Returns & refunds

Last updated: July 2026

Product integrity

Because our products are research materials whose integrity depends on proper handling and storage, we are unable to accept returns of opened, used, or unsealed vials. This protects the quality and safety of every order we ship.

Damaged or incorrect orders

If you receive a damaged vial, the wrong item, or a defective product, contact us at support@glp3.fit within 7 days of delivery with your order number and a photo of the issue. We will replace the affected items or issue a refund at our discretion.

Order cancellation

Orders can be canceled for a full refund any time before they are dispatched. Once an order has shipped, it can no longer be canceled.

Refund processing

Approved refunds are issued to your original payment method. Please allow 5–10 business days for the refund to appear, depending on your bank or card issuer.

We want you to be confident in every order. If something isn't right, reach out and we'll work with you to resolve it.
