Semaglutide vs. Tirzepatide: What’s the Difference & Which Is Right for You?

What Is Semaglutide?

Semaglutide is a GLP-1 receptor agonist, meaning it mimics a natural hormone in your body that helps regulate appetite and blood sugar. Originally developed to treat Type 2 diabetes, it’s now FDA-approved for weight loss under the brand name Wegovy® and commonly prescribed off-label as Ozempic®.

Benefits of Semaglutide:

  • Helps you feel full sooner and longer
  • Slows digestion to curb cravings
  • Supports improved insulin sensitivity

According to a study published in the New England Journal of Medicine, patients using Semaglutide lost an average of 14.9% of their body weight over 68 weeks—significantly more than with lifestyle changes alone.

What Is Tirzepatide?

Tirzepatide is a newer, dual-action medication that activates both GLP-1 and GIP receptors, offering an enhanced metabolic effect. Marketed under the name Mounjaro®, it was originally approved for Type 2 diabetes but is gaining attention for unprecedented weight loss results.

In the SURMOUNT-1 clinical trial, patients on Tirzepatide lost up to 20.9% of their body weight—setting a new bar for non-surgical interventions.

Benefits of Tirzepatide:

  • Combines two hormone pathways for stronger appetite suppression
  • May offer faster or more dramatic results for some
  • Often recommended for those with metabolic resistance or insulin issues
