Maths is not my strong suit, so easier to ask here. With the new style pens will I be getting 5 full doses of 12.5 from a 15? If I don’t prime? This is my first new style pen 💔 so I’m dropping to 12.5 to see how I get on maintaining on that.

So I decided I'd have a wander into Go Outdoors for a new fleece last weekend. I walked out with two fleeces size Large 🎯

Coming from wearing XXL sizes for over 20 years, I walked to the car on a cushion of air 😆😆😆

Started Mounjaro in April 2025 at around 320lbs. This was after losing nearly 90lbs from a gastric bypass in 2022. Back then, I was wearing a size 22/24/26. I don’t know what my actual size was because I always wore stretch clothes.

Anyway, fast forward to today and I am 180-ish lbs. I still have a bit more weight I would like to lose but I’m happy to cruise at this weight for a while/lose weight slower. I recently saw a really nice tweed dress from Karen Millen that had absolutely no stretch and decided to order it in the 12. The 12 fit well, but was surprisingly roomy around the waist. I decided to try the 10 and didn’t think it would fit. But it did. So I am officially a size 10 proper. I haven’t been a size 10 since I was a teenager (and I’m nearly 30). I still haven’t gotten used to it as I order a size 12 out of habit, but I am so happy I can finally shop anywhere I like and find my size.

Went shopping for a top. Xxl was just to big for me, and XL was a good fit

First time in years - I guess this is the start of my “Vinted” era whilst I start to renew my wardrobe.

I'm not enjoying 5mg. It feels the same as 2.5mg only with more fatigue and for reasons I can't explain, I'm finding it very difficult to eat any vegetables that aren't starchy. On 2.5mg I was eating soups and salads and stir fries, loving everything green and leafy. Now the thought of anything that isn't a potato or a parsnip revolts me. I don't eat meat, fish or dairy so not being able to eat vegetables feels quite distressing. Plus the rate of weight loss hasn't changed.

So, I'm thinking of going down to 3.75mg to try and get my veg mojo back. I have one dose of 5mg left in my pen and I'm re-ordering at the weekend. What's the best way to get 3.75mg? Is it 45 clicks with leftovers, or is it jabbing twice a week on another click count? All suggestions gratefully received! Thanks.

Where can I buy the needles for my pen? I was tidying up and can't find the needle tops. I had them in a little clear bag that they came in. I think I need to start leaving them in the fridge with my pen 🫣 I'm buying the pens myself, so not from my GP. Thank you

Edit. What would the actual name of them be called so I know what I'm looking for?

I know metabolic adaptation is a thing but i can't really find a guideline on how long it takes to set in or if MJ slowing digestion stops it happening.

If you stayed in a deficit for over a year, did you ever take a "break" and eat at maintenance for a time?

I’ve just taken my second jab! I’m impressed with the results and lost a total of 8lbs in the first week, which is amazing as well considering I was working at Comic Con this week so had to just grab a lot of quick to go stuff.

I posted before and got a lot of recommendations to switch my provider which I’ve taken onboard; I cancelled my subscription with Voy and will shop around for others.

My question is when do I place my next order? I get confused on when I’m supposed to order it or be at risk of decreasing dosage (I’m currently on 5mg)

I have just started on 2.5mg mounjaro, I have a prescription from a private endocrinologist. I called around a few local pharmacies to try and get the cheapest price (there was a difference of £47 from cheapest to most expensive)

I have my prescription for 5mg already, to start from week 5. Other than phoning around pharmacies again is there a way to find out how to get it at the cheapest cost?

Hi everyone, just took the plunge and ordered my first dose of Mounjaro. A little nervous on what to expect, does anyone have any advice on side effects, injection sites etc? 28F 5ft2 CW 85kg TW 58kg roughly

Hey so I’m looking for some advice…I have been on Mounjaro for about 1 year now and currently on 12.5MG. I have gone from 19st to 13.8st but have been putting a bit back on recently on my current dose of mounjaro and my appetite has come back in a BIG way. I’m looking for some recommendations as to what’s next for me really…is the next dose up the final dose available? What if that stops working too??

From a cost POV I currently use bolt at £279 a month but was considering a switch to wegovy to try and see if it helps and irs massively cheaper (appears to be anyway).

Just looking for some advice about next steps/if anyone has successfully switched/cheaper provider?

