The best company and source out there…
The best company and source out there with the best customer service. I received multiple orders with no issue. There is a wait, they are very transparent with the process. Overall, I recommend this company and will be purchasing more in the future.
Unbeatable prices and quality
I hardly give reviews but this company has been amazing. The selection of items available for purchase are extensive and the prices are unbeatable. The customer service is outstanding. I had a problem with a purchase and they are taking care of it for me ASAP. I have made 3 purchases so far and every single one of them have been smooth and super easy. The community within GBK is unlike anything I have ever been a part of. There is not another company in this field that I would trust as much as GBK. Good products, awesome customer support, on time shipments with tracking, a great community, and an ever expanding product selection. What more could you want?
Always an excellent experience with GBK…
Always an excellent experience with GBK the community of researchers is unmatched and the platform is custom built from the ground up. Multiple payment options available. I would definitely recommend. Prices are very reasonable and they allow you access to a large selection.
The only way to go dark grey…
This is the only “over the pond” source I trust. No sketchy payment methods/whatsapp/telegram groups. One of the most well developed websites/platforms I have ever encountered. Built in 8x testing. Trusted vendors that do in house testing before shipping and have never had a product fail a single third party test. Competitive pricing. If you want to pay dirt cheap elsewhere and risk being scammed, getting fake product, or coming out of pocket hundreds more dollars to third party test yourself, be my guest. If you want quality, consistency, reliability and buyers assurance, go with GBK. Yes, shipping does take forever. But they are very upfront and transparent about shipping times, it’s all over the site and they make you take a module reiterating this before joining. The people who who complain about this are idiots because why would you purchase knowing shipping takes x amount of time, then complain when your order hasn’t shipped yet and it’s still well within the timeframe they give you?
Love this place
Love this place. A great place to be . Thankyou GBK
GBK is phenomenal!
I’ve been searching high and low for a provider with excellent testing and wholesale pricing. GBK is a great service and well run. Everything is explained and disclosed in detail. We have made several orders and are very happy with the product, I have also referred friends who are also enjoying the membership and repeat buyers.
Great company
I couldn’t be happier with this company! They offer great products with excellent quality, and their customer service is truly outstanding. It’s clear that they genuinely care about their customers and go above and beyond to make sure everything is taken care of.
From the quality of the products to the attention to customer satisfaction, they have exceeded my expectations. You can tell they are a company that stands behind what they offer and truly values their customers.
I highly recommend them to anyone looking for great products, great quality, and exceptional customer service. Five stars all the way!
GBK is home to 15000 Researchers
This is a safe resource for American researchers. I have made over 10 orders and received them all with not a single issue. Absolutely fantastic. Quality products 7x tested, prices and community are excellent
Great customer service
Great customer service, very transparent on how the platform is run. The pricing and product quality are second to none. Highly recommend GBK!
Excellent source of research materials
Excellent source of research materials, see some complaints listed and it seems there is a major comprehension deficit from those individuals, everything is laid out in black and white when you sign up regarding testing and the very few instances of a substitution. GBK is not a ship from stock source, they simply act as the go-between for overseas suppliers and end users. They do an excellent job at that! No complaints on my side, several buys in and everything delivered as promised!
Amazing community
I joined this community at the end of May and just read everything on the site and watched the chat. I ordered a sample in the shop first just to test the waters. I THEN ORDERED FROM THE GROUP BUY!. Its very clear how long it takes for product to be shipped and ive never had an issue receiving my product from my group buy or the shop! Im now 8 orders in and 4 group buys deep and very happy with the community and the people who run the site. Communication to me and trust is #1 and they have showed up :)
Best in the industry
Best in the industry! So
glad to have found GBK!
I’m so happy I found GBK been with then…
I’m so happy I found GBK been with then since almost the beginning. It has been a fun ride watching them grow into the largest platform in the space. It’s mind boggling how they have grown and adapted and crushed every challenge that has presented it self. Every day they make it better and better. Love the GBK family. I can’t wait to see what the next year and the year after bring. So grateful to be apart of this community.
Great products
Great products, awsome customer service.
Love this community

I've placed 2 orders so far
I've placed 2 orders so far! Easy to order, great pricing! The community is helpful and engaging. Thanks for a great experience!
Group buy kits
The community is so helpful in this space, research questions are so helpful. Orders are shipped out very effectively and on time. Great quality and grrat prices. I highly recommend G.B.K thank you for everything
GBK is amazing
GBK is amazing. If you want grey prices, products that are tested, a community that feels like family, the $10 a month is well worth it. Different payment options so you aren't messing around with something you don't know how to use. Very reliable with 13 orders in. May 29th my first order was placed. Come and be a part of the gbk family.
Absolutely Amazing
I have successfully ordered from here 4 times. Two group buys and two shop orders. I really appreciate how transparent the admin is, one of my orders was taking longer because of a chinese holiday so they shipped me a partial order at no extra cost. I especially appreciate the testing, they just upgraded to a 9 panel test and they test 7 vials of the same product. No one else does that. Also the benefits are fantastic, if you refer a few people then you get store credit and free months of membership. Ive been a loyal customer for 5 months now and will continue to shop only here.
The reviews from others that gave 1…
The reviews from others that gave 1 star are clearly bot reviews from people who were removed from the space. They dont accept BS and keep the community safe. Nothing else compares to GBK and nothing else ever will.
