Why are our prices significantly lower than those of SIGMA and other suppliers?

The reason we can offer chemicals at prices up to 90% lower than our competitors is multi-faceted and ultimately stems from our unique supply chain.

We serve as the 'buyer of last resort' for many businesses within the scientific community. This means that we frequently acquire complete inventories from businesses that are closing down, relocating, or being acquired by competitors.

We source our stock from various outlets, including other suppliers, universities, wholesale manufacturers, and often liquidated businesses worldwide.

Subsequently, we rigorously test and assay the acquired stock before making it available for sale from our warehouse and lab.

​

What about your range of ready to use formulations?

As we have grown and expanded into new sectors we have been releasing new products under our own brands such as the very popular Blue Boost range of Methylene Blue U.S.P. solutions! These formulations are made in our new (as of 2023 and upgraded 2025) state of the art production facility. This means that we have two labs on site, housed in separate buildings, one to process DTC products and one to process B2C products.

​

Our research and development, testing, production, packaging and QC  is all  done in the UK by our skilled technicians. 

​

Can you tell me more about your Blue Boost range of Methylene Blue products?

​

While we were the first company to develop Methylene Blue solutions for use as a research tool (Methylene Blue has been around for over a century - we just made it more accessible!), we are now being imitated by many other businesses!

 

Please be careful when choosing any ready to use formulations - most of our competitors are "kitchen table", operations and without the proper equipment and testing facilities only professional labs can provide. So while you may find cheaper Methylene Blue products elsewhere you will never find the same quality anywhere else! 

 

Blue Boost took 18 months to bring to market - firstly testing over 100 samples of raw Methylene Blue U.S.P. using both Mass Spec. and HPLC techniques before arranging a sufficient supply with our wholesalers.

 

We then spent 3 months learning how to refine the already USP graded material to remove any trace heavy metals or solvents.

 

Finally, we spent 6 months testing manufacturing techniques to ensure solution stability without the need for additives. Most of our competitors will use small amounts of Ethanol, Glycol or even some Hydroxides to stabilise their solutions! We have perfected a proprietary "Thermal Cycling", process which means we have nothing but Methylene Blue U.S.P. and Purified Water B.P. in all of our Blue Boost products!

 

You can only purchase official Blue Boost products through this website, our official ROK CHEM eBay store and from www.methyleneblueusp.co.uk.

 

Do you sell any other ready to use supplement's?

We sell a wide variety of pharmaceutical grade products that our customers use to make into supplement's for selling directly to their consumers. Currently we only sell our Blue Boost range but we have 8 products being developed in house which are at various stages of development.

 

We have 4 products in final testing including:

 

NAD + 

A Shilajit based product infused with Methylene Blue

Hydrogen + Alkaline water tablets

Colloidal Silver and Gold infused salts

Are your chemicals and consumables certified, tested, or assayed?

All our chemicals are either tested in-house using a variety of techniques or sent to our assay partners when necessary. Certificates of analysis can be provided upon request.

Our consumables stock is covered by the original manufacturer's guarantees, and we inspect the goods upon delivery to ensure they are in-date, undamaged, and, when necessary, sterile.

​

What is our returns policy?

We offer a 30-day return period for unopened items (chemicals and consumables) with no questions asked. For opened items (for example, if one of our products does not perform as intended), we will always seek to either re-issue the item or refund you. We may require further information to process this request, so we cannot promise a "no questions asked" service. However, customer satisfaction is a priority, and all returns will be processed within a maximum of 14 days of receiving the return.

​

Why buy from ROK Chem?

When it comes to purchasing chemicals and lab supplies, there is a plethora of choices with all vendors offering the same product. ROK Chem stands out as we provide better prices, superior service, and, as a family-owned and operated SME, we genuinely value each and every customer!

​

What if what I need is not shown in the store?

Our stock is constantly evolving, with new products added almost daily. Therefore, we typically have only about 50% of our total stock online at any given time. Please get in touch via phone or email if you require something specific, and if it's not already in stock, we will gladly source it for you.

​

How long does shipping take?

Once an order is submitted, our warehouse team picks, inspects, packs, and ships each order within 24 hours, often sooner. The shipping service used depends on the ordered items and their weight. Some services offer next-day delivery, while others may take 48 hours. We provide real-time email updates on your order's progress and issue a tracking code within 24 hours.

​

Do I need any special licenses or documents to buy from ROK Chem?

In most cases, no. However, depending on your order and quantities, some products may require us to ensure that the end use is legitimate, and we may need to record end user data. In most instances, this can be resolved quickly, and if not, we will issue a full refund.

​

What if there are shipping breakages or damages?

In the rare event that an item arrives damaged, please take a picture if possible and contact us. We will arrange for a replacement or provide a refund, based on your preference. Rest assured that our products are meticulously packaged before shipping.
