Refund and Returns Policy

Last updated: August 19, 2026 · Version 1.1

1. Summary

For safety and quality assurance reasons, we don’t accept general returns on research materials once they’ve shipped. That said, we stand behind every lot we sell. If a product arrives damaged, incorrect, or fails to meet our published purity or weight specifications, contact us and we’ll make it right.

2. Time limits

Contact us as soon as possible, but no later than 30 days after delivery, to make a claim under this policy. Approved refunds are issued to the original payment method within 10 business days of approval; your bank or card issuer may take additional time to post the credit.

3. Returns

We do not accept general returns on research materials once an order has shipped — once a product has left our custody we can no longer verify how it was stored or handled. Cancellations before shipment are always free of charge — see Section 5. If your order arrives damaged or incorrect, or fails to meet our purity or weight guarantee, see Sections 4 and 6 below.

4. Damaged, incorrect, or defective on arrival

Contact us as soon as possible, but no later than 30 days after delivery, with your order number, the lot number from the vial or packaging, and photographs showing the issue and the packaging as received, so we can make it right.

5. Order cancellation

Orders may be cancelled at no charge at any time before shipment. Payment is refunded in full to the original payment method; no cancellation fee applies.

6. Purity and weight guarantee

We publish a Certificate of Analysis for every lot we sell. If independent testing shows a product does not meet the specifications below, contact us so we can make it right.

How to make a claim: have the product tested by one of the laboratories listed in Section 7, then contact us as soon as possible, but no later than 30 days after delivery, with the full test report, your order number, and the lot number of the material tested. If the report shows purity below 98% or weight more than 10% below advertised, we’ll make it right. We are not able to cover the cost of testing.

7. Accepted testing laboratories

Independent test reports will be accepted from the following laboratories:

• Freedom Diagnostics
• Janoshik Analytical
• MZ Biolabs
• TrustPointe Analytics
• Vanguard Laboratory

8. What is not covered

• Products opened, reconstituted, diluted, transferred, or otherwise handled after delivery, or where the issue may have arisen from mishandling
• Products stored outside the conditions stated on the product page
• Changes in physical appearance that do not indicate a specification failure — some materials may gel, cloud, or show precipitation during handling
• Products not purchased directly from altitudeaminos.com (for example, through a reseller or third party)
• Claims submitted more than 30 days after delivery
• Shipping charges, except where the claim arises from our error

9. Payment disputes — contact us first

If something is wrong with your order, tell us. We would much rather fix it than have you fight your bank about it.

We hold every order to the guarantees above, and we keep detailed records — lot numbers, fulfillment photographs, and delivery confirmation — so we can usually get to the bottom of it and resolve it quickly.

Opening a dispute with your card issuer or bank before contacting us is almost always the slower route: it locks the transaction, removes our ability to simply refund or reship, and typically takes your issuer weeks to resolve. A message to support@altitudeaminos.com gets you a person.

You retain every dispute right your card issuer or bank gives you, and nothing in this policy asks you to waive them. We simply ask for the chance to fix it first. We reserve the right to decline future orders where we have clear evidence of fraudulent activity.

10. How to make a claim

Email support@altitudeaminos.com with your order number, lot number, a description of the issue, and any photographs or test reports. We’ll investigate and respond quickly.
