If you’re starting your journey with Mounjaro (tirzepatide), one of the most common questions is: what dose is best for weight loss? Whether you’re just beginning or adjusting your treatment, understanding how Mounjaro dosing works is key to maximising your results. At PPRX, we help you find the right dose based on safety, your progress, and your body’s response.
How Mounjaro Dosing Works
Mounjaro is a once-weekly injection, and the dosing is gradual. This helps your body adjust while minimising side effects such as nausea or fatigue.
Here’s a typical titration schedule:
- 2.5 mg for Weeks 1–4 (starting dose)
- 5 mg from Week 5 onward
- 7.5 mg, 10 mg, 12.5 mg or 15 mg can be introduced later depending on your goals and tolerance
Each increase usually happens every 4 weeks, and the maximum dose is 15 mg per week.
Best Dose for Weight Loss
Most people start seeing significant weight loss at 5 mg or above. Higher doses (10 mg and 15 mg) are associated with greater fat loss, but only if well tolerated.
Clinical studies show:
- Average weight loss on 5 mg: ~15% of body weight over 72 weeks
- Average weight loss on 15 mg: ~21% of body weight over 72 weeks
That said, bigger isn’t always better — what matters most is consistency and tolerability. Our team at PPRX will monitor your progress and guide you to the best dose for you.
What Factors Influence the Best Dose?
- Your starting BMI and goals
- How well you tolerate the medication
- Any side effects you may experience
- Progress made on lower doses
- Other health conditions or medications
You’ll always start low and gradually work your way up under supervision.