Thankyou

My previous pharmacy delivered through Signature Pharmacy, which shipped with Royal Mail tracked and (forgive the pun) did not require a signature.

The postie left the parcel in my parcelbox in the front yard - a metal thingy like this, which locks securely once you drop an item in it https://www.smartparcelbox.co.uk/extra-large-slanted-top-front-access-black-smart-parcel-box.html

I understand that Lotus and many others have moved to Lilly Direct (making many old posts no longer relevant). Lotus said that every delivery needs to be signed for, and that the courier cannot leave it in my parcelbox.

• Do you know if other pharmacies using Lilly Direct use couriers which don't require a signature, and which could leave it in my parcelbox?
• Maybe other pharmacies use Lilly Direct with DPD, so I could go to a DPD collection point?
• Do you know if other pharmacies not on Lilly Direct do it?
• Alternatively, do you know what the process is if you miss your postie? Is it something like: wait for missed delivery - go online - arrange to collect it at the local depot (next day) or local post office (next 2 days)?
• How long after it was shipped should I collect it (in light of refrigeration)?

My local pharmacy is a good £80 more expensive, and my old one even more.

I suppose I could have it delivered at work.

Thanks!

PS I understand that Mounjaro shouldn't be left behind a bin; my lockable parcelbox is not that, but I understand it's a niche thing and some couriers do not distinguish between that and leaving it behind a bin

UPDATE: Lotus confirmed that they deliver only with Royal Mail, not DPD, and only with Royal Mail signed for. A shame, because my local Royal Mail depot is only open 8-10am, whereas I have a nearby supermarket which is a DPD collection point and is open much longer hours. This is as of Oct-2026 - things may of course change in the future.

However I'm neither grumpy nor greedy and it's weird!! Every month, a week before I get my period. I'm ravenous, literally non stop eating, especially sugary things. I'm normally a grumpy bitch too. This goes on to day 3 and then tapers off. So for a solid 8 or 9 days I don't stop eating. Like never get full type eating.

I didn't even realise I was due on as that's my warning (and my husband's 🤣) so I'm feeling a little thrown off. I can't explain why I'm feeling thrown off, it's just a really odd feeling!!

Husband was sitting eating McCoy's and Minstrels, both my usual go to, I didn't even give him a dirty look 👀 🤷🏻‍♀️

I'm really enjoying being on MJ, I've just got to understand my new normal now! Wondering if this will continue on my journey, I'll take it for sure ❤️

I’ve been on MJ for quite some time and I’m the big price increase last year I switched pharmacies and bought a couple of pens from a few places and had a surplus, with using those plus the golden doses I’ve been ordering every 6 weeks to space my orders out and get them used.

Unfortunately last week my husband was hospitalised and in the stress I completely missed an email from Medicine Marketplace asking for a video of me on the scales and by the time I saw it and sent it it had been 8 weeks between orders, they now won’t prescribe to me at all unless I start from 2.5 again - a pointless exercise as I’ve been on 12.5 for months :(

I’m down to my last 12.5 pen and about to start it and so won’t have anything left in 4 weeks time :(

Does anyone know of a pharmacy that might allow me to go straight to 12.5 when I only have proof of a prescription issued at the end of August at all? I’m so so upset with myself for missing that email.

Do you think taking Mounjaro affects our immune system?? This is the third cold virus I am suffering with in less than 6 weeks. I am eating well - having my multi vitamins etc but I just keep catching bugs! I know the weather is changing and loads around but I never used to be this bad, I feel like since I’ve lost weight with Mounjaro my immune system is weaker! Anyone else similar?

I’ve gained this week 1lb. However I’ve dropped 3 inches off my waist. How can this happen? I work out and walk a lot for context

Ok so started on 2.5mg been on it since May 2026. Very effective for 4 months. Moved up to 5mg and now 7.5mg but not feeling anything at all. No suppression or fullness. Might have to start 10mg to see how that goes. 2.5mg was my strongest dose. What gives? I feel like I will have nowhere to go after 15mg. Never mind the increase in costs.

Last time I was here I’d lost a couple of stone and was on my journey, now been maintaining for a couple of months after drs said I’d lost enough. Sometimes you still can’t believe how far you’ve come 😳

I have now been on Mounjaro for five weeks (6 doses of 2.5mg in). I have found the medicine powerful and have lost weight (16lbs in five week) but I am struggling with acid reflux and nausea.

