Pleasantly Surprised
Straightforward ordering process. Good app to monitor order progress. Kept informed. Quick approval. Delivery slightly longer than expected. Very well packaged pen. Slight negatives were only 4 needles and no sterile wipes in my package! But generally very happy, and would re-order again if the price were right!

Dear Angus,
Thank you for taking the time to leave such a detailed review — it’s great to hear that the ordering process felt smooth, the app kept you well informed, and that approval was quick. I’m also glad the pen arrived well packaged, even if the delivery took a little longer than expected.
I appreciate you highlighting the missing wipes and the limited number of needles. That’s genuinely useful feedback, and I’ll make sure it’s passed on so we can tighten things up for future orders.
It’s great to hear you’d consider re‑ordering, and we’ll keep working to make sure the experience — and the value — stays right for you.
Kind regards

Hey Dominica,
I apologise that you couldn't get through to our team immediately; we were experiencing a very high volume of calls at that time and got back to you as soon as possible.
Regarding your replacement order, it was shipped later that day after we were contacted about the missing parcel. Please let us know if there’s anything else we can assist with.
Best wishes,
Justin
Really poor service and communication
Really poor service and communication. Promised dispatch was not sent on time and getting in touch with the company was near impossible. Tried online support and despite being 2nd in the queue was given a wait time of between 2-5 hours for response. Tried telephone support and after a few mins call was disconnected. Your money has been taken but have no idea when your items will arrive. If you want to make sure you don't miss your medication try using another more efficient and communicative pharmacy as it could have a negative impact on your treatment. The service got worse - wrong medication was prescribed and despite a promised 14-20 mins wait for assistance, 45 mins later no response.

Dear Customer,
I am incredibly sorry to read this review. While I sincerely apologize for the delays in dispatch and the difficulties you faced reaching our support team, I am most concerned by your mention that the wrong medication was prescribed.
We treat any report of a dispensing or prescribing error as a critical incident.
Because this is a public review, I cannot see your order details to investigate this immediately. Please email us directly at support@heyslim.co.uk so I can personally look into this.
I look forward to hearing from you so we can put this right.
Kind regards,
Justin
So this company took money from my…
So this company took money from my credit card on the 22nd of December before the consultation had already even been approved. They then had the 22nd 23rd and 24th to send the medication out and they didn’t. They said that the consult hadn’t been processed they then said that the pharmacy was shut. The 27th was also a working day. They never sent it out then when it did finally arrive for the following week it was absolutely saturated all the packaging trampled and torn . There was no introduction letter with contact. If I had any problems there was no other tablets in the pack such as cyclizine which other providers have offered I found the company very awkward to deal with. They were quite happy to take my money, but not as happy to send the medication out I will not be using them again.

Dear Paris,
I am sorry to hear about the condition your package arrived in and your frustration regarding the delays over the Christmas period. I would like to address your points individually to provide clarity.
1. The damaged package: It is unacceptable that your medication arrived saturated and crushed. Whether this was due to the courier or the weather, you should never have to accept damaged goods. Unfortunately, since this parcel was picked up from a collection point, we don’t have visibility on the condition of the parcel in this case.
2. The delay (Dec 22nd - 27th): We apologise that we could not dispatch this before Christmas. As there was a change of address, our support team needed to adjust this before shipping, and during the peak holiday volume, this took longer than usual. We also closed for the bank holidays to give our clinical team a break. We are sorry this wasn't communicated clearly enough to you at the time.
4. Missing anti-sickness meds: Unlike some providers, we do not automatically bundle additional drugs like Cyclizine with orders. As a responsible pharmacy, we only provide ancillary medications if a patient specifically requests them and our clinicians deem them necessary for that specific individual.
We would like to resolve the issue of the damaged delivery for you. Please contact our support team so we can make this right.
Best,
Justin

Amazing service
Amazing service ! The best I’ve had on my journey . Obviously we all switch to get the cheapest offers and this company did not disappoint ! £58 off a 15mg pen was great but, then even better the service - easy, no fuss uploads , 1 full body picture , selfie and the dreaded full frontal body shot ( mine I was thrilled for the first time , 4 stone down !) . Within 3 days ( and over the New Year’s Day ) delivered to my door . Better than my 4 previous suppliers ASDA , IQ DR, BOLT and Pharmacy2U ( just will mention no issues with others but, different experiences ) . If you are thinking of using this company no doubt do it . I’m hoping some offers drop in my emails as would continue to use but, needs must on cost ! Good Luck !

Dear Karen,
Thank you for taking the time to share such a detailed review — it’s brilliant to hear how positive your experience has been.
It’s great that the process felt easy, the uploads were straightforward, and that your order still arrived quickly even over the New Year period. A huge congratulations as well on being 4 stone down — that’s an incredible achievement and you should be really proud of that full‑body photo moment.
I’m also glad the pricing and service compared well with your previous suppliers. We appreciate the honesty around cost too — completely understand that it has to make sense financially, and we’ll keep working to offer good value.
Thank you again for the recommendation and for trusting us on your journey.
Kind regards

constantly chasing now I've given up!
constantly chasing now I've given up!
I signed up and needed to get a verification code via text this was not sent. So I reached out to heyslim, had no reply, so I chased up.
They said it was working? tried again, no luck.
Reached out again, no reply......... chased again.
3 days I have tried to place an order the customer service is awful.
Had enough moved onto another supplier, not chasing anymore. This was a online chat which stated the wait time was 1-3 mins and there was only one person in front of me? But yet the next day still no reply?!

Dear Suzanne,
It’s clear how frustrating that experience must have been, especially when you were simply trying to get started and couldn’t progress because the verification code never arrived. Having to chase repeatedly, with long gaps in communication, isn’t acceptable and doesn’t reflect the standard we aim to maintain.
Your comments highlight an area where our responsiveness should have been much better, and I’m sorry you were left feeling unsupported at the time.
Kind regards
Ashis
Smooth first experience
I don’t usually write reviews, however I felt I should share my experience with Hey Slim. I placed my first order on Thursday evening around 11pm and, after placing it, I made the mistake of reading some reviews on here which left me feeling a little worried.
That said, my experience couldn’t have been better. Within a few hours my prescription for MJ was approved, and the medication was delivered in under 48 hours. The whole process was really easy, straightforward, and well communicated throughout.
Overall, I can’t fault the service.

Unprompted review
Perfect, highly recommend!
After reading some of the negative reviews on here I was quite appreciative of placing an order for mounjaro. I’ve been on the medication for a year now and after the price hikes, I’ve swapped suppliers a few times. I cannot praise hey slim enough, fast processing, regular updates on the status of my order. From placing my order to my mediation getting delivered, it was less than 48 hours. Please give this company a chance, they have been fantastic.

Unprompted review
Regarding my Order #3584
Regarding my Order #3584, I purchased Mounjaro 2.5 mg. After receiving the dispatch email, I never received the parcel, even though the tracking system shows it as delivered.
I reported this issue to customer service, but many days have passed without any resolution. No one has arranged a redelivery or provided a clear solution.
The time when I am supposed to start using the medication is getting closer, and this situation is extremely irresponsible.
