Refund & Return Policy

All sales are final once shipped

Once a product has shipped, we do not accept returns and do not issue refunds or exchanges, except for verified shipping damage or seller error as described below. 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 request cancellation before an order ships by emailing us with your order number. Once an order has shipped it cannot be canceled and is subject to this policy.

How approved refunds are issued

Where a refund is approved for verified shipping damage or seller error, it is issued to the original payment method. 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 within one business day.
