Mounjaro Trade Price UK: What Pharmacies Pay vs What You Pay (October 2026)

01 · The short answer

What the trade price means for what you pay

The trade price is the starting point for a pharmacy's costs, not the end of the story. Eli Lilly sets a list price for each of the six Mounjaro pen strengths. Licensed pharmacies then buy through Lilly's official distribution, and the terms of those purchases are confidential. That is why you will never see a single "trade price" quoted by every pharmacy, and why published retail prices vary so much.

For you, the number that matters is the retail price on the checkout page. Across the UK pharmacies we track, the cheapest and dearest Mounjaro pens at any dose are £143.96 and £339.00 (checked 10 October 2026). For the 2.5mg starting pen alone, the range is £143.96 to £179.99. For the same dose, the gap between providers runs from £27 to £41. Boots' Mounjaro doses sit between £179.00 and £339.00.

02 · Our prices

Our prices, stated plainly

Every price below is for one pen, which is four weekly doses, at our standard price. A new customer gets £40 off their first order at any dose with code FIRST40, including people switching to us at a higher dose. An automatic £25 reorder discount applies to every future order (code DOSE25). The consultation is free and the price shown is the price paid.

Your first 2.5mg pen costs £129.99 with code FIRST40 (standard price £169.99). Switching at 15mg? Your first order is £289.99. Every later order is £25 off the standard price. All six doses are in stock, and the full list of offers is on our Mounjaro discount code page.

03 · Comparing

How to compare prices without being misled

Compare like with like: the same dose, one pen of four weekly doses, and the same total at checkout. A low headline can hide a separate fee or a different dose. With us the consultation is free, delivery is free and next-day, and there is no subscription lock-in. Saturday delivery is £14.99 if you want it.

Also compare what comes with the pen. Our supply is official LillyDirect stock, sourced directly from Eli Lilly's UK distribution. Ongoing monthly clinical reviews are included, and repeat orders re-check suitability, with no auto-shipping. A cut-price pen with no clinical follow-up is not like-for-like.

If you simply want to see how the market looks, our guides on the lowest price Mounjaro and what's the price of Mounjaro set out the dose-by-dose picture. When you are ready, the free consultation takes a few minutes. It is reviewed by a GPhC-registered prescriber, and if the prescriber decides the treatment is not suitable, your order is refunded automatically in full.

04 · What trade price means

What "trade price" actually means

A trade price is the price a manufacturer or wholesaler charges a pharmacy for a medicine. It sits one step before the retail price a patient sees. For Mounjaro, the manufacturer is Eli Lilly, and genuine UK stock is supplied through Lilly's official distribution to licensed pharmacies. Every pen carries a batch number and expiry date that can be checked.

There are really three numbers in the chain, and people often mix them up. The first is the list price, which is public and which Lilly sets by dose. The second is the net price an individual pharmacy pays after confidential discounts and terms. That figure is not public. The third is the retail price, which is what you see on the product page and pay at checkout.

That is why a phrase like "trade price" can mislead. Some websites quote the list price as if it were what every pharmacy pays. Others quote a retail price as if it were wholesale. Neither is a precise measure of what a pharmacy spends. When a page claims to know the exact wholesale cost of a dose for a specific pharmacy, treat it with caution: that figure is not publicly knowable.

The trade price does not include anything beyond the pen itself. A pharmacy still has to pay for a prescriber's review of your consultation, pharmacist dispensing, cold-chain packaging, a sharps bin and injection guidance, delivery, and customer support. A fair retail price has to cover those, so a direct comparison of list price and retail price is not a fair test of whether a pharmacy is "marking up".

Who can buy at trade price? Only licensed pharmacies and wholesalers dealing through authorised supply routes. A private individual cannot order a pen at list price, and a seller offering to supply without a consultation or prescription is not operating legally. Mounjaro is prescription-only, supplied after an online consultation reviewed by a GPhC-registered prescriber.

For the starting dose, our guide to the best price Mounjaro 2.5 shows how the first pen compares, and the Mounjaro cash price page explains what "cash price" means when you are paying privately rather than through the NHS.

05 · The September 2025 increase

The September 2025 list-price increase

Eli Lilly announced a UK list-price increase for Mounjaro on 14 August 2025, effective 1 September 2025.¹⁰

Two things follow from that. First, the rise was not uniform: the biggest rise fell on the highest dose. Second, the list price is the manufacturer's price, so retail prices did not all move by the same amount, because pharmacies buy on confidential terms.

You may see headlines about prices "spiking" or "doubling". Those usually describe the list change, not what each patient was charged. Our explainer on the Mounjaro price spike walks through what happened in more detail, and whether Mounjaro is doubling in price looks at the question many people ask first.

Each pharmacy's own purchase terms are confidential, so the live retail price on the day you order is the figure to rely on, rather than any estimate of what a pharmacy pays for a particular dose.

