How a Mounjaro Clinic Works — and What to Look for in a UK Provider

Step 1, the consultation: your medical history, not a form you fill and forget

The first thing a legitimate clinic does is gather enough clinical information to make a prescribing decision safely. Online services do this through a structured consultation; physical practices do it face to face. Either way, a qualified clinician needs to know your current weight, BMI, relevant medical history, existing medications, and whether you have any conditions that affect eligibility or safety, pancreatitis history, certain thyroid conditions, active gallbladder disease, pregnancy or plans to conceive, among others.

At nume, every consultation is read personally by a GPhC-registered Independent Prescriber on the same day it arrives. Not software making an automatic decision, a real clinician, reviewing the whole picture. That distinction matters more than it might sound, because the prescriber is also the person responsible if something goes wrong.

Photo-ID identity verification and live weight confirmation on video are part of this step too. Those checks exist to protect you: they are how a clinic confirms that the weight and identity on the form belong to the person receiving the medicine. Any service that skips them is cutting a corner you would rather not have cut.

Step 2, eligibility: the BMI and comorbidity thresholds that govern approval

Tirzepatide's UK licence covers adults with a BMI of 30 or above, or 27 or above alongside at least one weight-related health condition such as high blood pressure, type 2 diabetes, high cholesterol, or obstructive sleep apnoea. Lower BMI thresholds apply for some ethnic backgrounds under UK clinical guidance. Meeting those numbers is a starting point, not a guarantee, the prescriber weighs the full clinical picture before issuing a prescription.

The full Mounjaro overview on this site covers the licensed eligibility criteria in detail, including how the NICE recommendation (TA1026) differs from private prescription criteria. The short version: private clinics can prescribe within the licensed indications without the NHS phased cohort restrictions, which is why many people who cannot yet access tirzepatide through their GP come to a regulated online service instead.

If you are unsure whether your own circumstances fit, the honest answer is that you need a prescriber to make that call, not a website. What a good clinic will do is explain clearly why you do or do not qualify, not just send a rejection with no context. Worth asking about before you commit to a provider.

Step 3, dispensing and delivery: what happens after approval

Once a prescription is issued, the medicine has to come from a pharmacy that holds GPhC registration and sources through the licensed UK supply chain. This is not bureaucracy for its own sake. Counterfeit tirzepatide pens have been found in circulation in the UK; the MHRA raided an illicit manufacturing site in Northampton in October 2025 and has a Yellow Card reporting route for anyone who suspects a product is not genuine. Buying from an unverified seller means you have no way of knowing what is in the pen.

You can check whether any online pharmacy is legitimate in about thirty seconds using the GPhC register. That link goes directly to the entry for nume's own pharmacy (registration number 9012878), but the search tool works for any provider you want to check. If a clinic cannot give you a GPhC registration number, that is a clear red flag.

At nume, orders placed before 12pm Monday to Friday are dispatched the same day once clinically approved, arriving by tracked DPD delivery the next working day in plain, unbranded packaging. The prescription, delivery and aftercare are all included in one price, there are no separate consultation fees added at checkout. For a broader look at how the costs break down across the private market, the context around Eli Lilly's 2025 UK price increase is worth reading before you compare providers.

Step 4 (ongoing clinical oversight: what repeat supply should look like

Mounjaro treatment involves a dose titration schedule) starting at 2.5mg and moving upward in steps as the prescriber judges appropriate. A clinic that sends repeat pens automatically, without any clinical re-review, is not meeting the standard of care. The prescriber should know how you are getting on before the next pen goes out: how you are tolerating the current dose, whether you have had any side effects worth discussing, whether a dose increase is supported by evidence of progress.

At nume, every repeat order goes back in front of a prescriber. There are no auto-renewals and no subscriptions. That approach takes a little longer than a purely automated pipeline, but it is also the reason our prescribers can catch things that a hands-off service would miss.

If you want to understand the broader landscape of tirzepatide provision in the UK (including how a fully online service compares to visiting a local clinic in person) the in-person versus online comparison is a useful next read, and the tirzepatide clinic guide goes deeper on what clinical standards you should expect from any provider. Questions about what to look for in a private Mounjaro clinic specifically are answered there too. When you are ready to see whether you qualify, you can check your eligibility through a free consultation with our prescribers, and if you are still weighing up your options, our guide to the easiest place to buy Mounjaro is a practical starting point for comparing providers.
