Refund & Return Policy

PepGuide may authorize a refund or replacement in the following situations:

• Damage in transit that is documented and reported promptly upon delivery.
• Receipt of an incorrect Product.
• A quantity discrepancy between what was ordered and what was received.
• A verified product-quality issue supported by applicable analytical documentation.
• A shipping error caused by PepGuide.

• Products that have been opened, altered, diluted, combined, or reconstituted after receipt, except where required by law.
• Products damaged after delivery due to improper handling or storage by the recipient.
• Change-of-mind returns after a Product has shipped.
• Refusal of delivery without prior authorization.
• Original shipping charges, except where a refund is required by law or the shipment issue resulted from an error by PepGuide.

All refund and return requests must be initiated through the Contact page before any Product is returned. Please include your order number, the item(s) affected, and a description of the issue. Photographs of damaged shipments or Products are helpful and may be requested.

Requests should be submitted within a reasonable time following delivery. PepGuide may decline requests submitted after an unreasonable delay.

Do not return any Product without prior authorization. Where PepGuide determines that a return is appropriate, we will provide written return instructions and, where PepGuide determines that the return resulted from our fulfillment error, PepGuide may provide return instructions or a prepaid return label, as appropriate.

Approved requests will be resolved through replacement or refund, as appropriate based on the circumstances and applicable law. Refunds are issued to the original method of payment. Processing times depend on the payment provider.

Products are supplied for laboratory research only. Once Products have been opened, altered, diluted, combined, or reconstituted, PepGuide can no longer verify their identity, purity, or condition, and such Products are generally not eligible for return or refund except where required by law.
