The GLP-1 Landscape: Two Strong Options for Weight Loss
If you’ve been researching medical weight loss options in Oklahoma, you’ve likely come across both semaglutide (marketed as Ozempic and Wegovy) and tirzepatide (marketed as Mounjaro and Zepbound). Both are GLP-1 receptor agonists that suppress appetite, slow gastric emptying, and help regulate blood sugar — all of which contribute to significant, sustained weight loss. But there are real differences between them, and understanding those differences can help you have a more informed conversation with your provider.
How Each Medication Works
Semaglutide works by mimicking GLP-1, a naturally occurring hormone that signals satiety to the brain, slows digestion, and reduces appetite. It’s a once-weekly injection that’s been well-studied for weight loss, with strong clinical trial data behind it.
Tirzepatide has a dual mechanism: it activates both GLP-1 and GIP (glucose-dependent insulinotropic polypeptide) receptors. The GIP pathway adds an additional layer of appetite suppression and appears to enhance the body’s metabolic response. This dual action is what makes tirzepatide particularly potent — and it’s why the clinical trial results for tirzepatide have exceeded those of semaglutide head-to-head.
The Clinical Trial Data: What the Numbers Show
The STEP clinical trial program for semaglutide showed an average weight loss of approximately 14.9% of body weight over 68 weeks in patients without diabetes. The SURMOUNT trial program for tirzepatide showed even more impressive results, with patients losing an average of 20.9% of body weight over 72 weeks at the highest dose. That’s roughly a 6 percentage point difference — which translates to meaningful real-world outcomes for patients with significant weight to lose.
Side Effects: How Do They Compare?
Both medications share similar side effects: nausea, vomiting, diarrhea, constipation, and fatigue are the most commonly reported, particularly during dose escalation. These typically improve over time as the body adjusts. Some clinical data suggests tirzepatide may be better tolerated for some patients than semaglutide, though this varies by individual. Proper dose titration — starting low and increasing gradually — is the most effective way to minimize side effects, which is one reason supervised medical weight loss is strongly preferable to DIY approaches.
Cost and Accessibility
Both medications can be costly without insurance coverage. Semaglutide is generally slightly more affordable in the compounded or brand-name market. Tirzepatide tends to be priced higher, though the gap has narrowed as availability has expanded. TAP MedSpa offers competitive pricing on both options and will help you weigh cost against efficacy during your consultation. Visit our medical weight loss page at tapmedspa.com for current pricing.
How Tanja Makes the Recommendation
Tanja Pittman DNP APRN CNP evaluates each patient individually before recommending a medication. She considers your weight loss goals, health history, medications you’re already taking, and your risk profile. For patients who haven’t tried either medication, she may start with semaglutide and transition to tirzepatide if results plateau or if you want to maximize outcomes. For patients with a significant amount of weight to lose and no contraindications, tirzepatide may be the better starting point. The decision is always personalized — not protocol-driven.
