Refunds and order issues

A customer may request cancellation by emailing support before fulfillment begins. Once a shipment has been handed to the carrier, the order can no longer be cancelled.

All sales are final. Because research materials cannot be placed back into inventory while preserving product integrity and chain of custody, physical returns are not accepted, including unopened products.

Do not mail products to the business correspondence address. Unauthorized shipments will not be accepted or credited.

Transit damage, an incorrect item, or another verified fulfillment problem may qualify for a replacement or refund without a physical return. Contact support within 48 hours of delivery and provide the order number and photographs of the item, label, packaging, and shipping container. Vyse Labs will review the evidence before approving a remedy.

Approved refunds will be issued to the original payment method within five business days after approval. The customer’s bank or card issuer may require additional time to post the credit. Original shipping charges are not refundable unless the refund results from a verified fulfillment error or applicable law requires otherwise.

Customers should contact support promptly so a problem can be investigated and documented. This policy does not limit rights or remedies that cannot lawfully be waived, and it does not restrict a customer from contacting a card issuer.
