Refund & Return Policy

All sales are final once shipped

All sales are final once shipped, except verified shipping damage or seller error. Once a product has shipped, we do not accept returns and do not issue refunds or exchanges outside those two exceptions. For safety and chain of custody reasons, opened, used, or unsealed research materials cannot be returned or resold under any circumstances.

Shipping damage or seller error

Inspect your order on arrival. If your order arrives damaged in transit, or if we shipped the wrong item, contact us within 7 days of delivery with your order number and clear photographs of the item(s) and the packaging. Claims made after 7 days, or without photographic evidence and an order number, cannot be honored.

For verified shipping damage or seller error we will, at our sole discretion, replace the item or issue a refund. We may require the affected item to be returned before a replacement or refund is issued. No other returns or refunds are available once a product has shipped.

Canceling before shipment

You may cancel an order any time before it ships by emailing us with your order number, and we will refund the full amount you paid. Unpaid Zelle orders are cancelled automatically if payment is not matched within the payment window shown at checkout. Once an order has shipped it cannot be cancelled and is subject to this policy.

How approved refunds are issued

Refunds are sent by the method you used to pay when practical. If you paid by Zelle, we send a Zelle payment back to the Zelle identity that paid us. If you paid by card, we issue a reversal or credit through the card processor. If we cannot use the original method, we will confirm another method with you in writing. Refund timing depends on the banks or the card processor. Original shipping charges are non refundable except where the order was damaged in transit or shipped in error.

Disputes & chargebacks

Please contact us first. Most issues are resolved quickly. Email orders@bluecheckpeptides.com with your order number and we will respond promptly. Any dispute we cannot resolve is subject to the dispute resolution terms in our Terms of Service, including binding arbitration.