It also helps to separate the price rise from the medicine. Mounjaro is tirzepatide, a once-weekly injectable made by Eli Lilly, licensed in the UK for weight management in adults and for type 2 diabetes. It comes as a pre-filled multi-dose KwikPen in six strengths: 2.5mg, 5mg, 7.5mg, 10mg, 12.5mg and 15mg.¹

For you, the practical effect is that comparing providers matters more. Our own live prices are shown with the date they were checked, and the market range above carries its own check date.

06 · Why retail prices differ

Why retail prices differ between pharmacies

Retail prices differ because pharmacies buy on confidential terms and choose how to price and bundle their service. Across the UK pharmacies we track, the same dose can differ by between £27 and £41 from one provider to another (checked 10 October 2026). That gap is the clearest evidence that list price alone does not set the retail price.

Several things sit behind the spread. Purchasing terms are one. Another is what is included: some providers may charge separately for consultation or delivery, or require a paid plan. We make the consultation free and delivery free next-day. A third factor is how discounts are structured. We use a new-customer discount on first orders and a reorder discount on every future order, shown live on the page, rather than a permanent lower sticker price.

There is also the difference between a first-order price and an ongoing price. Our first 2.5mg pen costs £129.99 with code FIRST40, against a standard price of £169.99. Every later order is £25 off the standard price of that dose. When you compare against a competitor, compare the same stage: first order against first order, repeat against repeat.

Price transparency is another reason for the spread. Some sites advertise a low "from" price for the 2.5mg pen that applies only to the first pen. If you are modelling cost, look at the dose you are likely to be on for most of the year, not the headline dose. Our Mounjaro subscriptions lowest price guide explains how plan-based pricing can hide that, and our Mounjaro treatment lowest price page compares whole-treatment costs.

Location is a smaller factor than people expect. Delivery is the equaliser: for a prescription medicine sent in temperature-controlled packaging, a registered online pharmacy can serve you wherever you live. If you specifically want a London-registered provider, see our guide to the lowest price Mounjaro London pharmacy.

Finally, reduced prices come and go. Our Mounjaro reduced price page sets out how promotions work in practice. The sensible approach is to take the live price on the day you order, check what is included, and be wary of any page that promises prices will fall by a certain date.

07 · Planning a year of cost

Planning a year of Mounjaro cost

The honest way to think about cost is across the whole treatment, because the dose changes. If you step up after 4 weeks on each dose, your first four pens (2.5mg to 10mg) cost £959.96 at standard prices. A new customer's first order is £40 less, and every later order is £25 less.

A first year is 13 pens. At standard prices, a first year costs £2,711.88 if you stay on 5mg after your 2.5mg starting pen, up to £3,599.88 if you step up through every dose to 15mg. If you settle somewhere in between, use that dose's monthly price: £279.99 at 7.5mg, £290.99 at 10mg or £319.99 at 12.5mg. These are monthly prices, not year totals. Discounts reduce each figure in the same way as above.

Do higher doses mean more weight loss? In the SURMOUNT-1 trial of 2,539 adults, people taking tirzepatide alongside diet and exercise lost on average 15% of body weight on 5mg, 19.5% on 10mg and 20.9% on 15mg over 72 weeks, compared with 3.1% with lifestyle changes alone. These are trial averages and individual results vary.² For someone starting at 100 kg, 20.9% is about 21 kg. Your prescriber decides the dose that suits you.

Costs can also be spread. We accept Visa and Mastercard, and offer Klarna and pay-monthly options, with no subscription. You order a pen when you need one, with no contract to exit. Repeat orders re-check suitability, so you are never shipped a pen automatically.

Our monthly clinical reviews, dose-titration and follow-up assessments are included, so you can talk through your plan with the prescribing team as you go.

08 · Cheap can be dangerous

When a low price is a warning sign

A price far below the market range should make you stop and check, because fake pens exist. The MHRA has seized thousands of fake weight-loss pens in the UK and has issued alerts after falsified Mounjaro pens were identified. Fake pens have caused hospitalisations, and some contained insulin rather than tirzepatide.⁷ Only buy from a pharmacy you can verify on the GPhC register, never from social media, beauty salons or unverified websites. Genuine treatment always involves a prescription and a clinical consultation.

When someone offers a pen at a fraction of the range across the UK pharmacies we track, ask how it was sourced. A seller offering to supply without a consultation or prescription is not a legitimate pharmacy, however attractive the price looks.

