Refund Policy

Unopened vials in original, sealed condition may be returned within 14 days of delivery for a refund of the item price. Return shipping is the buyer's responsibility and is not reimbursed. Refunds are issued to the original payment method once the returned item is received and inspected.

Vials that have been opened, reconstituted, or otherwise removed from their sealed state cannot be returned or refunded. This applies regardless of whether the reagent was used, and is a product-integrity requirement rather than a preference — once a seal is broken, the chain of custody and storage conditions can no longer be verified.

If an order arrives incorrect or visibly damaged, contact support@pepgo.orgwith your order number and photo evidence within 12 hours of delivery. Verified claims are resolved with a replacement shipment or a full refund, at the customer's preference.

1. Email support@pepgo.org with your order number and a description of the issue.
2. Include photo evidence for damage, exposure, or incorrect-item claims.
3. We respond within one business day with return instructions or a resolution.
