Total Scam. I’ve used many Weight loss ‘fads’ they all work, except for this one. Tried a 3 month bundle, using Waterout, ApidoBurn, FatBurn and Nightburn, followed all instructions to the letter.... See more

Delivery states 3-5 days but it's more like 7-10 and 2 different couriers are used. The quantity in a box is lacking, lucky if it covers a week supply but website claims to give products 12 week to work, just a ploy to get people to spend more money and order frequently

Total Scam.
I’ve used many Weight loss ‘fads’ they all work, except for this one. Tried a 3 month bundle, using Waterout, ApidoBurn, FatBurn and Nightburn, followed all instructions to the letter. Nothing happened whatsoever! It’s essentially powdered cordial, total waste of time. Don’t buy into this con, there are many others which actually work… keep looking and avoid SlimJoy! #slimSad

On my third day now
On my third day now, noticed definition in my stomach just after 2 days feel less bloated and look slimmer also I'm sleeping really well and normally I don't
Does not work
Does not work. Should have known better than waste my money on a lack reputed UK medical testing. Hope other won’t waste their money.
Good products
I have ordered these products twice now and the delivery has been really quick (3-4 days) products exactly as described. I received a £10 discount for my next order too. I know other people that purchase the products regularly without any issues as well so these are definitely not a scam as some reviews say. They seem to be speeding up the weight loss slightly more than just calorie counting but I don’t think they would work if you didn’t change your regular eating habits….
I wish I had read this before ordering
I wish I had read this before ordering
Having taken the money from my account I receive a poorly translated email stating unexpectedly out of stock!
Will wait for the refund but something tells me I have just been scammed….shall update if I am proven wrong
Dont waste your money
I have purchased many items from slimjoy...tbh nothing works. The Adipoburn XXL are only water tablets, i have had to stop taking them. No sleep with going to the toilet all night.
Will not be wasting my money on anymore slimjoy products.
No way to email or anything as nobody…
No way to email or anything as nobody gets back to you at all!
I thought you got a reminder before money went out! Yet nothing money just went I have cancelled the subscription as I never get replies either. Disgusting customer service. And I best be able to send the products back!
I havnt yet tried the products as I wanted to know if it was safe to use more than 1 product at a time but again no reply
i have sent so many emails to customer…
i have sent so many emails to customer support to cancel my subscription, I received another packed when I didn't want it and I haven't received an email from them yet
Interaction with Blood Thinners?
I have not had any trouble with the medication or the delivery - took the first pill this afternoon and feel a little acid in my stomach but consider this is not anything to be alarmed about. What I am concerned about is something more serious: I am taking blood thinners and have read that one of the main constituents of Adipoburn XXL, Green Tea Leaf extract, is incompatible with blood thinners as it contains high levels of Vitamin K. I cannot find any evidence from trials conducted by Sensilabs ( all they seem to want is to sell you more slimming products ) which is a pity. Having an IRN check tomorrow and if Adipoburn is affecting coagulation I will report it in another post. Would be interesting to know if other users are similarly affected.
Positive experience so far
I too have order twice from slim joy before reading the reviews and both deliveries arrived within the week. I have also seen results with consistent weight loss of an average of pound a week along with healthy eating and exercise. xxl night burn and adipo slim extreme. I will be ordering more this week. Considering the subscription option but reviews are not great if you want to cancel any positive feedback on subscriptions out there?
I cancelled my monthly subscription in…
I cancelled my monthly subscription in March as I didn't see any difference since using the product. I have continued to receive emails from Kalma to pay for the product. It is appalling that I am expected to pay for a product despite not receiving it.

Order not received in 3 weeks
Made an order since the 15/08, haven't seen any item yet, mailed them after 15 working days, no response, no number to contact them, hope I've not been scammed by slimjoy. Wished I went through reviews before ordering, I just need a refund not a hot cappuccino like some comments reads. Just need a refund, have bought other products, it came so quick.

Ordered 60 euro worth of products just started them today, within 5 minutes I've started to feel voilently sick and dizzy, I've been lying down since, not ever again going to go near them, what a waste of money, whatever is in these can't be good for you to be feeling this sick after them, I've contacted them by email, not surprised if I don't get a reply from them after reading these reviews! Shocking

Capsules doesn't work
I've ordered a lot of products of this company. One of them was subscription, but when I've took first pack I understood its nothing , it's doesn't work -AdipoBurn XXL double action, I've canceled my subscription, but nobody care...they continued to send me and nobody unswerving on my emails.But I am not pay anymore none, I've try to contact with them, nobody answered.
Only one thing is good, I like
L-carnitine 1000 pure or FutBurn 2000.
L-carnitine always good.
The capsules I see no results.

Really happy after feeling dubious
I like some others bought my first batch before reading these reviews and after reading them thought "oh no what have I done" but I am glad that I did so I thought I would write this review to put some people's mind at ease. First order received on time (water out, fat burn and nightburn) and me and my partner started straight away full of optimism. All I can say is that they taste pleasant enough (just like weak juice, nothing horrible) and we both started to see results within the first week. (My partner excercised - I didn't but I could still see a difference in my shape!) We only got enough for 2 weeks at first but then decided to order a months worth each. 2nd order arrived within 4 days, excellent. We have now finished our first 2 weeks and are a week into our month programme (water out, fat burn, night burn and Adipoburn) can still see results everyday, plus it keeps us focused on trying to eat healthier. Would definitely recommend and when this last batch starts running low will definitely be ordering again. Hope this helps!

I’m 2 months into a 3 month program and it’s working well down from 32” waist size 14 to 27” waist size 8-10. I’ve been exercising daily and eaten at the times suggested in the leaflet (not after 6pm. The water out only works if you take it for consecutive days, and is best used after the fat burn sachets have ended.
You do NOT get your money back…
I have tried several of their products and none work. I have submitted my guarantee money back form for my latedt purchase and still heard nothing. It is a con. I has been weeks now and i have sent several emails. Time to get in touch with the ombudsman🤨
