All Sales Are Final

Due to the research-grade, temperature-sensitive, and perishable nature of our products, all sales are final. PT Research Labs does not accept returns, exchanges, or issue refunds for any product once an order has been shipped. This policy is consistent with industry standards for research compounds and is necessary to maintain product integrity and chain-of-custody requirements.

By submitting an order inquiry, you acknowledge and agree that you have read this policy and understand that no returns or refunds will be issued except in the limited circumstances described below.

Exceptions — Damaged or Incorrect Orders

PT Research Labs will issue a replacement or store credit (at our discretion) only in the following circumstances:

• Damaged in transit: The product arrived visibly damaged due to carrier mishandling. You must notify us within 48 hours of delivery with photographic evidence of the damage.
• Wrong item shipped: You received a product that is materially different from what you ordered. You must notify us within 48 hours of delivery.
• Missing item: An item listed on your order confirmation was not included in the shipment. You must notify us within 48 hours of delivery.

To initiate a claim under these exceptions, contact us at [email protected] with your order reference number, a description of the issue, and supporting photographs. Claims submitted after 48 hours of delivery will not be accepted.

Non-Refundable Circumstances

The following circumstances do not qualify for a refund, replacement, or store credit under any conditions:

• Change of mind or ordering error by the customer
• Products that have been opened, used, or reconstituted
• Products damaged due to improper storage or handling by the customer
• Orders where the customer provided an incorrect shipping address
• Delays or losses caused by the carrier after confirmed handoff
• Dissatisfaction with research results or outcomes

Order Cancellation

Orders may be cancelled only if they have not yet been processed for fulfillment. Once an order has been confirmed and preparation has begun, cancellation is not possible. To request a cancellation, contact us immediately at [email protected] with your order reference number. We will make every effort to accommodate cancellation requests received before fulfillment begins, but cannot guarantee cancellation once processing has started.
