Good to know about Maylene

All products sold by Maylene are intended for laboratory research purposes only and are not intended for human consumption, veterinary use, or any other application outside of controlled research environments. Buyers must be at least 18 years of age, be a qualified researcher, laboratory professional, or authorized representative of a research institution, and possess appropriate credentials and facilities for handling research chemicals. Products can differ in format, contents, and documentation, so buyers should check product identity, specifications, batch documentation, and packaging and delivery requirements before ordering. The company provides published reports and certificates for some products, but not every product has a published report, and a product-and-strength match does not independently verify the batch currently in stock.
