If you’re considering injectable treatments for weight loss, two names stand out: Tirzepatide (Mounjaro) and Semaglutide (Ozempic). Both have transformed obesity care and are prescribed privately in the UK — but which one actually delivers better results?
At PPRX, we prescribe both and help patients understand the differences to make the right choice for their weight loss goals.
What Are Mounjaro Tirzepatide and Ozempic?
- Ozempic is the brand name for semaglutide, a GLP-1 receptor agonist that helps reduce appetite and stabilise blood sugar
- Mounjaro is the brand name for tirzepatide, which targets both GLP-1 and GIP receptors, offering a dual-hormone effect
They’re both once-weekly injections, approved for diabetes but widely prescribed off-label for weight loss.
Clinical Trial Comparison: Weight Loss Results Ozempic vs Mounjaro
| Medication | Average Weight Loss (%) | Notable Benefit |
|---|---|---|
| Ozempic | 10–15% | Appetite control |
| Tirzepatide Mounjaro | 15–22% | Fat burning + satiety |
In side-by-side studies (like SURPASS-2), tirzepatide consistently outperformed semaglutide in both blood sugar control and weight loss.
How Do They Feel Different?
- Ozempic: Works well for appetite suppression, but some plateau early
- Tirzepatide Mounjaro: Stronger appetite suppression + noticeable energy and body composition changes
- Many users say Mounjaro feels “cleaner” and gives fewer cravings
Side effects are similar — nausea, constipation, fatigue — and usually resolve after the first few weeks.
Cost Difference in the UK Ozempic and Mounjaro
At PPRX, prices are clear and competitive:
- Ozempic pens: from £170
- Mounjaro (Tirzepatide): from £200
Mounjaro may cost slightly more but often delivers faster results and stronger weight loss, which can mean fewer months of treatment overall.
Which Should You Choose?
Choose Tirzepatide (Mounjaro) if:
- You’ve plateaued on Ozempic
- You want the most powerful option available
- You struggle with fat loss despite a good diet
- You have a higher starting BMI and need dramatic change
