RETURNS
Refund and Returns Policy
Last updated: October 21, 2026 · Version 1.3
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 by the same payment method you used, within 10 business days of approval or, where we need details from you to send the refund, of receiving them. Zelle® payments cannot be reversed, so a Zelle® refund is sent as a new Zelle® payment, only to an email address or mobile number enrolled in the name of the person who sent the original payment. Cryptocurrency refunds are sent to a wallet address you confirm to us in writing, for the US-dollar amount credited to your Order, not the number of coins or tokens. Network (gas) and exchange fees you pay to send a payment are not received by us and are not refunded. We are not responsible for a refund sent to details you confirmed that prove to be incorrect. If we have reason to believe a payment was not authorized by the holder of the account it came from, we may hold the refund until that is resolved.
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. Any amount we received is refunded in full within 10 business days, by the method described in Section 2; 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.
| Specification | Guarantee |
|---|---|
| Purity | Not less than 99% |
| Net peptide weight | Not more than 10% below the advertised amount |
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 99% 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.
