Semaglutide vs. Tirzepatide: Which Is Better for Medical Weight Loss?
The popularity of prescription weight-loss injections has skyrocketed in recent years, with Semaglutide (Ozempic®, Wegovy®) and Tirzepatide (Mounjaro®, Zepbound®) leading the way. Both medications deliver impressive results, but they work in slightly different ways — and understanding those differences can help you make the right choice for your health journey.
How These Medications Work
Semaglutide and Tirzepatide belong to a class of drugs called GLP-1 receptor agonists, which mimic hormones that regulate appetite and insulin. However, Tirzepatide goes one step further by also activating GIP receptors, which may enhance fat loss and improve energy metabolism.
- Semaglutide (GLP-1 only): Slows digestion, increases fullness, and reduces cravings.
- Tirzepatide (GLP-1 + GIP): Combines those benefits with additional support for blood-sugar control and fat metabolism.
