REFUND POLICY

Due to the research nature of the materials and the impossibility of verifying chain-of-custody or storage conditions after they leave our facility, all sales are final once an order has shipped. We do not accept returns of opened, unopened, or partially used vials.

If your order arrives damaged, is missing an item, or a vial fails visual QC on arrival (broken seal, cracked vial, leaking, or contents visibly compromised), contact us within 72 hoursof delivery with photos and your order number. We will replace the item free of charge or issue a refund at our discretion.

You may cancel an order for a full refund before it has shipped. Once a tracking number is generated, the order is considered shipped and Section 1 applies. To cancel, emailinfo@metracorelabs.comwith your order number as soon as possible.

If a package is returned to us because of an incorrect address, refused delivery, or repeated failed delivery attempts, we will contact you to arrange re-shipment. Re-shipping fees will apply. If we cannot reach you within 14 days, we will refund the order minus original shipping and a 15% restocking fee.

If tracking shows a package as lost in transit, contact us and we will open a carrier investigation. Once the carrier confirms the package is lost, we will re-ship or refund at your choice.

Orders that include optional shipping protection at checkout are covered for loss, theft, or damage in transit per the terms displayed at checkout. Claims must be filed within the window shown on your order confirmation.

Payments are recorded against the purchaser's research account and order ID. Metracore Labs maintains order, payment, acknowledgement, and fulfillment records for compliance review. For Cash App payments there is no card issuer or automated processor to dispute a charge with. For card payments, please contact us before opening a dispute with your bank. Contact us directly and we will resolve the issue. Attempting to reverse or claw back a payment without contacting us first may result in permanent account suspension and legal action to recover disputed funds and associated costs.

Approved refunds are issued by us directly, returned through the same payment method you used. Cash App refunds go back to the handle the payment came from, and card refunds are returned to the card charged. We will ask you to confirm that destination before sending. Each refund is logged against your order with the date, amount, and a refund reference. Refunds are typically sent within a few business days of approval; the exact timing depends on how quickly the transfer clears on your side.

To request a replacement, cancellation, or refund, emailinfo@metracorelabs.comwith your order number.
