What to include in your email

• Your order number, if your question is about an order.
• The product name and lot number, if your question is about a specific vial or its certificate of analysis.
• For an item damaged in shipping: clear photos of the damaged item and its packaging, including the shipping label, sent within 48 hours of delivery.
• For a wrong item or a lost shipment: what you ordered and, for a wrong item, a photo of what you received.
• The email address used at checkout, if it is different from the one you are writing from.

Items damaged in shipping, wrong items and lost shipments are replaced. We do not otherwise accept returns or issue refunds.

All support is handled by email. Certificates of analysis are published on our COA page and are not included with orders.
