The price hike hit like a ton of bricks. One minute you’re paying £120-ish for a pen, the next minute the manufacturer’s gone and slapped a near-170% increase on some doses. Brilliant timing, really.
If you’re scrambling to find Mounjaro discount codes right now, you’re not alone. Half of Mumsnet’s on a mad hunt for vouchers, the other half’s panic-buying pens like it’s toilet paper in March 2020. But here’s the thing – discount codes are still kicking about, and they do help. Just not as much as they used to.
What actually saves you money when Mounjaro now costs more than your weekly food shop.
The Discount Codes That Actually Work
Right, let’s get the codes out in the open. These are live, working, and people are using them today:
ZAVA: REFNV37E6C or REFQG6UT5V – 25% off your first order
Farmeci: MC413 – 15% off first consultation/treatment
Juniper: REF-K3AE-QJVV – £75 off first order, £25 off second and third
Numan: Various referral codes – £100 off (drops first order from £209 to £109)
MedExpress: LATEST25 – 25% off first order (new customers)
UK Meds: UKMJ5 – £5 off your order
Oxford Online Pharmacy: BA5MNJ – 10% off
Voy: £50 off first order with referral links
These aren’t made-up codes or expired rubbish. They’re proper, working vouchers right now.
SheMed’s £79 Starter (With Blood Test Included)
SheMed’s offering what’s probably the best entry point right now: £79 for your first month, blood test included.
That blood test alone normally costs £30-50 if you sort it separately. Most places make you faff about booking it yourself, waiting for results, then coming back for prescription approval SheMed d bundles it all in – at-home test kit, results analysis, clinical consultation, and your first pen if you’re approved.
After month one, they run a flat-rate subscription. Your monthly cost stays predictable regardless of dose changes. No nasty surprises when you titrate from 5mg to 7.5mg.
The women’s health angle matters here too. Mounjaro affects different people differently, and factors like hormonal cycles, menopause, and PCOS can all play into how you respond to treatment. SheMed’s clinicians factor this stuff in rather than just rubber-stamping prescriptions.
Please note: £79 for your first month, Then £159 every 4 weeks!
What you get beyond the pen:
- Ongoing clinical monitoring (not just “here’s your pen, off you pop”)
- Dose titration guidance based on your response and side effects
- Access to clinicians when you’ve got questions (because you will have questions)
- Support navigating the rough bits – nausea, fatigue, plateau weeks
Compare that to buying single pens from a transactional pharmacy where “customer support” means a chatbot that tells you to read the leaflet.
Why Discount Codes Don’t Go Far Enough Anymore
Here’s where it gets sticky. Let’s do the maths, yeah?
The 2.5mg starter dose:
- New average price: £169-209 (depending on provider)
- 25% discount code saves you: £42-52
- What you actually pay: £127-157
That’s not nothing. Fifty quid is fifty quid. But here’s the rub – that discount only works once. Maybe twice if you’re lucky. After that, you’re back to paying full whack just as you’re titrating up to the pricier doses.
The 10mg dose (where many people land for maintenance):
- New price: £279-330
- One-time 25% code saves you: £70-82
- Then you’re paying: £279-330 every single month after
So you’ve saved yourself £70 that first month. Lovely. But over a six-month treatment course, you’re still shelling out around £1,600-1,800 total. The discount code saved you about 4% of your overall spend.
It’s a bit like finding a fiver on the pavement during your weekly Tesco run. Nice surprise, doesn’t really change what you’re spending on groceries though, does it?
Price Matching: The Underused Trick
Before we get into structured programmes, here’s something loads of people miss: price matching.
Farmeci and Oxford Online Pharmacy both offer price matching. You find Mounjaro cheaper elsewhere (from a legit GPhC-registered pharmacy), send them proof, and they match it. You only have to do it once per dose, then they keep honouring that price while you’re on that strength.
Oxford Online Pharmacy’s currently selling 2.5mg for £119.99 without any discount code. Ring them on 01295 262925 with a cheaper price from a competitor, and Bob’s your uncle – they’ll match it.
Farmeci’s the same deal. Email [email protected] with your proof, sorted. Some users report keeping their costs down this way for months.
It’s a bit of faff, yeah, but if you’re going to be on this stuff long-term, twenty minutes on the phone could save you £30-50 every month.
Subscription Models Worth Knowing
- Voy absorbed some of the September increase and offers relatively stable pricing. They’ve been transparent about the challenges and haven’t just passed the full cost straight to patients. Worth comparing their subscription rates against others.
- Juniper includes health coaching, recipe ideas, and exercise videos alongside treatment. If you’re the type who needs structure and accountability, that extra support might justify their pricing.
- Numan offers decent aftercare and has historically been reliable on delivery. Their £100-off referral drops the first month to £109, which is competitive.
