Every batch is tested for identity and purity by an independent third-party lab before it's listed for sale. Anything that doesn't clear the 99%+ purity threshold never makes it to a listing.
A certificate of analysis is a lab report confirming a batch's identity and purity. Search our certificates of analysis page by product name for the batch-specific certificate on file, when one has been published. The Sample COA on our testing page illustrates the format only and is not any specific vial's certificate.
Store lyophilized vials cool, dark, and dry. Once reconstituted, keep refrigerated. Handle only in a laboratory research setting with appropriate protective equipment.
Orders ship in plain, unbranded outer packaging with no reference to the contents. A tracking number is provided once the order ships.
