# 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.
