All sales are final
Our products are research materials whose purity and storage we cannot verify once they leave our hands. For that reason we do not accept returns or exchanges, and we do not refund orders, except as described below or where the law requires it.
Wrong or damaged items
If we sent the wrong item, or an item arrived damaged, email [email protected] with your order number and photos of the item and packaging. Do not send anything back until we reply. We will replace the item or refund it.
Packages that are lost, stolen or damaged in transit are covered by Package Protection if you added it at checkout. See our Shipping Policy.
Cancelling an order
To cancel an order that has not shipped yet, contact us as soon as possible. Once an order has shipped, it cannot be cancelled. Zelle orders still unpaid after 72 hours are cancelled automatically.
How refunds are paid
Approved refunds go back to the original payment method. How long it takes to show up depends on your bank.
