Refund & Return Policy

Last updated September 30, 2026.

Overview

We accept returns of unopened, sealed products within 30 days of delivery. If something is wrong with your order, contact us and we will make it right.

30-Day Returns

To be eligible for a return, the item must be:

  • Returned within 30 days of the delivery date
  • Unopened, with the original seal intact
  • Unused and stored properly
  • In its original packaging, with proof of purchase (your order number)

Return shipping is paid by the customer, unless the return is due to our error (see below). We recommend a trackable shipping service, since we can't refund a return we don't receive.

How to Start a Return

Email support@nubiogen.com with your order number and the items you want to return. We will reply with a return authorization and the return address.

Please do not send items back without an authorization. Packages sent without one may not be accepted.

Items That Can't Be Returned

  • Opened, used or unsealed products
  • Products that have been altered or improperly stored
  • Items returned more than 30 days after delivery
  • Items marked final sale
  • Gift cards

Damaged, Defective or Incorrect Items

Please inspect your order when it arrives. If an item is damaged, defective, or not what you ordered, contact support@nubiogen.com within 48 hours of delivery with:

  • Your order number
  • A description of the issue
  • Photos of the shipping box and label
  • Clear photos of the item received

If the problem is our error, we will send a replacement or issue a refund, and we cover the return shipping.

Refunds

Once we receive and inspect your return, we will email you to confirm whether it is approved.

Approved refunds go back to your original payment method: card refunds to your card, Zelle refunds by Zelle. Please allow up to 10 business days after approval; your bank or card issuer may take additional time to post it.

Original shipping charges are non-refundable unless the return is due to our error.

Lost, Stolen or Carrier-Delayed Packages

Once an order is handed to the carrier, delivery is under the carrier's control. If your package is marked delivered but missing, delayed, or misdelivered, please contact the carrier first, then contact us and we will help review the situation.

European Union 14-Day Cooling-Off Period

If merchandise is shipped into the European Union, you may have the right to cancel or return your order within 14 days for any reason, subject to applicable law. The item must be unused, unopened and in its original packaging, with proof of purchase.

Payment Disputes and Chargebacks

If you have an issue with your order, please contact us before filing a chargeback. We can usually resolve legitimate concerns quickly and directly.
