(06) Questions
Good to know.
Where can I buy methylene blue in the UK?
Directly from Cereblue. Our methylene blue is manufactured in the UK and sold in 50 ml dropper bottles at 1%, 3% and 5% concentrations. Order before 1 pm, Monday to Friday, for next-day delivery in the UK.
What is methylene blue?
Methylene blue is a synthetic blue dye first made in 1876. It is widely used in laboratory research into colour-changing redox reactions, light-driven chemistry and sensing. Our research notes explain these topics and link to the original publications.
What is the difference between 1%, 3% and 5%?
The percentage is the concentration of the solution: 1% is 10 mg per ml, 3% is 30 mg per ml and 5% is 50 mg per ml. All three come in the same 50 ml dropper bottle and are made to the same standard. Choose the concentration your established research protocol specifies.
What is the gold formula?
A second formula of Cereblue Methylene Blue, sold alongside the Original. Its label reads “Nano Liquid Gold Infusion Formula”. It comes in the same 50 ml dropper bottle and the same three concentrations, 1%, 3% and 5%, each with its own price. Choose it with the Formula switch beside the strengths on the product page.
When will my order be dispatched and delivered?
Orders placed before 1 pm UK time, Monday to Friday, are posted the same day and delivered the next day. Nothing is posted at weekends: an order placed after 1 pm, or on a Saturday or Sunday, goes out the next working day and arrives the day after that. UK delivery is free on every order.
Can I have it delivered regularly?
Yes. On the product page, choose the subscription instead of a one-time purchase and pick how often a bottle is delivered. The price of each delivery is shown there before you add it to your bag, and you can manage the subscription from your account.
Can I return my order?
Yes. Unopened, sealed bottles can be returned within 30 days. Return postage is paid by the customer and there is no restocking fee. See the returns policy for details.
Where can I find quality and testing information?
Our standard is set out above, and our research note on concentration, purity and batch testing explains how to read it. For documentation questions, contact us with the batch number on your bottle.
