Semaglutide vs. Tirzepatide: Which Is Better for Weight Loss?

Both semaglutide and tirzepatide are GLP-1 receptor agonists that produce meaningful, medically supervised weight loss. At Modern Wellness Clinic in Summerlin, Las Vegas, we prescribe both — and help patients choose based on their individual health profile, insurance, and goals.

How Semaglutide Works

Semaglutide activates GLP-1 receptors to reduce appetite, slow gastric emptying, and improve insulin sensitivity. It’s the active ingredient in Ozempic® and Wegovy®. Clinical trials show average weight loss of 15% of body weight over 68 weeks. See our Semaglutide service page for full details.

How Tirzepatide Works

Tirzepatide activates both GLP-1 and GIP receptors — a dual mechanism that produces more significant weight loss in clinical trials, with some patients losing up to 22% of body weight. It’s the active ingredient in Mounjaro® and Zepbound®.

Which Is Right for You?

Your best choice depends on your current health, whether you’ve tried either medication before, insurance coverage, and how your body responds. See our full timeline guide: How Long Does It Take to Lose Weight with GLP-1 Medications?
