Return policy

Last updated January 1, 2026

Summary All sales are final once an order has shipped. Damaged, defective, or incorrect orders must be reported within 48 hours of delivery for a replacement or store credit.

Eligible returns

All sales are final. Because our products are sold for research use and require careful handling and storage, we do not accept returns or exchanges once an order has shipped.

Non-returnable items

Damaged, defective, or incorrect orders are the only exception to this (see below). All other products, once shipped, are not eligible for return or exchange.

Damaged or incorrect orders

If your order arrives damaged, defective, or incorrect, contact us within 48 hours of delivery at info@gladdixpeptides.com with your order number, photos of the product and packaging, and a description of the issue. Approved claims receive a replacement or store credit, at our discretion.

Lost or stolen packages

We are not responsible for packages that the carrier marks as delivered. If your package is lost in transit, contact us and we will help you file a claim with the shipping carrier. Cancellations are accepted only before an order has been processed or shipped.

Refunds

Refunds are considered only when a product arrives damaged or unusable, or the wrong item was shipped; approved refunds are issued as store credit or to your original payment method, reviewed case by case. You are responsible for storing and handling products properly after delivery, and we are not liable for degradation caused by improper storage. We may update this policy at any time; placing an order means you agree to the version in effect at the time of your order.
