Refund & Return Policy

Last updated: November 10, 2026

All sales are final

Because our products are sealed research materials, we cannot accept returns or exchanges, and orders cannot be cancelled once submitted. Please review your order carefully before checkout.

Damaged, incorrect or missing items

If your order arrives damaged, incorrect or incomplete, contact us within 3 business days of delivery at support@certified-pep.com with:

• your order number
• clear photos of the problem
• a short description of what is wrong

Once we verify the issue, we will send a replacement or refund the affected item to your original payment method. After 3 business days, the order is considered accepted.

Shipping issues

• We are not responsible for delays caused by carriers or weather.
• An incorrect address entered at checkout is the customer’s responsibility.
• Packages lost or stolen after the carrier confirms delivery are not eligible for a refund unless package protection was added at checkout. See our Shipping Policy.
