Returns & refunds

You can cancel an order at any time before it ships by contacting us with the order number. If you have paid, we refund you in full.

Because research materials can’t be safely resold once they have left our control, we don’t accept returns of items that arrive as ordered.

If an item arrives damaged, differs from what you ordered or its lot number doesn’t verify on our Verify page, contact us promptly with your order number, and send photographs of the packaging and vials. We’ll replace the item or refund it.

Refunds are made to the original payment method. How long they take to appear depends on that method.
