Refund Policy

Because our products are research reference materials with strict chain-of-custody requirements, we cannot accept returns of opened, unsealed, or previously shipped vials. Once a package leaves our facility, it is considered outside a verifiable chain of custody and is not eligible for resale or restocking.

Orders may be cancelled without penalty at any time before the shipping label is generated (typically within the first several hours after checkout). To cancel, email hi@gammapeps.com with your order number. Once an order has shipped, cancellation is no longer available. Damage and loss claims are handled separately under the sections below.

Account and order information is subject to review before fulfillment. If we determine that an order does not meet our research-use-only eligibility criteria, we will cancel it and refund the full amount, including shipping, to the original payment method. No restocking or cancellation fee applies to orders we cancel for eligibility reasons.

If your order arrives with a broken seal, cracked vial, or visible transit damage, contact hi@gammapeps.com within 7 days of delivery. Include your order number, photos of the outer packaging, and photos of the affected items. Verified damage claims are replaced free of charge or refunded to the original payment method at our discretion.

If tracking shows a package as delivered but it cannot be located, first check with your carrier and neighbors. If the package remains missing after 48 hours, email us with your order number. Orders purchased with Shipping Protection are eligible for a free replacement or full refund. Orders without Shipping Protection are handled case-by-case and subject to carrier claim outcomes.

If you receive an incorrect item, contact us within 7 days of delivery. We will arrange a prepaid return of the incorrect item and ship the correct item at no additional cost.

For product-integrity reasons, the following are never eligible for return or refund once shipped: opened vials, products with broken seals, custom or special-order compounds, and items reported more than 7 days after delivery.

We ask that you contact hi@gammapeps.com before initiating a payment dispute. We respond to all support inquiries within one business day and can usually resolve issues faster than a formal chargeback process.

Approved refunds are issued to the original payment method within 5–10 business days after approval. Depending on the payment provider, the credit may take additional time to appear on your statement.
