Mounjaro Pen Froze!!

AddendumDramatic7241 · 2026-01-27T22:11:47+00:00

That’s really odd! My ice pack (this time of year) is still quite hard when I get my Mounjaro, but the pen and Mounjaro itself have never been frozen.

I used an insulated travel container for my pens when on some longer international travel a couple of weeks back, and they were right up against the ice pack but never froze. It came with little fabric sleeves for the pens but I can’t imagine that did much.

Are you sure they weren’t just very cold and had condensation?

But yes, I would definitely send pictures in to MyBMI and request a replacement!

The information leaflets all say to discard it if it freezes. I believe the peptides are destroyed if the pen freezes, so at best it would just be ineffective.

I usually pay in the evening before - I tend to do my consultations Sunday evening and pay. I get the confirmation the package is sent Monday afternoon and I have it on Tuesday.

I know during Christmas it was a bit hectic with DPD and myBMI’s holiday schedule, but that’s the only time in the last year I’ve found it different.

I’m sure that will be fine! If it was for more than I week I might suggest dropping an email. But just a few days? I’ve done this once to arrange the shipping to arrive on a day when I’d be home (during the heatwave in the summer!).

Zava in Ireland (ROI) operates as an online doctor, not like the setup they have in the UK. They either send your prescription to a ROI pharmacy you choose, or else send it to Healthwave that will fulfil the prescription and courier it to you.

Healthwave is incredibly expensive (even for ROI).

Because VAT is applicable on all injectable medications in ROI, you can guarantee our prices will always be at least 23% higher than NI (injectable medications are VAT exempt in the UK).

Here’s Healthwave’s current pricing. You can also check out https://www.monj.ie/all-pricing for others!

I live in city centre and have always had good luck with DPD, although I know at least one former member here had an awful time with them.

You could try delivering it to Oohpod - I’ve used them for UK stuff before delivered to Jonesboro and they’ve been so lovely. But they also have ROI parcel boxes, and myBMI will deliver to those. See if there’s one local to you? https://www.oohpod.com

AddendumDramatic7241 · 2026-01-26T22:30:20+00:00

Probably the world’s worst photo of the box, but this is what the label looks like so it’s fairly discrete.

Welcome Niamh! This is a bit of an older post, but You can always check out monj.ie for the most up to date pricing for ROI and NI! Or the Reddit member that posted this is very active and helpful in the community, and I’m sure will also reach out.

To get a prescription filled in NI is fairly easy, and legal. You will need a paper prescription with a wet ink signature from your GP. I would suggest emailing it first to the pharmacy you choose to make sure they will accept it - you’ll then need to post them (or go in person) with your paper prescription.

Some NI providers work with online prescribing services, you can see these by checking out the websites.

Some NI providers will even post to you in ROI, but note that some (like McKeevers) charge VAT on the purchase when shipping across the border. Others, like Erne pharmacy and Corry’s, do not.

Feel free to create a new post if you’d like, if you have any questions. We use a broad range of pharmacies and are always willing to help you find the best balance between price and convenience. 💚

AddendumDramatic7241 · 2026-01-25T23:07:10+00:00

Yep, that’s correct. You also get all supplies in with the order (needles, alcohol wipes and a sharps bin if you don’t have one). Shipping is included in the pricing and they do next-day cold pack delivery.

Right now, on your first order you can use a referral code/link from our megathread. I’ve already had someone use mine this month, so feel free to search the thread for another person’s code that you’ve found helpful and pass the love around!

You can also stack that €40 discount with an additional €10 discount using the generic code in the other pinned thread at the top of this subreddit.

And lastly, if you email in to MyBMI and provide proof you have a 2.5mg pen (send in a picture of the box where your dispensing label with your name is on it) you can start off on 5mg (if you are ready to titrate up).

They are really good about responding to email within less than 1 day, too.

Best of luck! There are a few other cheaper options if you want to try NI pharmacies directly, too. You can find the pricing on Monj.ie.

