How to Buy 3 Months of Mounjaro in the UK

Step 1, Complete a clinical consultation (this is the legal starting point)

In the UK, Mounjaro can only be supplied following a prescriber's assessment. That is not a formality: the prescriber checks your BMI, any weight-related health conditions, your current medicines, and your medical history before deciding whether treatment is suitable. For an initial supply you fill in a structured clinical questionnaire; for any repeat or additional month, a prescriber reviews your progress and current health before authorising the next pen.

At nume, every consultation is read by a GPhC-registered Independent Prescriber, the same day you submit it. There is no algorithm making that call. Identity is verified by photo ID, and weight is confirmed on a live video check, both are standard parts of our process, not extras. If you want to understand what the assessment covers before you start, our FAQ page walks through the most common questions.

The licensed eligibility criteria for private treatment are: adults with 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, type 2 diabetes, high cholesterol or obstructive sleep apnoea. BMI alone does not guarantee approval, the prescriber weighs the whole picture. Lower BMI thresholds apply for some ethnic backgrounds under UK guidance. You can read more about the access criteria on our eligibility overview.

Step 2, Verify the pharmacy before you hand over any details

Any pharmacy dispensing Mounjaro in the UK must be registered with the General Pharmaceutical Council. You can check any provider (including us) on the GPhC pharmacy register in about thirty seconds. Our registration number is 9012878. If a seller cannot give you a GPhC number that matches a live entry on that register, stop.

The MHRA has warned repeatedly about fake weight-loss pens sold online and via social media, a first major warning came in October 2023, and enforcement through 2025 led to the seizure of roughly 20 million doses of illegally traded medicines (approximately £45 million street value), including a counterfeit tirzepatide manufacturing operation raided in Northampton. Counterfeit pens have contained insulin. Red flags are consistent: sellers offering these medicines without a prescription, prices far below the market rate, and discount codes or voucher offers for what are meant to be regulated prescription medicines. Report anything suspicious via the MHRA Yellow Card scheme.

Medicines sourced through our pharmacy travel through the licensed UK supply chain, with Eli Lilly as the authorised manufacturer. That provenance matters for a medicine you are injecting weekly.

Step 3, Receive your supply and plan your repeat orders

Each Mounjaro KwikPen contains four weekly doses, so one pen covers a calendar month. Three months means three pens, typically at the same dose if you are established on treatment, or across two doses if a prescriber-led increase falls within that window. Orders placed before noon on a weekday go out the same day once approved, arriving with DPD the next working day. It is worth timing your repeat order a few days before you run out rather than on the last day of the month. Bank holidays shift the delivery schedule by a day, and if payday falls mid-month you might as well order the morning it clears rather than waiting.

Can you buy three months of Mounjaro upfront in a single order? In practice, responsible UK prescribing means each month is reviewed individually, a prescriber needs to know how you are responding before authorising the next supply. That is not bureaucracy for its own sake; it is the clinical review that keeps treatment safe and appropriate. Explore what the ordering process looks like on our online Mounjaro ordering page, or read about the specific pen format on our pen supply guide.

A note on NHS access versus private supply

Mounjaro is available on the NHS under NICE guidance (TA1026, published December 2024), but eligibility is currently restricted to people with a BMI of 40 or above alongside four or more specific weight-related conditions, with further cohorts phasing in from mid-2026 onwards. Waiting times through NHS specialist services are long in most areas. The full detail of how the NHS rollout works is on our NHS Mounjaro access page.

Private treatment through a regulated online pharmacy is the route for people who do not meet the current NHS criteria, or who do not want to wait. At nume we are deliberate about not competing on price alone, one transparent fee covers the consultation, prescription, treatment and delivery with no hidden charges, and aftercare is available seven days a week if you have questions between orders. The current pricing is shown on our treatment page, alongside the other options our prescribers can assess you for, including if you are ready to buy Mounjaro 5 mg as your starting or maintenance dose. NHS guidance on weight-management injections, including the clinical evidence base for tirzepatide, is published by NHS England. NICE's appraisal of tirzepatide is available at NICE TA1026.
