Return Policy
EHZ US Warehouse
Last updated: June 3, 2026
All Sales Final
Due to the nature of research compounds and strict chain-of-custody requirements, all sales are final. We do not accept returns of opened, used, or handled products under any circumstances.
Damaged or Incorrect Orders
We will issue a replacement or store credit in the following circumstances only:
- Damaged in transit: Product arrives with destroyed packaging, broken vials, or compromised contents.
- Incorrect item shipped: You receive a product that does not match your order.
Claims must be submitted within 24 hours of the delivery date. Contact us through the Site’s contact page with your order number, a description of the issue, and photographs of the damaged or incorrect item and packaging. We will review and respond within 3–5 business days. Approved claims will receive a replacement or store credit at our discretion. Cash refunds are not issued unless a replacement cannot be fulfilled.
Lost or Missing Packages
If your package has not arrived and tracking has not updated, contact us within 2 business days of the expected delivery date. EHZ US Warehouse is not responsible for packages confirmed delivered to the address provided at checkout.
Order Cancellations
Cancellations are accepted only before fulfillment begins. Once an order has been picked, packed, or shipped, it cannot be cancelled. Contact us immediately through the Site’s contact page if you need to request a cancellation.
Chargebacks
EHZ US Warehouse maintains records of all transactions and will contest any unjustified chargeback. Initiating a fraudulent chargeback may result in a permanent purchasing ban. If you have a concern with your order, contact us directly — we will work to resolve it.
