# Return & Refund Policy
Last updated: August 20, 2026
We want you to be comfortable trying H2X. Because this is a dietary supplement, we also have to protect other customers.
## 30-day window
You may request a refund within 30 days of delivery for unopened product that is still in its original, sealed packaging.
## What we cannot take back
For health and safety reasons we cannot accept returns of opened, used, or tampered product, except when the item arrived damaged or defective.
## Damaged or defective
If a product arrives damaged or defective, email us within 7 days of delivery with your order number and photos. We will replace it or refund the purchase price, including original shipping, at no cost to you.
## How to start a return
Email info@h2xusa.com with your order number and the reason for the return. We will send a Return Authorization and the San Marcos warehouse address. Do not ship a return without that authorization.
Returns should be sent to:
A2X LLC / H2X Returns
968 Rancheros Drive, Suite P
San Marcos, CA 92069
## Refunds
Once we receive and inspect an authorized return, we issue a refund to the original payment method within 5–10 business days. Original outbound shipping is refunded only when the return is for our error, damage, or a defect. Return postage is your responsibility unless we agree otherwise.
## Subscriptions
Refunds on a subscription shipment follow this same 30-day unopened rule. Canceling a subscription does not automatically refund boxes that already shipped. See [Cancellation](/cancellation).
## Chargebacks
If something is wrong with an order, email us first. We will fix it under this policy.