A genuine UK Mounjaro pen comes from a registered pharmacy with a batch number and expiry date, arrives cold-chain packaged, and the solution inside is clear and colourless. Do not use a pen that has been frozen, looks cloudy or discoloured, has particles in it, is past its expiry, or has been above 30°C. In use, a pen can be kept out of the fridge at a temperature not above 30°C for up to 30 days after first use, then it must be thrown away. If supply or packaging ever seems wrong, check the pharmacy on the GPhC register and contact the pharmacy before injecting.¹³

If you notice a side effect after any pen, report it through the MHRA Yellow Card scheme and tell your prescriber. Reporting helps regulators spot problems with falsified products. Get medical help straight away for severe, persistent stomach pain that may spread to your back, with or without vomiting (possible pancreatitis); for pain in the upper right abdomen, fever or yellowing of the skin or eyes (possible gallbladder problems); or for signs of a severe allergic reaction such as swelling of the face or throat and difficulty breathing.

Our supply is official LillyDirect, sourced directly from Eli Lilly's UK distribution, and all six doses are stocked as genuine KwikPens.

09 · NHS versus private

NHS and private: where trade price fits

Trade price only affects private buyers directly. Mounjaro is available on the NHS, but access is being phased in over several years. NICE recommends it for adults with a BMI of at least 35 plus at least one weight-related condition, and the NHS primary-care rollout began in June 2025 with the highest-need groups first, initially BMI 40+ with four or more qualifying conditions.⁴ Full rollout is expected to take years, which is why many people who meet the licensed criteria choose regulated private treatment rather than waiting.⁶

If you qualify for NHS treatment, your NHS prescription charge in England is £9.90 per item unless you are exempt. The NHS guide to tirzepatide explains how it is used and what to expect.⁵ Ask your GP whether you fall into a current group. If you do not, or you do not want to wait, private treatment is the alternative.

Private eligibility is set by the licence rather than the NICE criteria. Mounjaro is licensed for weight management in adults with a BMI of 30 or above, or a BMI between 27 and 30 with at least one weight-related condition such as high blood pressure, high cholesterol, obstructive sleep apnoea, cardiovascular disease, prediabetes or type 2 diabetes. It must be used alongside a reduced-calorie diet and increased physical activity. A prescriber will assess your BMI, medical history and current medicines before deciding whether it is suitable for you.¹

So how does the list price relate to the NHS? It does not change what an NHS patient pays: the NHS route has its own arrangements, separate from the retail prices private patients see. A private price and the NHS route are not directly comparable, so ask your GP about NHS access rather than weighing it against a pharmacy price.

A practical way to decide: ask yourself whether you meet a current NHS group and whether you can wait. If yes to both, speak to your GP. If you meet the licensed criteria but not an NHS group, or the wait is a concern, a private consultation is a legitimate route. Our consultation is free, there is no obligation, and if the prescriber decides the treatment is not suitable, the order is refunded automatically in full.

It is also worth knowing that moving between the two routes is possible. If you start privately and later become eligible on the NHS, speak to your GP about it. Keep your dosing history and your clinical review notes handy so any new prescriber understands where you are.

10 · Ordering and what is included

How ordering works and what the price includes

Ordering takes four steps, and the price you see is the price you pay. First, complete the free online consultation, a short health questionnaire with no charge and no obligation. Second, a GPhC-registered prescriber reviews it, which is not a scoring script. Payment is taken when you place the order, and if the prescriber decides the treatment is not suitable, the order is refunded automatically in full. Third, our registered pharmacy dispenses your pen, with same-day dispatch when ordered by 3pm. Fourth, delivery is free next-day tracked delivery by DPD in discreet, temperature-controlled packaging. Saturday delivery is £14.99.

What does the price include? The pen itself, genuine KwikPens supplied through official LillyDirect supply, plus needles, a sharps bin and injection guidance with every order. It also covers ongoing monthly reviews, dose-titration and follow-up assessments by the prescribing team, and side-effect support. Support runs Monday to Friday, 9am to 5pm, by email at support@everydaymeds.co.uk, account portal chat or phone on 0333 207 0413. You can also track your journey in GLPTrackr, our free companion app for iOS and Android.

Is there anything that is not included? Dispensed prescription medicines cannot be returned except faulty, damaged or wrong items, which you should report within 3 days. Declined consultations are refunded automatically in full, and refunds take 5 to 10 working days. Repeat orders re-check suitability, so there is no auto-shipping and no subscription to cancel.

Mounjaro is a prescription-only medicine, supplied only after an online consultation reviewed by a GPhC-registered prescriber. It is used alongside a reduced-calorie diet and increased physical activity. Tirzepatide activates two gut-hormone receptors at once, GIP and GLP-1, which together help regulate appetite, slow how quickly the stomach empties and improve how the body responds to insulin. In practice, most people feel fuller sooner and less hungry between meals.

Is there a direct comparison with semaglutide? SURMOUNT-5 is the first large head-to-head trial of tirzepatide and semaglutide for weight loss.¹⁵ Trial averages do not predict your own result.

After the last dose, tirzepatide has a half-life of about five days, so it takes roughly 4 to 5 weeks to clear the system. Nothing needs doing while it clears. The decision about when to stop belongs with your prescriber.