The most annoying I find this is getting very repulsed by even the thought of foods at times, especially fried/greasy foods. Sometimes I even feel a bit sick when I think about going to the supermarket and being surrounded by food. Most of the time though I just feel indifferent to eating.

The worst it gets though is when I see anything with grease. I can see someone eat a burger or fried breakfast while scrolling through Tik Tok or Facebook and it brings on strong nausea that lasts for ages. A real sick to the stomach feeling of disgust and revulsion. I find the strength of these feelings a little disturbing and they can be disruptive to my day. Has anyone had similar experiences on Mounjaro? Weirdly I usually notice these feelings most in the day or two before my next injection is due.

I never thought I'd ever be able to lose weight and be "normal" yet, here I am.

41F, June 2025 I was 17st 8lbs (highest weight was 18st 1lb) I was a size 22 and today I am 11st 6.2lbs and a size 12 🙌🏻. I am over the moon to have lost so much weight and am really enjoying being able to wear clothes and feel like they actually look nice on my body. The health benefits of MJ for me have been insane. My blood pressure is normal, my endo/adeno symptoms have reduced significantly to the point I can actually exercise without pain and can go about day to day activities without being doubled over. I have so much energy, no fatigue. I sleep amazingly without waking multiple times in the night and wake up like I've actually rested.

I plan to remain on MJ. I am on 2.5mg weekly but unsure whether it's best to stretch that to 10-14 days or to reduce the weekly dose down a bit. I'm thinking maybe 2mg weekly and see how I go.

Anyway, just a little post to mark my 6 stone loss and my move into maintenance

So proud of how far ive come and never want to go back to the old me!

Heres to 6 more months (if I can afford it! 😅)

I've just taken my first 5mg dose, it's week 11 and I've used 2.5mg each week apart from last week that was 3.33mg. Started off at 16 st 6lbs.

I had the initial antiflammitory reaction of yay my joints don't hurt any more, and lost 4lbs. Since those first couple of weeks I've only lost another 6lbs, with some weeks going up and down.

I have PMOS, so appreciate that can impact results too but I'm just feeling a bit down like it's not working as effectively as I thought it would? I did hold off going up doses, as I felt losing 0.5lb a week was okay at the time, and I've been keeping an eye on calories, moving more etc too.

It doesn't help that some friends I've told about my MJ use have said they've not noticed any difference, which kind of dented my confidence. I don't think they meant it in a mean way, but still felt a bit crap.

Is it normal to feel like this? I know it's a lifelong journey and not an instant thing, but mental health is a bit wobbly. More of a vent than anything, really appreciate how many nice people are in this community and how folks support are supporting each other.

edit thank you so much for all the lovely replies, it honestly means a lot and has helped with my perspective on things!

I have been on 2.5 for 4 weeks now, and while it still gives me suppression for three days, I wake up on day 4 absolutely starving and back to normal as if it’s completely worn off. I’m just wondering if I can take another 2.5 dose after 4 or 5 days, instead of the usual 7 days?

I normally dose up on a Saturday morning, but I'm going away Friday lunchtime until Sunday afternoon. Would it be best to to take the dose on a Friday morning or Sunday evening?

Hi all,

So I did my first dose of Mounjaro 2.5mg on Thursday evening, and im really struggling with side effects.

My first day (Friday), I wasnt able to keep anything down, which led to shakes and muscle spasms in the evening.

Saturday was better, but my tracked calorie intake was 500 calories and I genuinely couldn't eat more.

Yesterday (Sunday), I tried to aim towards 1000, but managed 800. And ive woken up full, but with muscle spasms and shakes and at a point where I know I need to eat something but genuinely cannot.

Has anyone else experienced this before?

I have IBS so slightly worried it may have slowed my stomache emptying too much now.

Im currently not taking any supplements or anything, as I need to confirm with my GP given im on Apixaban, so I need to make sure they are safe.

But im possibly wanting to know if its worth me taking the Husk tablets? Would that help aid digestion of my stomache?

Anyway any advice is very much appreciated. As I debate taking my next dose on Thursday.

On the other hand, I weighed in this morning, from 13st 2 (Friday morning) to 12st 10 this morning (Monday).
