Refund & Return Policy

Because research materials are sensitive to handling, temperature, and chain-of-custody conditions, the integrity of any material that leaves our control cannot be verified on return. We therefore do not accept returned products and do not issue refunds, exchanges, or store credit for buyer's remorse, change of research direction, ordering the wrong item or strength, delays outside our control, or unused inventory.

Returned shipments sent without an approved, documented reporting case cannot be restocked or credited.

A refund is issued in these situations:

• Standard Peptides cannot fulfill an accepted order, or cancels it before shipment.
• A duplicate charge occurs for the same order.
• A shipment qualifies for replacement under the damaged, defective, contaminated, missing, or materially incorrect review process below, but a qualifying replacement is impossible.

Approved refunds are returned to the original payment method for the applicable amount. You are not required to return shipped research material in order to receive an approved refund.

Orders enter processing shortly after submission. Once an order has entered processing it cannot be cancelled or modified, including shipping addresses. Please review your cart, selected strengths, and delivery address carefully before submitting. If we cancel an accepted order before shipment, the applicable amount is refunded.

If a shipment arrives damaged, with compromised packaging or seals, visibly contaminated, missing items, or containing materially different items than those listed on your order confirmation, submit a claim so the shipment can be reviewed. A qualifying claim may result in replacement; where a qualifying replacement is impossible, the applicable amount is refunded to the original payment method. Submitting a claim does not guarantee a replacement or any other outcome.

Required for a report to be reviewed:

• Notice within 1–2 calendar days after the carrier records delivery.
• Your order number and the affected item codes and lot numbers.
• Clear photographs of the outer packaging, shipping label, inner packaging, seals, and the affected vials or containers.
• Retention of all packaging and materials in the condition received until the review is closed.

Submit reports through the Contact page. Reports that are incomplete, submitted after the notice window, or that concern materials already opened, aliquoted, reconstituted, or used cannot be reviewed. Any resolution offered after a review is made at the sole discretion of Standard Peptides.

All materials are supplied for lawful laboratory research use only and are not for human or veterinary use. Materials are shipped to qualified research purchasers who accept the Terms of Service and the Material Transfer Agreement presented at checkout. Non-delivery claims should be raised with reference to carrier tracking before a report is filed.

Claims that are fraudulent, altered, duplicated, abusive, or knowingly false may be denied. We may investigate such claims through lawful means, including review of carrier records, and may restrict or ban the associated account and site access. Nothing in this section prevents you from pursuing a lawful dispute or chargeback with your financial institution.

Nothing in this policy limits or waives any right you have that cannot be waived under applicable law, and nothing here affects any rights you may have with your card issuer or payment provider. Where mandatory consumer or commercial law grants a remedy, that law controls over this policy.

Questions about this policy can be sent through the Contact page.
