This page covers sending a delivered order back to us. How approved refunds are issued is covered on our Refunds & Returns page. Products are sold as research materials only; see the Research Disclaimer.

All Sales Final

Due to the sensitive nature of research products and to maintain the integrity of our supply chain, all sales are final. We do not accept returns of opened or unopened products once they have shipped.

What We Do Accept

If your product arrives damaged, defective, or incorrect, we will replace the product or issue a refund at our discretion. This is the only category of return we accept.

Report It Within 7 Days

Contact us within 7 days of delivery through our contact form. A report needs all of the following before we can review it:

  • Your order number.
  • The delivery date.
  • Photos of the vial and the packaging that show the damage, defect, or the wrong item received.
  • What you ordered and what actually arrived.

What Happens Next

  1. We review the report and the photos you sent.
  2. We tell you whether the item will be replaced or refunded, and on which terms.
  3. If the item has to come back to us, we email you where to send it and what to include. Wait for those instructions before mailing anything.

Not Eligible For Return

  • Products that have been opened or used.
  • Products reported more than 7 days after delivery.
  • Orders you simply changed your mind about. All sales are final once an order has shipped.

Before Your Order Ships

Orders may be cancelled for a full refund before they are shipped. Once an order has been shipped, it cannot be cancelled and cannot be returned.

Pickup Orders

If your order was placed with an in-person pickup code, contact the person who gave you the code about anything wrong with the item. They arranged the handoff and can sort out a replacement or refund with us.

Refund Timing

Approved refunds are issued to the original payment method within 5-10 business days of approval. More detail is on the Refunds & Returns page.