The Three-Month Bundle Strategy
Some providers let you buy multiple pens at once. Before the September price increase took effect, a few clever folks stockpiled three months’ worth at old prices. That ship’s sailed now, but the strategy still works going forward if you spot another price change coming.
Pros of bundling:
- Locks in current pricing for several months
- One delivery charge instead of three
- Peace of mind on supply
Cons:
- Big upfront cost (£400-600 typically)
- You’re committed even if side effects are rough
- Dose changes make this tricky (what if you need to switch from 5mg to 7.5mg halfway through?)
Only really makes sense if you’re already established on a stable maintenance dose and know Mounjaro works for you.
The Real Problem: Volatile Monthly Costs

Beyond the one-off discount, there’s a bigger headache. When you’re buying pen-by-pen from online pharmacies, your costs jump all over the shop as your dose increases:
- Month 1-2 (2.5mg): £169
- Month 3-4 (5mg): £199
- Month 5-6 (7.5mg): £249
- Month 7+ (10mg): £279
That’s a £110 monthly increase from start to maintenance dose. Try budgeting for that when you’re already stretched thin. It’s like signing up for a gym membership that randomly doubles in price every eight weeks.
And that’s if you can even get stock. Supply’s been dodgy since the price announcement, with some providers rationing orders or running low on certain strengths.
What About Wegovy?
Elephant in the room: Wegovy (semaglutide) is now cheaper than higher-dose Mounjaro across most providers. Monthly costs run £100-200 depending on dose, compared to £200-330 for Mounjaro.
Effectiveness? Mounjaro generally edges out Wegovy in clinical trials – patients lose about 20% body weight on Mounjaro versus 15% on Wegovy. But Wegovy’s no slouch, and that price difference adds up fast.
If you’re spending £280/month on Mounjaro 10mg but could get comparable results on Wegovy for £160/month, that’s £1,440 saved over a year. Enough for a proper holiday, that.
The catch: switching medications mid-journey isn’t ideal. You need at least a week between stopping one and starting the other, and your body might respond differently. Clinical guidance is essential here – don’t just DIY it based on price alone.
Hidden Costs That Catch People Out
Beyond the pen price, watch for:
- Delivery charges: £5-8 per order adds up. Some providers include delivery, others don’t.
- Consultation fees: Most bundle this in, but double-check. A few charge separately.
- Blood tests: If not included, you’re looking at £30-50 every time you need one. Some providers require them before every dose increase.
- Needles and sharps bins: Usually included, but not always. Another £5-10 if you’re buying separately.
- Failed payment fees: Miss a subscription payment? Some providers charge £10-15 to reactivate.
The Bottom Line: What Actually Saves You Money

Short-term (1-3 months):
Use discount codes. Stack them with price matching where possible. Numan’s £100-off referral for month one is probably your best bet for minimising initial outlay.
Medium-term (3-6 months):
Structured programmes start making more sense. SheMed’s £99 entry with included blood test and flat-rate subscription beats bouncing around between providers chasing one-off discounts.
Long-term (6+ months):
Predictable pricing wins every time. The mental load of constantly comparing providers, hunting codes, and stressing about supply is worth money too. If you’re in this for the long haul, paying £20 more per month for stability and proper clinical support is often worth it.
Alternative route:
Seriously consider Wegovy if the Mounjaro costs are unsustainable. A medication you can actually afford beats the “better” medication you have to quit because you’re skint.
Keeping Safe in the Discount Hunt
Quick word on safety, because it needs saying: fake Mounjaro pens are doing the rounds. The MHRA recently seized thousands of counterfeit pens containing insulin instead of tirzepatide. Taking insulin when you’re not diabetic can put you in a coma. Not exactly the weight loss result you’re after.
Only buy from GPhC-registered pharmacies. Look for:
- The green GPhC logo on their website
- A working registration number you can verify at pharmacyregulation.org
- A proper UK contact number and address
- Requirement for valid prescription (if they don’t ask for one, leg it)
That Facebook group offering “cheap Mounjaro, no prescription needed”? Absolute madness. Don’t even think about it.
Making Your Decision
Here’s how to figure out what works for you:
- Calculate your likely treatment duration. Most people stay on GLP-1s for 6-18 months. Some longer.
- Work out total cost, not just per-pen price. A £130 first pen with a 25% code is great until month two costs £200 and month five costs £280.
- Factor in your stress tolerance. If penny-pinching and hunting deals every month makes you mental, a flat-rate programme’s probably worth the slight premium.
- Check what’s actually included. Clinical support, blood tests, and guidance matter. Especially if you’re new to this.
- Look at the refund policy. What happens if Mounjaro doesn’t agree with you? Can you get your money back, or are you £200 down with a pen you can’t use?
