NEXTGEN GROUP B.V.(The Netherlands) Reviews 

I ordered the peptides quite easy on line what seem to be a trust worth website.
Spending a total of 250CHF. when they were held up in customs and then returned to Nextgen they was no contact despite mailing many times and no refund given.

I ordered 3 times from NGpeptides. I got a discount code and ordered another batch of retatrutide. After I payed for it, I realized I wanted another ghk-cu pen but wanted to avoid extra shipping and still profit from the discount code.
I messaged the company and almost immediately got an answer. Things got sorted the same day.
They are super helpful and fair!
Definetely recommend.

The retatrutide is doing it's work. Allready lost 7 kg! ☺️

Product came quick but the Reta wasn’t working at all on my lab rats, 4 weeks of intensive test noting happened. Support isn’t taking you seriously. Not recommended.

I've ordered twice now, purchasing two reta pens each time, and both experiences have been great! The delivery was fast on both occasions, and the overall service has been excellent.

The only improvement I'd suggest is the pricing structure. For example, buying three 10 mg pens costs €296.97, while one 30 mg pen costs €239.95. I think the pricing could be structured more consistently so customers can easily compare the options and get better value when buying larger quantities. At the moment, some of the combinations feel a bit unintuitive.

Other than that, I've had a really positive experience with both orders and would happily order again!

They care of the well-being of the people. Do your personal research and try this product. It works.

Ordered Bpc 157/tb 500. Started using about 4 days ago. My appetite is nonexistent. I am not a person that needs to lose weight and normally eat 5-6 times a day. I fear I may have been sold a glp-1 that was mislabeled. I have used bpc157/tb-500 before from another site and did not experience this. I have a shoulder injury and was hoping this would help but not being able to eat more that a couple bites of food a day for the last few days isn’t helping.

I am in Italy.
The first reason why I ordered from him is because he answered to my questions before placing the order.
However, I placed the order and paid in the morning and in the afternoon my envelope was already at the post office and I received a mail with tracking. He also answered to my questions when I received the pen.
Expectations exceeded I can say.

Fast service
Pure peptides
Great prices
I switched from my last company and won’t be looking back

False advertising. The GHK CU has no full ingredients on the website and on the packaging it’s very diluted with multiple ingredients. It also does not state that it comes from China - had I known this I wouldn’t have bought it. I am waiting for a refund but no reply!

Updated review ;

They are accusing me of leaving 2 reviews as if it’s done by the same person. The order was meant for 3 people the third person hasn’t added their review yet but it’s coming.

They never acknowledged the fact that the order was delivered wrong in the first place because of THEIR mistake. It was ignorant of us to travel with the package unopened it being the summer and leaving it in the fridge. We left it like that till we were ready to use it. Everything has an explanation however they never offered any time for any dialogue. Their immediate reaction was accusation and their comment proves their unprofessional tactics. Disgraceful.

We have receipts bring it on!
—————————————-
They deserve zero stars. The customer service was hostile and completely unprofessional. I was not treated like a customer at all.

I was accused of being a scammer simply for trying to resolve an order that they had mixed up. Because I was outside their strict two-day limit, they refused to even have a professional conversation with me about the issue. Instead, they left my messages on read and provided no meaningful assistance.

I was essentially left out of pocket for an order worth around €700. The way this situation was handled was extremely disappointing and unacceptable. I would strongly advise others to think twice before ordering from this company.

They sent me the wrong order and blamed me for not contacting them within 2 days. Horrible customer service. Never experienced anything like this a specially since I spent over 600 euro’s. Wont be ordering again nor will I recommend anyone to order from there.

Your reply shows the lack of professionalism you have. First of all this was mineband my sister’s experience. Since you do not ship to the country where I’m staying, I had to order to my sister who was planning to visit me. We have both tried to contact you about this. Me over email and my sister over whatsapp. Your reply was disgusting. We both spent money on your products. And we are both repulsed by your replies by immediately doubting us and treating us like criminals. I’m glad you are at least acknowledging that we have placed an order with you( multiple orders btw). My sister brought the product with only checking the amount of vials. Instead of you admitting to your mistakes by sending me the wrong order you have treated us like criminals even after providing you with proof. Anybody who plans to place an order with you should know how they will be treated after the order has already been placed. They should also know your “2 day policy”. Can’t believe a business running like this with horrible customer service and attitude. What a disgrace.

