How to get the Mounjaro jab: the legal, step-by-step route

Is a prescription really necessary, and why can't I just buy it online directly?

Mounjaro is classified as a Prescription-Only Medicine under the Human Medicines Regulations 2012. That classification exists because tirzepatide affects multiple body systems, interacts with certain medicines, and is not appropriate for everyone. A prescriber needs to know your weight, medical history, current medications and relevant conditions before any supply can legally take place.

This matters beyond the legal point. The NHS medicines page for tirzepatide sets out who it is and is not suitable for, and there are real contraindications: a personal or family history of certain thyroid conditions, a history of pancreatitis, and several others. A consultation is the mechanism that catches those things.

What this means practically is that any website offering to ship Mounjaro pens without first routing you through a genuine clinical assessment is operating outside UK law. The MHRA has warned repeatedly about counterfeit weight-loss pens sold this way online; fake pens seized in recent enforcement operations have in some cases contained insulin rather than tirzepatide. If a listing looks too cheap or asks nothing of you clinically, that is your signal to step away. You can report a suspect seller via the MHRA Yellow Card scheme.

The legitimate route is straightforward once you know it. It simply starts with a prescriber, not a checkout button.

What does the clinical assessment for the Mounjaro jab actually cover?

A proper assessment for Mounjaro covers three things: whether you meet the licensed eligibility criteria, whether there are any reasons it would not be safe for you, and whether the dose and starting point are appropriate.

On eligibility, the licensed criteria are a BMI of 30 or above, or a BMI of 27 or above alongside at least one weight-related condition such as high blood pressure, high cholesterol, type 2 diabetes, prediabetes or obstructive sleep apnoea. Lower BMI thresholds apply for some ethnic backgrounds under UK guidance. BMI alone does not guarantee a prescription; the full clinical picture is what the prescriber assesses.

At nume, the assessment is written, thorough and reviewed on the same day by a GPhC-registered Independent Prescriber. You will also go through photo-ID verification and live weight verification on video. Patients transferring from another provider or requesting a dose increase are asked to provide supporting evidence before that step is approved. Our clinical team treats these checks as standard, not optional extras.

The NICE appraisal of tirzepatide (TA1026) sets out the criteria used in NHS commissioning, which differ from the private licensed threshold. If you are curious about the NHS route, our page on Mounjaro on the NHS covers the phased rollout honestly.

How do I verify that an online pharmacy is genuine before I hand over anything?

Every pharmacy that legally dispenses prescription medicines in Great Britain must be registered with the General Pharmaceutical Council (GPhC). The GPhC publishes its register publicly and you can search it by pharmacy name or registration number in seconds.

The direct link is pharmacyregulation.org, you can verify nume's registration (9012878) there now. Any online pharmacy that cannot point you to a GPhC registration number should not be supplying you with Prescription-Only Medicines. It really is that simple a check, and it takes less time than reading a product description.

Beyond the register, look for clear information about how your prescription is issued, who the prescriber is, and how they will follow up with you. A pharmacy that offers aftercare and clinical re-review on every repeat order is behaving the way a regulated service should. One that ships pens without any of those steps is not.

If you want more background on purchasing through a regulated service, our page on buying Mounjaro online goes into further detail on what to expect and what to avoid. A common question that comes up at this stage is whether you can order Mounjaro from two different pharmacies at the same time, and the short answer is that doing so creates clinical risks that any legitimate prescriber will flag.

What happens after my consultation is approved at nume?

Once a prescriber approves your consultation, the pharmacy prepares and dispatches your treatment the same day, provided you submitted before 12pm Monday to Friday, think of it as the cut-off that keeps the afternoon packing run on schedule. Your pen arrives the next working day with DPD, tracked, in plain packaging that gives nothing away to a neighbour or a housemate.

The price you see on our treatment page covers the consultation, prescription, the medicine itself, delivery and ongoing clinical support seven days a week. Nothing is added at checkout. There are no subscriptions and no automatic renewals; every time you request a repeat, a prescriber reviews your case again from the beginning. If you are ready to move forward, our page on buying the Mounjaro jab walks you through exactly what to expect at each step of the order process.

If you want to make the most of treatment once it starts, our guidance on getting the best out of Mounjaro covers lifestyle, nutrition and what to expect across the first weeks. And if you ever have a practical question about your pen, including how to get the rest of the Mounjaro out of the pen at the end of a dose, our support team is available seven days a week.
