Refunds & returns
Most research products cannot be returned after leaving our facility because storage, handling, chain of custody, and integrity cannot be verified.
All sales are final.
Unless an order arrives damaged, contains the wrong item, is missing an item, or Zen Aminos determines that another fulfillment error occurred, purchases are considered final once shipped.
How returns, refunds, and order issues are handled.
Each eligible claim is reviewed based on the order record, shipment details, product condition, and information provided to support.
Returns
Zen Aminos does not accept routine returns of products that have been shipped or delivered.
- Opened products are not eligible for return.
- Used or reconstituted products are not eligible for return.
- Products removed from original packaging are not eligible for return.
- Products that have been altered, mishandled, or improperly stored are not eligible for return.
Refunds
Refunds are not automatically available once an order has entered fulfillment or shipped.
When a refund is approved, it is generally issued to the original payment method whenever possible. Bank and payment-provider processing times may vary.
Order Cancellations
Cancellation requests must be submitted as soon as possible after an order is placed.
Once processing, packing, or shipment preparation begins, Zen Aminos cannot guarantee that the order can be canceled or changed.
Damaged or Incorrect Items
Contact support promptly if an order arrives damaged or contains an incorrect item.
- Provide the order number.
- Clearly describe the issue.
- Keep all packaging and shipping materials until the claim is reviewed.
- Photos of the package, label, packaging materials, or affected item may be requested.
Missing Items
If an item appears to be missing from the shipment, contact support with the order number and a description of what was received.
Zen Aminos will compare the report with the order and fulfillment record before determining an appropriate resolution.
Lost or Delivered Packages
When tracking shows delivered but the package cannot be located, first check with household members, neighbors, building staff, mailrooms, and the shipping carrier.
A carrier claim or investigation may be required before Zen Aminos can consider a replacement, credit, or other resolution.
Unauthorized Returns
Do not mail products back to Zen Aminos without written approval and return instructions from support.
Unauthorized returns may be refused and may not qualify for a refund, replacement, or store credit.
Chargebacks & Disputes
Customers should contact Zen Aminos first and allow the support team a reasonable opportunity to review and resolve an order issue.
Fraudulent claims, false statements, or improper payment disputes may result in account restriction or refusal of future service.
Approved resolutions
Each qualifying issue is reviewed individually. Depending on the confirmed fulfillment error and order circumstances, Zen Aminos may offer a replacement, account credit, a partial refund, or a full refund.
Report an order issue
Include your order number, billing email, and a clear description. We will review the order and explain the next steps.
