Return & Refund Policy

Last updated: September 2026

We stand behind our products and want customers to feel confident ordering from M1 Labs. Please review the following policy before requesting a return or sending a product back.

1. Return Window

Return requests must be submitted within 30 days of the date your order was delivered.

To qualify for a return, proof of purchase directly from M1 Labs is required. Products purchased through another retailer, marketplace, or authorized seller must be returned through the original place of purchase and are subject to that seller’s return policy.

2. Unopened Products

Unopened products may be returned within 30 days of delivery when they are:

• Unused

• Sealed

• In their original packaging

• In their original condition

Products that have been opened, used, damaged, altered, or improperly stored may not qualify unless covered by the First-Purchase Guarantee described below.

3. First-Purchase Guarantee

If you try an M1 Labs product for the first time and are not satisfied, you may request a refund for one opened container of that product within 30 days of delivery.

The First-Purchase Guarantee is limited to:

• One opened container per product

• One claim per customer

• One claim per household

• One claim per shipping address

• Products purchased directly from M1 Labs

Additional opened containers of the same product are not eligible for a refund. Products that you have purchased previously are also not eligible under the First-Purchase Guarantee.

Do not mail an opened product back unless the M1 Labs support team specifically asks you to return it.

M1 Labs reserves the right to deny guarantee claims that appear fraudulent, abusive, excessive, or inconsistent with the purpose of this policy.

4. How to Request a Return

Before sending anything back, email sales@m1labs.com with:

• Your full name

• Your order number

• The product you would like to return

• Whether the product is opened or unopened

• The reason for the return

If the return is eligible, our team will provide return authorization, instructions, and the appropriate return address.

Returns sent without prior authorization may not be accepted or refunded.

5. Return Shipping

Customers are responsible for return shipping costs unless the order arrived damaged, defective, missing, or incorrect.

Original shipping charges, including expedited shipping charges, are nonrefundable unless the return is the result of an error made by M1 Labs.

We recommend using a trackable shipping method and keeping the tracking information until the return is completed. M1 Labs is not responsible for return packages that are lost, stolen, misdirected, or damaged while in transit.

6. Damaged, Defective, Missing, or Incorrect Orders

Inspect your order as soon as it arrives.

If an item is damaged, defective, missing, or incorrect, email sales@m1labs.com within 7 days of delivery. Include:

• Your full name

• Your order number

• A description of the issue

• Clear photographs of the product

• Photographs of the shipping box and packaging when applicable

After reviewing the issue, M1 Labs may provide an appropriate replacement or refund at no additional cost to you.

Products should not be discarded until our team has reviewed the claim and confirmed that they do not need to be returned.

7. Nonreturnable Items

The following items are not eligible for return or refund:

• Gift cards

• Samples

• Clearance or final-sale products

• Bulk or wholesale purchases

• Products purchased from another retailer

• Products returned more than 30 days after delivery

• Multiple opened containers of the same product

• Products damaged through misuse or unauthorized modification

• Products damaged because of improper use or storage

• Returns sent without authorization

• Shipping charges, except when the return results from an M1 Labs error

Additional items may be considered final sale when clearly identified as such before purchase.

8. Subscription Orders

Canceling a subscription prevents future recurring orders from being created, but it does not automatically cancel or refund an order that has already been processed.

If a subscription order has already been created, contact sales@m1labs.com as soon as possible. We will attempt to cancel the order before it enters fulfillment, but cancellation is not guaranteed once processing has begun.

Delivered subscription orders are subject to the same eligibility requirements, return window, exclusions, and First-Purchase Guarantee described in this policy.

Canceling a subscription does not retroactively apply to previously processed or delivered orders.

9. Refund Review

Returned products are inspected after they are received. We will notify you when your return has been reviewed and whether the refund has been approved or denied.

M1 Labs reserves the right to reduce or deny a refund if:

• The product does not meet the return requirements

• The returned product differs from the authorized return

• Items are missing from the return

• The product has been damaged after delivery

• The request shows signs of fraud, misuse, or policy abuse

10. Approved Refunds

Approved refunds are issued to the original payment method.

Original shipping and expedited-delivery charges are not included unless the return resulted from a damaged, defective, missing, or incorrect order.

Please allow 5–10 business days for an approved refund to appear after it has been issued. Your bank, credit-card company, or payment provider may require additional processing time.

M1 Labs cannot issue a refund to a different card, bank account, or payment method.

11. Exchanges

M1 Labs does not process direct product exchanges.

If you would like a different product, request a return for the eligible item and place a separate order for the new product.

12. Refused and Undeliverable Packages

Packages refused by the recipient or returned because of an incorrect, incomplete, or undeliverable address are not automatically eligible for a full refund.

If a returned package is received in acceptable condition, the product cost may be refunded after deducting original shipping charges and any additional carrier or return costs.

Additional shipping charges may apply if you ask us to resend the order.

13. Purchases From Other Sellers

This policy applies only to purchases made directly through the official M1 Labs website.

If you purchased an M1 Labs product from Amazon, a retail store, healthcare provider, gym, marketplace, or another authorized seller, contact that seller directly. Their return and refund policies apply to the transaction.
