At A Glance Comparison
Wegovy and Zepbound both help with weight management, but they use different ingredients and offer different treatment options. Here’s Wegovy vs Zepbound, at a glance.
Wegovy vs Zepbound on Active Ingredients and How They Work
Wegovy contains semaglutide, a GLP-1 receptor agonist. It mimics the GLP-1 hormone your body naturally produces to help you:
- Feel less hungry throughout the day
- Stay full longer after eating
- Manage your blood sugar levels
Zepbound contains tirzepatide, which activates two hormone receptors: GLP-1 and GIP. This dual action helps your body:
- Regulate appetite and reduce hunger
- Improve blood sugar regulation
- Support greater feelings of fullness
What does this mean for your choice?
Wegovy vs Zepbound on Weight Loss Effectiveness
Both of these medications help people lose weight when they combine treatment with a reduced-calorie diet and regular physical activity. However, clinical trials show that Zepbound delivers greater average weight loss than standard-dose Wegovy.
In the 72-week SURMOUNT-5 clinical trial, researchers compared both medications in adults with obesity who did not have diabetes.
| Medication | Average Weight Loss |
|---|---|
Zepbound (tirzepatide) | 20.2% of starting body weight |
Wegovy (semaglutide) | 13.7% of starting body weight |
For example, if you weigh 200 pounds when you start treatment, these averages translate to approximately 40 pounds with Zepbound and 27 pounds with Wegovy.
Which Helps You Lose More Weight?
Zepbound produced greater average weight loss than standard-dose Wegovy injections in the SURMOUNT-5 trial.
However, your results will depend on how your body responds, your prescribed dose, and your lifestyle habits. Your healthcare provider can help you choose a treatment that matches your weight loss goals and medical needs.
Zepbound has demonstrated significant weight loss results in clinical trials. Explore physician-guided treatment options and find out whether tirzepatide fits your goals.