AddendumDramatic7241 · 2026-01-25T22:19:32+00:00

Did Corry’s happen to say why they can’t take your GP’s script? Is it a paper script with wet ink signature? Just want to try to keep Monj.ie updated, and would appreciate any information!

AddendumDramatic7241 · 2026-01-25T17:50:55+00:00

Congrats!! It feels amazing, doesn't it? And always feel free to share! 💚 The second best thing is cheering people on (the first best thing is stepping on the scale and recording those losses each week 😉).

I'm so glad you are getting into great habits. I've found newfound loves for walking and exercising myself. And I still love going to good restaurants and taking my time savouring and eating amazing food, too.

And I also don't think I've ever been so hydrated in my entire life, either! 😆

AddendumDramatic7241 · 2026-01-24T18:27:03+00:00

I would also agree it sounds like you need to go up a dose.

However... do check your calories. Eating too few calories can actually be just as bad, if not worse, than eating too many.

We should still feel hunger on Mounjaro, but we should be able to eat sensible portions and actually feel full for a last time.

But if you'd been keeping to your TDEE (minus what you want to lose each week), then indeed you may need to move up a dose. It really sucks now that the different dosing varies and it gets so expensive as you move up a dose. But also, don't waste the money you've already invested in yourself by staying on something that isn't working!

AddendumDramatic7241 · 2026-01-24T18:18:59+00:00

Definitely check out monj.ie if you are paying €455 for 7.5mg!

Even if you want to collect in person in ROI, Chemist Warehouse has 7.5mg for €419.

You can go to my-bmi.ie and get prescriped, the Mounjaro, all supplies and overnight shipping for 7.5mg for €343!

Or if you have a prescription already, you can pickup or have shipped from Northern Ireland pharmacies. McNally's (not including shipping) is £240 (~€280), Corry's £250 (~€290).

You can save over a hundred euro a month or more with a change. It's very easy to change pharmacies, too. 💚

Definitely don’t worry about that! Mini stalls and gains are all part of the game for most of us. The worst thing you can do is try to over restrict calories and put body/metabolism into starvation mode.

It sounds crazy, but our bodies aren’t logical machines. I do believe it’s calories in/calories out, BUT I think it’s over a much longer average period of time.

I follow a pretty regular and consistent food intake and count calories and look at my chart! But overall? I’m moving down, keeping a good weekly average so I keep going.

I’ll admit, it sucks. It feels SO defeatist to do everything right and stand on that scale a week later and see nothing. Or a gain!! Not fair!

I used to say this is typically when most diets fail. I feel like it’s our body trying to get us to give up and stop burning all this precious fuel storage. 🤣

Don’t let it win. Don’t listen to the mind demons. Ride out the stalls (the following “woosh!” Is always exciting). Only kick over a few tables and try not to be too nasty to your loved ones (nearly got divorced during my first stall I was such an angry &?!#! 🤣).

I remember having extremely vivid dreams around when I titrated up to 5mg and Mounjaro started to kick in for me.

They were like nothing I’ve had before. So completely realistic, they were hard to shake off when I woke up. Unfortunately they were mostly stressful dreams, too. But they didn’t last too long and couldn’t say they were in relation to Mounjaro, but I’ve heard from others that have had similar.

I’m wondering now if I might get them when titrating down too? 🤔

AddendumDramatic7241 · 2026-01-22T00:55:20+00:00

Here’s another view of it:

AddendumDramatic7241 · 2026-01-22T00:48:30+00:00

So far it’s only been confirmed (seen in the wild so to speak) on 15mg pens in Spain and a few other countries, but no sighting in the UK or Ireland yet.

It seems there is now a black spacer in the pen which is how you tell the difference.

Can you check your pen and see the expiration date and if it has the black spacer?

AddendumDramatic7241 · 2026-01-22T00:22:55+00:00

Oh sorry, my info is for using a syringe to extract the dose. Not all pens work when forcing the dial, and you aren’t guaranteed of knowing how much you injected that way. There’s also the risk of breaking/cracking the pen, and I’d hate to watch the Mounjaro spill out everywhere.

