Amazing! The support network, advice and admin, especially Sophie, I cannot fault it at all! I’m a Convert

I’m writing this review because most of them are saying they didn’t receive their orders. The ones that haven’t received them are or have been tricked into purchasing from a fake Alluvi vendor. The only real websites are-Alluvi.shop and Alluvi.bz. Sophie and Jeremy are super helpful and fast at replying. I’ve ordered plenty of times and always came the next day via tracked Royal Mail. Lost 15KG is 4 weeks, their product and company are the real deal!

Thank you Alluvi+especially Sophie for a great ordering and helpful experience. I was scammed on tiktok pretending to be Alluvi lost 300£ So be aware.
Julie Williams –
Ordered and received within 48 hours – PLEASE WATCH OUT FOR OTHERS PRETENDING TO BE THIS ONE. The scammer usually sits on the Alluvi TT page and messages people who comment giving a number to message.. I received said message but had already ordered off the genuine sellerTHANKFULLY. Alluvi.org will not ask you to bank transfer nor watsapp!
Fabulous experience with them and absolutely recommend!

I was a bit hesitant to try Reta products at first, but I’m so glad I did. They’ve been genuinely effective and made a real difference for me.
Ashley Lusted –
Remember to be careful when seeing the brand being advertised over social media there are a lot of scammers.
Use the official web pages .shop or .bz
I ordered mine 11am Thursday and it arrived 11am on the Friday. Got 2x packs of goods and got 2x water bottles.
Great service

Alluvi is a brand that genuinely cares, and you can feel that in everything they do. The products are not only high quality but they actually work—I’ve regained my confidence and I’m so close to reaching my goal weight. What stands out most is the heart behind the brand; they don’t just sell, they support. Delivery was smooth, packaging thoughtful, and the whole experience left me feeling looked after.

Le laboratoire ALLUVI est le seul fournisseur de retatrutide ALLUVI les autres sont des faux sites ils arnaquent une fois débité c’est fichu. Ça vaut le coup c’est en Angleterre et ils vendent aux français. Par contre attention frais de douane à payer + taxes de conversion la facture grimpe
Très satisfait du déplacement je pense que bientôt les français ne pourront plus l’acheter

Jess Mitchelle –
I actually purchased the wrong pen by accident and was worried about returning it and getting the right one. I genuinely thought I was stuck. The girl i ended up dealing with, Sophie, was amazing. Helped calm my fears, told me where to return the item and before they even revieved the return ….not only did they send what I need….it came next day. Blown away!!! Not had a level of customer service like this , well ever !
G.P –
Ordered multiple times. Always very friendly and efficient.

I’ll be honest—I was VERY skeptical about Alluvi Health Care at first. I had read so many horror stories online about shady clinics, poor communication, and empty promises. I half expected this to be the same. Do not trust half of TikToks. There’s only 2 x sites : Alluvi.Biz and Alluvi.Store. Do not go to others or even the google page. It’s an impersonation and fake. Join the Telegram group too! Really important.
From the very beginning, their service was next-level. They were clear, responsive, and didn’t treat me like just another number. I decided to trust the process, even though I was nervous, and I’m genuinely glad I did.
Not only did they deliver Reta pens exactly as promised, but they also provided safe and reliable alternatives to MJ like Tirz that I wasn’t sure I’d even be able to access. The entire process felt professional and surprisingly seamless—nothing sketchy, nothing hidden.
Honestly, I’m still shocked at how smooth and trustworthy the experience has been. What started out as hesitation has turned into confidence—I’d recommend Alluvi Health Care to anyone who’s skeptical but curious.
If you’re on the fence, I get it—I was too. But based on my experience, they actually deliver what they say.

Fantastic service and fantastic product ( Retatrutide ) for me I feel so lucky to have found this company and product with a special thanks to the lovely Lisa H on introducing me to it. Grateful customer here 🙏🏼
Claire Villette –
Wow alluvi you never cease to amaze me… ordered yesterday at 1.57pm and order arrived at 10.03am this morning. Amazing service as always, receipt sent to me straight after ordering, then not even an hour later confirmation that my order was being processed, then a message from Sophie with my tracking number, 3 hours later an email from Royal Mail giving me delivery date and time frame. Thank you so much as always Sophie, I will be ordering again very soon and the free bottle a lovely touch (Im now the proud owner of 2) x
Nathan Hall –
Iv had 2 deliveries so far both came next day and also the results are starting to show already love alluvi. 5 stars from me
Mark Hooper –
I was nervous when ordering as there was no customer service number, hard to find an email address or physical address… that said, I ordered from them, the product took five days to come, I did email customer service and they did get back to me when they could. I understand they are a busy company so be patient, they will get back to you, wou will get your order. Thank you guys!!
Erika Armitage –
