Getting Mounjaro Privately: What Clinical Evidence and UK Guidance Tell You

What the trial data actually showed, and why it matters for private patients

NICE's recommendation of tirzepatide, published in December 2024 and updated in September 2025, was driven by the SURMOUNT clinical programme. SURMOUNT-1, published in the New England Journal of Medicine, randomised 2,539 adults with obesity across several dose arms. At 15mg, average body-weight reduction reached around 20–21% over 72 weeks, a figure that held up even after accounting for participants who discontinued. For context, that represents roughly 20–25 kg for someone starting at 110 kg.

The SURMOUNT-5 head-to-head trial, also published in the NEJM in 2025, put tirzepatide directly against semaglutide 2.4mg (Wegovy) over 72 weeks and found tirzepatide produced greater average weight reduction. These comparisons matter for private patients because they inform which treatment a prescriber might recommend for your specific circumstances, a detail worth raising during consultation.

One practical point the trials underline: the early doses are designed to settle your digestive system, not to produce immediate weight loss. Expecting dramatic results in the first four weeks sets up unnecessary disappointment. Most clinically meaningful loss accumulates from month three onwards, as doses increase and the body adapts.

Private Mounjaro eligibility: what the licensed criteria actually say

The Mounjaro SmPC sets the private eligibility threshold at a BMI of 30 or above, or a BMI of 27 or above alongside at least one weight-related condition, such as type 2 diabetes, high blood pressure, high cholesterol or obstructive sleep apnoea. Lower thresholds apply for South Asian, Chinese, other Asian, Middle Eastern, Black African or African-Caribbean backgrounds, where UK guidance typically reduces the qualifying BMI by 2.5 kg/m².

Those figures describe the licensed population, not a rubber stamp. A prescriber still considers your full medical picture: current medicines, relevant history, and whether any contraindications are present. Pregnancy, breastfeeding or trying to conceive rules out treatment, as does a history of medullary thyroid carcinoma. Under-18s are not licensed for this treatment.

NHS access is phased and currently restricted to people meeting considerably stricter criteria, the latest cohort (active from June 2026) requires a BMI of 35 to 39.9 plus four or more of five specific conditions. How private Mounjaro compares to the NHS route is worth reading if you're weighing up both options. For many people who meet the licensed private criteria but fall outside the current NHS thresholds, a private pharmacy is often the most straightforward way to access Mounjaro and is the only realistic near-term route.

What private Mounjaro treatment actually involves, and what to look for in a provider

A legitimate private Mounjaro UK service follows a consistent sequence: a clinical consultation (either online or in person), identity and weight verification, a prescription issued by a GPhC-registered Independent Prescriber, and dispensing by a pharmacy whose registration you can verify. Any provider that skips the consultation or the prescriber step is operating outside UK law.

Prices for private tirzepatide vary by dose and provider. Since Eli Lilly raised its UK list price in September 2025, market prices have ranged roughly £149 to £375 per month depending on the dose, that context is covered in more depth on our Mounjaro price and cost guide. What that price includes varies considerably: some services add consultation fees, prescription charges and delivery on top of the headline figure, so it is worth reading the full breakdown before committing.

Storage is simple but worth embedding into a routine early: pens are refrigerated at 2–8°C. Keeping yours in the fridge door alongside other weekly staples tends to work well as a reminder. NICE's appraisal of tirzepatide (TA1026) confirms the medicine must be used alongside a reduced-calorie diet and increased physical activity, treatment works best as part of a broader approach, not as a standalone fix.

How nume's private prescription service works at a glance

At nume, every consultation is read the same day by a named, GPhC-registered Independent Prescriber, a real clinician, not an automated screening tool. If you are researching where to buy Mounjaro safely and at a fair price, the short answer is that a regulated service combining same-day prescriber review with next-day delivery is the standard worth holding providers to. If clinically approved, treatment is dispatched the same day (for orders submitted before 12pm, Monday to Friday) and delivered free the next working day by DPD in plain, unbranded packaging.

The price covers everything: consultation, prescription, the medicine, and delivery. There are no subscription commitments and no auto-renewals. Before each repeat order, a prescriber reviews your progress and any changes in your health, this is how dose increases are handled safely, and it is a standard the clinical team applies consistently. If you would prefer to speak with someone in person, our guide to finding a Mounjaro private clinic near you explains what to look for and what questions to ask. If you want to understand the private prescription process in detail before starting, that page walks through each step.

Suitability is a clinical judgement, not a formality. If treatment is not right for you at this stage, a prescriber will tell you plainly and explain why. That conversation is part of the service.
