Purity Guarantee

Every product we sell is backed by independent third-party HPLC testing. If you submit analytical results from an accredited laboratory showing that a product falls below our stated purity specification, we will provide either a full product replacement or a store credit refund at your choice.

To submit a purity claim:

• Send your third-party test results to support@lumenresearchlab.com or via Telegram
• Include your order number and batch number
• We will review and respond within 48 hours

Shipping Damage or Loss

If your order is damaged in transit or lost by the carrier:

• Damaged shipments: Contact us with photos of the damage and your tracking number. We will ship a replacement at no additional cost.
• Lost shipments: If tracking shows no delivery after the estimated window, contact us with your order number. We will reship or issue store credit.

Claims for shipping damage or loss must be submitted within 30 days of the order date.

Store Credit

Refunds are issued as store credit applicable to future orders. Store credit does not expire. In exceptional circumstances, alternative refund methods may be considered at our discretion.