Complaint about my order

I placed an order on Friday, and so far I have not received any email with the tracking number or any update regarding my order.

I have already tried contacting the company via WhatsApp and email, but I have received no response. They simply do not reply, do not get back to me, and provide no information about my order.

This is very disappointing and unprofessional customer service. I would like an update on my order and my tracking number as soon as possible.

good and quick delivery, excellent customer service. very good quality of the products.

delivery in less than 24h.
impressive

I received the package. Everything is ok. The mixture came out very well. Thank you very much. I will order again when I need it.

I had a really good experience with Nextgenpeptides. I ordered 2 bottles, but due to low stock they could only ship one first. They kept me updated the whole time and were very responsive on WhatsApp, which I really appreciated.

When the second shipment was ready, they even included an extra bottle as compensation for the delay. Super kind, thoughtful, and genuinely a trustworthy seller. Highly recommended.

Disrespectful attitude, ineffective product.

Also, the Kvk entry for the company is something you should see yourself: This is a dodgy provider.

Edit: Fake review huh? Here is the Kvk extract for this company

TA gevelreinings- en klussenbedrijf
Gevelreiniging, tevens klussenbedrijf. Detailhandel via internet in laboratoriumbenodigdheden en onderzoek substanties voor educatieve en onderzoeksdoeleinden en tevens importeren en exporteren van deze producten.

In the queen's English:

Facade cleaning, also a handyman business. Online retail of laboratory supplies and research substances for educational and research purposes, as well as importing and exporting these products.

Do you also happen to be a lawyer?

Guys, don't bother with this person/"company", he cannot even provide a COA for different batches. You have no idea what you're buying and if you read the rest of the reviews (REALLY read them, not just the ones from dodgy profiles with 2 word reviews) you will see someone pretending to be doing something that is completely out of their depth.

Buddy just stick to facade cleaning, you are much better suited. The world needs more of that, than dodgy medication providers with poor customer communication skills.

On 9 July 2026, I placed an order for three products through NextGenPeptides.nl. At the time of ordering, none of the products were marked as out of stock during the ordering process as per the sites refund policy.

On 10 July, I received an email confirming that my order had been dispatched with no mention of products being out of stock as indicated would be the case by the refund policy that states "You can see when a product is on backorder during the ordering process. This information is also included in the confirmation email you receive from us."

Later that same day, the package arrived, but it was missing one of the products that I had already paid for.

Only after I contacted customer support via WhatsApp was I informed that they did not have stock of the missing item and might receive it the following week.

At no stage before dispatch was I informed that they were out of stock. There was:

No indication on the website that the item was unavailable.
No email advising me of the stock issue.
No opportunity to choose whether to wait or receive a refund before they shipped an incomplete order.

As I was due to leave The Netherlands I would not be available to receive a delayed shipment, I requested a refund for the missing item. Support asked me to send a payment request, which I did immediately using a Wise payment link.

Since this all occurred on Friday, 10 July, I reasonably expected the refund to be processed by Monday, 13 July.

When no refund had been received, I contacted support again and was told:

"This is in progress but we dont have a Wise account."

I contacted my bank, who confirmed that the refund could still be processed by simply following the payment request link, regardless of which bank the merchant uses. I forwarded these instructions to NextGenPeptides.nl and received the response:

"Ok will check"

My bank then advised me to request a specific refund deadline from the merchant before opening a formal dispute. I requested that the refund be processed by 17:30 on 13 July 2026.

The only response I received was:

"Oke!"

As of 19 July 2026, I have:

Still not received a refund.
Received no further communication or updates.

Based on my experience, I cannot recommend doing business with this company. Accepting payment for products that are unavailable, shipping an incomplete order without informing the customer, and then failing to process a requested refund within a reasonable time demonstrates very poor customer service and business practices.

I have retained the order confirmation, WhatsApp conversations, payment request, and correspondence as required by my bank, and can be made available to Trustpilot, and being provided to the relevant consumer protection authorities which I am currently dealing with.

After receiving the incomplete order I noticed that the contents for two different items had the same batch numbers.
When compared to an order a friend received for completely different products, they too had identical batch numbers to mine, which raises more questions about the products supplied.

I hope this review helps other consumers make an informed decision before purchasing from this merchant.

They where really helpfull. I ordered 2 from them and they send it really fast. It makes the food noise less active. Sometimes it doesnt work as good as the other time, but i think that that are because off the hormones that the female body produces

Superb quality of products and excellent after sell attention
