Getting startedHow does Maylene work?
Browse the collection, open a product to check its labelled content and format, then add your selection to the basket. Checkout creates a saved payment request. Our team confirms each payment after checking it.
Product informationWhere can I find product documentation?
Available certificates and reports are in our Certificates library and on the relevant product pages. Check that the report and product details match the item you are researching.
Explore product reportsYour accountDo I need an account to order?
You can shop and check out as a guest. Email verification protects saved addresses, account details and order history, but does not stop you shopping.
Delivery destinationsWhere do you ship?
UK shipping is free with no minimum order. Destinations outside the UK have a flat £35 shipping charge per order. Select your destination at checkout to see the available delivery option.
Clear pricingHow does the pricing work?
Current prices are shown in pounds sterling on each product page. Where a product has quantity pricing, its product page and basket show the applicable price. Review your final total at checkout.
Order changesWhat if I need to change my order?
Contact Maylene support with your payment request or order reference. Payments, cancellations and refunds are reviewed by staff; they are not processed automatically.
The collectionWhat products can I browse?
The collection includes research pens and product bundles, with the compound and labelled content shown for each item. Browse the live catalogue for current products and availability.
Product formatsDo you offer pens and bundles?
Yes. Use the Research pens and Product bundles collections to compare the available formats. Each listing describes the specific product and its contents.
Research calculationsWhere is the pen calculator?
Our existing calculator is available from the Pen calculator link on this page. It explains total clicks from zero and additional clicks from a stated starting value. It is a calculation tool, not a dosing recommendation.
Open the pen calculatorPaying for an orderHow do I pay?
Continue from checkout to your saved payment request and follow the payment instructions there. Staff confirm receipt manually. Creating or returning from a payment request does not mark an order as paid.
Returning to your basketCan I edit my basket after opening a payment request?
Yes. Your basket stays editable, with saved items and checkout details. A fresh checkout creates a new payment request. Earlier requests remain separately traceable for staff.
Shipping costsIs UK delivery really free?
Yes. UK shipping is free on every order, with no minimum. International shipping is £35 per order. Prices remain in GBP for both.
Intended useAre these products intended for personal use?
No. The products are for laboratory research only, not for human or veterinary use, consumption or application. Maylene does not provide a prescription or a medical treatment service.
