Devoluciones

We only accept returns for products that arrived damaged, broken or missing from your order. Because our products are temperature-sensitive research materials, we do not accept returns for change of mind, incorrect ordering, or products that have been opened, used or stored improperly after delivery.

What we accept

• Items damaged or broken in transit.
• Items missing from the shipment.
• Incorrect items sent by us (wrong product or quantity).

What we do not accept

• Change-of-mind returns.
• Products that have been opened, unsealed or used.
• Items damaged by improper storage after delivery.
• Returns requested more than 48 hours after delivery.

How to start a return

1. Email orders@kuulpeps.com within 48 hours of delivery with your order number, the affected items and clear photographs of the damage or a photo of the package contents if items are missing.
2. We review your request and, if approved, send a return reference and address.
3. Send the goods back as instructed. For broken or incorrect items, we cover the return shipping cost.

Refunds and replacements

Once we receive and inspect the returned items, we will either replace them from the next available batch or refund the full item cost, including standard outbound delivery, using the original payment method. Refunds are processed within 14 days of receiving the goods back.

Cold-chain note

Because these are temperature-sensitive research materials, keep any item you intend to return at 2–8°C until it is collected. A vial that has lost its cold chain cannot be resold and may not qualify for a refund or replacement.
