Refunds, Replacements & Cancellations

If a product arrives with a visible issue, PaxPeptide will resolve the affected product by issuing a refund or sending a replacement product at no additional cost. Visible issues include, but are not limited to, damaged products or packaging, a compromised seal, leakage, or a visibly incorrect product.

This guarantee applies to visible issues present when the order arrives and is separate from the return limitations for laboratory research materials described below.

Contact support@paxpeptide.com as soon as the issue is noticed. Include the order number, the affected product, and clear photographs showing the visible issue. Keep the affected product and its original packaging until PaxPeptide confirms the resolution.

After reviewing the submitted information, PaxPeptide will confirm whether the affected product will be refunded or replaced. Additional photographs or order details may be requested when needed to verify the issue.

Approved refunds are issued to the original payment method for the affected product. PaxPeptide will notify the customer when the refund has been submitted; the payment provider or financial institution may require additional time to post the credit.

Approved replacement products are sent to the order's original shipping address at no additional product or standard shipping cost unless PaxPeptide and the customer agree to a different address.

Orders may be changed or cancelled before they enter fulfillment review, packaging, or carrier handoff. Once materials are prepared for shipment, changes may not be available.

PaxPeptide may cancel or hold any order that cannot be confirmed for laboratory research use, includes incomplete purchaser or shipping information, or cannot be fulfilled within our United States shipping scope.

Because products are laboratory research materials with handling, storage, and chain-of-custody requirements, products without a visible issue generally cannot be returned. This limitation does not change the visible-product-issue guarantee above.

Do not ship any product back to PaxPeptide unless support provides return instructions. A visibly compromised product will not be required to re-enter sellable inventory.

If inventory availability changes before fulfillment, PaxPeptide may offer an updated shipping timeline, partial fulfillment option, substitution for review, or cancellation.

Any approved remedy is handled case by case and does not change the research-use-only restrictions that apply to every product.
