Dear Joyce,
Thank you for sharing this — we really appreciate it.

Great initial prices but couldn’t maintain those prices so moved to a cheaper pharmacy.

Dear Brian,
Thank you for taking the time to share this. I’m really glad our initial pricing worked well for you, and I’m genuinely sorry we weren’t able to maintain those same rates long‑term. As a small independent service, our medication costs can fluctuate quite a bit depending on supplier pricing, and on this occasion we weren’t able to keep the original price point without compromising on quality or safety.
I completely understand your decision to move to a cheaper pharmacy, and I’m pleased you found an option that suits you. If circumstances change in the future or if you ever need support or advice, you’re always welcome to reach out — no obligation at all.
Thank you again for giving us a try and for the honest feedback; it genuinely helps us improve.
Kind regards,
Ashis
Impressed with HeySlim
I was really impressed with HeySlim as it was the only Pharmacy that actually gave me a personal Doctor that followed me on my progress. Dr Balan was so caring, answered questions very quickly and reassured me whenever I needed it. I discussed with him about maintenance and stopping the medication but he reassured me that I could always restart if I needed to. For the first time (I started on Mounjaro in January 2025, so have used quite a few different pharmacies) I felt I wasn’t just a customer and they only wanted my money but that they cared about you as a person and wanted you to succeed in reaching your goal. Ordering is easy and delivery very quick. Customer support is very good. I had to postpone delivery as I was away and that was no trouble at all. I know they are not the cheapest but sometimes it pays to pay the extra and know that they are there for you whenever you need them.

Dear Lulu,
Thank you so much for taking the time to share this — it genuinely means a great deal to us. One of the things we’ve worked hard to build into HeySlim is exactly what you described: proper continuity, real clinical follow‑up, and the feeling that you’re being looked after by an actual clinician who knows your journey, not just a rotating inbox of generic replies. Hearing that your experience with Dr. Balan made you feel supported, reassured, and treated as a person rather than a transaction is exactly the outcome we aim for.
We know there are cheaper providers out there, and we’re always transparent about that. But we’ve always believed that safe prescribing, quick access to a clinician, and genuine care throughout treatment matter just as much as the medication itself. Your feedback reinforces why we hold onto those standards.
It’s also great to hear that the practical side — ordering, delivery, and adjusting dispatch dates — worked smoothly for you. We want the whole process to feel easy and stress‑free, especially when life gets busy.
Thank you again for trusting us with your treatment and for recognising the effort that goes into providing a service that’s personal, safe, and supportive. Your words really do mean a lot to the whole team.
Kind regards,
Ashis

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

Awful, incompetent, threatening, leaking data, avoid
This company has been spamming me multiple times per day for weeks and won't do anything about it.
Their website doesn't work properly, they're impossible to deal with - I never did get my order. I've dealt with 10+ online pharmacies in the last year and they are by far the worst. I went somewhere else and got it all sorted in under an hour and considerably cheaper too.
Now struggling to get them to comply with GDPR.
Avoid at all costs!
Also be aware that they apparently have no issues with posting confidential information about your medical situation on here - most disgraceful thing I've ever witnessed. Had to make another complaint to get them to amend that. Received a threatening response from them suggesting I delete my review and then their breach of my confidential data won't show. Don't give these people any information you don't want shared with with world! Avoid, avoid, avoid

Dear Customer,
Thank you for your feedback. I have sent you a detailed email regarding this directly, but I want to address your concerns here as well to provide clarity.
Regarding the emails and your order: As a regulated pharmacy, we place patient safety above all else. The emails you received were not marketing spam; they were automated service prompts requiring you to upload clinical verification and medical history. We cannot legally or safely dispense prescription medication without verifying this information. Because these steps were not completed, the system sent reminders until the order was ultimately cancelled and fully refunded. We apologize if the frequency of these reminders felt excessive.
We have ensured you are unsubscribed from all non-essential communication.
Kind regards,
Justin

Royal Mail said delivered but no package. After being advised to contact the supplier can not get to talk to anyone left messages still no correspondence. Not happy with their customer service.

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