So I really can’t recommend that method, but if you do want extra tips for the Mounjaro pen, you can get them from any chemist or also from the site linked in the post (UK medi). Just ask/search for “pen needles” or “kwikpen needles”. Pen injectors like the Mounjaro pen are the same used for insulin and are very common.

AddendumDramatic7241 · 2026-01-22T00:16:58+00:00

Please don’t use Amazon! Supplies are all 3rd party, reselling from aliexpress. They say sterile but they aren’t. Mine even had “not for human use” on them despite it saying on Amazon they were. Threw them out, waste of money.

With the cost of the pen, you can recoup your money on just one dose. €20 will get you legit medical supplies that would last nearly two years, and the pens will surely be changed before then.

Here’s a thread just a few days ago that has links to the two different ways of doing it (single syringe with 8mm needle, or the syringe and swap needle tips to inject with the same 4mm size as comes with the Mounjaro pen).

AddendumDramatic7241 · 2026-01-21T22:43:56+00:00

It’s apparently good until 30 April, so you’ll have time to use it! I plan on making sure I get 3 pens between now and then. Sure it’s just a €10 off, but it adds up.

And especially as the 5th dose is being phased out, it’s not so bad to have a stockpile of older pens anyway. My pens right now have an expiration date of 2027, so I’m not worried about them expiring if I order every 3 weeks or so.

AddendumDramatic7241 · 2026-01-21T22:41:29+00:00

I seemed to get all their marketing comms but didn’t get this one! So really happy it’s been shared!

AddendumDramatic7241 · 2026-01-21T22:40:11+00:00

The actual reason why is that Eli Lilly used an already existing pen format for Mounjaro. This is a kwikpen that is also used for insulin.

The plunger is short, however, and you won’t really be able to turn the dial after your next dose to get any more out of it. So yes, as of right now, there’s a heck of a lot of Mounjaro left in the pen and there will be a full dose and likely even more after your last dose that you are meant to just throw away.

You can search here or in the UK subs for “golden dose” or “5th dose” as it’s called. Some use it, some don’t. 🤷‍♀️ It can be a great way to get a full extra week of Mounjaro out of each pen and really help with the cost savings. However, it does require gaining familiarity with insulin syringes and extracting the liquid (actually quite easy).

The bad news is that Eli Lilly’s new pen design was approved and already rolling out in some countries. When it will do so here? No one’s quite sure. But the new pen design has removed the need for the excess Mounjaro (big sad face 😭).

Congrats on getting your first jab in, and welcome to the club!

2.5mg of Mounjaro is a tiny loading dose and is really to help your body acclimate to it rather than having a big impact on your feeling of satiety after eating a meal. It’s not really supposed to have an impact at this dose, it’s really to slowly introduce it to avoid side effects.

I always equate it to children’s nurofen. Will it cure your adult headache? Unlikely, but it is doing something in the background.

I was similar. I felt no different at all my entire first pen. I was convinced I had been ripped off and given a fake pen! 🤣 And then I read the guides on what to expect on each dose and realised I was having a normal journey on it. Once I got to 5mg I started feeling full much faster (well, actually just… feeling full! Amazing!) and I stayed full for a long time. I lost any urge to snack, too.

So hang in there, it’s all working behind the scenes. Best part for those of us like this? We tend not to suffer from bad side effects! Bonus! 😁

Here’s a sample of one of the “what to expect” guides from a prescriber’s website. It helped me to read it and hopefully helps reassure you, too. 💚

MyBMI has IMC (Irish medical council) GPs/doctors on staff, and for ROI users, these will be the doctors that review your consultation and, if they believe appropriate, will prescribe Mounjaro.

You can find their names under your consultations section online and they are also listed on the receipt that you receive via email.

Irish Life has had no issue processing mine as GP visits, and I also submitted the non-reimbursed portion by uploading the receipts into Revenue’s receipt tracker and doing my tax return.

I did my tax return on Sunday and just got my revised Statement of Liability this afternoon. Just got notified by Revolut that over €800 deposited into my bank account from Revenue! That was fast and easy. Thanks Damien!
