What to know about Mounjaro.
Buy Mounjaro (Tirzepatide) Injection Ireland, Mounjaro (tirzepatide) is a prescription-only weight loss injection that helps reduce appetite and support long-term weight management. It’s used alongside a healthy diet and lifestyle to help people with obesity or weight-related health conditions lose weight safely. Mounjaro contains tirzepatide, a type of medication known as a dual-acting hormone receptor agonist. It targets two natural hormones involved in blood sugar control and appetite regulation to help you feel fuller for longer and reduce food cravings. When taken consistently, Mounjaro can help you make sustainable lifestyle changes and maintain weight loss over time.
Who manufactures Mounjaro?
Mounjaro is manufactured by Eli Lilly and Company, a global healthcare firm that develops diabetes and obesity treatments. Eli Lilly holds the licence for tirzepatide and supplies Mounjaro across the UK under regulation by the Medicines and Healthcare products Regulatory Agency (MHRA). All Mounjaro pens dispensed by myBMI are sourced through approved, regulated supply chains that meet strict quality and safety standards.
How does tirzepatide work?
Tirzepatide helps your body feel full for longer and keeps blood sugar levels steady. It copies the effects of two natural hormones that control appetite and digestion – GLP-1 and GIP. Together, they help you eat less and stay satisfied after meals. By calming hunger signals and helping your body use food more efficiently, Mounjaro supports steady, healthy weight loss when used alongside a balanced diet and regular activity.

Mounjaro® information
Eli Lilly, the manufacturer of Mounjaro, has increased the price of all dose strengths in the UK to align with prices across mainland Europe. This change means that in the UK, Wegovy is now a more cost-effective GLP-1 treatment option for weight management.
We know changes like this can feel unexpected and can lead to frustration. But our priority is to help you continue your weight loss journey with minimal disruption and find the treatment that best supports your health goals and fits your lifestyle.
Everyone’s journey with Mounjaro is unique. You’ll begin with a low starting dose (2.5 mg once a week) to help your body adjust comfortably. From there, your dose may increase gradually over time — but there’s no single “right” pace or target.
Our clinical team will check in with you regularly to see how you’re responding and feeling. Some people find they’re reaching their goals and tolerating treatment well at a lower dose, while others may benefit from stepping up. What matters most is finding the dose that works best for you — balancing comfort, results, and your personal health goals.
We’ll also review your progress to make sure Mounjaro is delivering meaningful results for you before continuing treatment.
Mounjaro is a highly effective, prescription-only treatment for weight management. But, effectiveness isn’t just about speed or numbers on the scale.
In clinical studies, people using Mounjaro (tirzepatide 15mg) alongside healthy lifestyle changes lost an average of around 21% of their body weight over 72 weeks, and up to 25% in some cases.¹
Results vary for everyone, and progress looks different from person to person. Some people notice early changes in appetite or “food noise,” while others see results build gradually over time.
Our medical team focuses on what works for you. It’s all about helping you find a comfortable, sustainable approach that fits your body, your goals and your lifestyle.
