbound and Wegovy require a prescription from a licensed healthcare provider. A consultation is required to assess whether treatment is appropriate for you.
