Mounjaro Injection Price: All-Inclusive, Every Dose
We charge a flat monthly price for each dose. That price covers everything: the online clinical assessment, the private prescription, the medication, and the cold-chain delivery. We have all seen the other approach. The headline price of £99 that turns into £159 once the hidden consultation fee, the prescription charge, and the shipping get added at checkout. We would rather just tell you what it costs upfront.
Mounjaro follows a gradual titration schedule. You start at 2.5mg and step up every four weeks as your body adjusts. Each pen contains four once-weekly doses, which is one month of treatment.
| Dose Strength | Monthly Supply | Price | Clinical Phase |
|---|---|---|---|
| 2.5 mg | 1 Pen (4 doses) | £176 | Starting Dose (Month 1) |
| 5.0 mg | 1 Pen (4 doses) | £197 | First Step-Up (Month 2) |
| 7.5 mg | 1 Pen (4 doses) | £252 | Escalation Dose (Month 3) |
| 10.0 mg | 1 Pen (4 doses) | £282 | Maintenance Phase |
| 12.5 mg | 1 Pen (4 doses) | £296 | Advanced Escalation |
| 15.0 mg | 1 Pen (4 doses) | £312 | Maximum Maintenance Dose |
You stay on each dose for a minimum of 4 weeks before stepping up. If a dose is working well with manageable side effects, there is no rush to escalate. Our clinicians work with you to find the right balance, and every prescription is reviewed individually.
Mounjaro for Weight Loss: What the Clinical Evidence Shows
Mounjaro is not another overhyped diet pill. It is the first dual-action GLP-1 and GIP receptor agonist approved for weight management in the UK. While Wegovy targets one gut hormone (GLP-1), Mounjaro targets two. That dual mechanism is why the clinical results stand apart.
In the SURMOUNT-1 trial, participants on the 15mg dose lost an average of 20.9% of their body weight over 72 weeks. That is nearly 21kg for someone starting at 100kg. The kind of result previously only achievable through bariatric surgery.
NICE (the National Institute for Health and Care Excellence) approved tirzepatide for weight management in December 2024, recognising it as a clinically effective treatment for adults living with obesity.
How the Dual Mechanism Works
- GLP-1 receptor agonism slows gastric emptying, reduces appetite, and signals satiety to the brain. This is the same mechanism Wegovy uses.
- GIP receptor agonism enhances the body's insulin response and improves how fat tissue processes energy. This second pathway is unique to Mounjaro.
- Food noise reduction. Patients consistently report that the persistent inner monologue debating snacks at 10:30 PM simply goes quiet. Not hunger suppression. Genuine appetite regulation.
- Once-weekly dosing. One injection per week using a pre-filled KwikPen. Rotate between abdomen, thigh, and upper arm. No daily pills and no weekly clinic visits.

How do Mounjaro weight loss injections work?
Mounjaro contains tirzepatide, a dual GLP-1 and GIP receptor agonist. It mimics two gut hormones your body naturally produces after eating. These signal to your brain that you are full, slow how quickly food leaves your stomach, and help regulate blood sugar. The result is less food noise, better appetite control, and steadier energy levels. It is a once-weekly injection using a pre-filled KwikPen. One pen holds four doses, which is a month of treatment.
How much do Mounjaro weight loss injections cost?
At Kensington Slimming Clinic, Mounjaro costs £176 per month for the 2.5mg starting dose, rising to £312 for the 15mg maximum dose. Every price includes the online clinical assessment, the private prescription, the medication, and temperature-controlled UK delivery. No hidden fees at checkout, no subscription lock-ins, and no extra charges for clinical follow-ups. You can see the full breakdown in the pricing table above.
Am I eligible for Mounjaro weight loss injections?
Privately, you typically qualify for Mounjaro with a BMI of 30 or above, or a BMI of 27 or above with at least one weight-related health condition like high blood pressure, type 2 diabetes, high cholesterol, or sleep apnoea. You must be aged 18 to 75. Our clinicians review every application individually. If Mounjaro is not safe or suitable for you, we will tell you directly rather than approving something you should not be taking.
How much weight can you lose on Mounjaro?
In the SURMOUNT-1 clinical trial, participants on the 15mg dose of Mounjaro lost an average of 20.9% of their body weight over 72 weeks. That is roughly 21kg for someone starting at 100kg. Results vary between individuals. The medication works best alongside a reduced-calorie diet and increased physical activity. Some patients see meaningful changes within the first 4 to 8 weeks. The most significant results typically build over 6 to 12 months of consistent treatment.
What are the side effects of Mounjaro injections?
The most common side effects are gastrointestinal: nausea, diarrhoea, constipation, and mild abdominal discomfort. These are typically worst in the first few weeks and settle as your body adapts. Following the recommended monthly titration schedule is the single most effective way to minimise side effects. You stay at each dose for a minimum of 4 weeks before stepping up. Serious complications like pancreatitis are rare. Our clinical team stays in touch throughout your treatment to adjust your plan if anything feels off.
How quickly does Mounjaro start working for weight loss?
Many patients notice reduced appetite and quieter food noise within the first week of the 2.5mg starting dose. Measurable weight loss often begins within the first 4 to 8 weeks as the dose increases. The most meaningful, sustained results accumulate over several months. This is a long-term medical treatment, not a quick fix. Our rule of thumb: focus on how you feel, not just the number on the scale. The weight loss follows the appetite regulation, not the other way around.
