About a certificate

So we can find it quickly, include:

• The lot code from the vial label, or the document ID from the certificate
• Where you bought the product
• A photo of the label, if the code will not open

Questions about a product itself, an order or a refund are for the seller you bought from.

For brands

Tell us:

• Your brand name and website
• The products and how many SKUs you sell
• Which tests you need, if you know
• How your vials are labelled today
