Refund Policy
Last updated October 28, 2026
Because our products are research materials, all sales are final once an order has been handed to the carrier, with the exceptions below.
Purity and content guarantee
You may request a refund or replacement if independent third-party testing shows that a product is below 99% purity, fails to meet its stated identity, or contains less than 90% of the labelled amount (for example, less than 4.50 mg in a vial labelled 5 mg).
Send us the certificate of analysis. It must be verifiable on the testing laboratory's own website. Once a vial's cap has been removed, refunds and replacements are available only when these testing criteria are met.
Broken or damaged vials
To qualify for a replacement for vials that arrive broken, send us a video showing the package being opened and the broken contents inside. Without that unboxing video we cannot replace damaged items.
Wrong or missing items
If something is missing or different from your confirmation, email us with your order reference and photos by 11:59 PM (Central Time) on the third day after delivery, and we will make it right. For example, if your order is delivered on May 13, email us by 11:59 PM on May 16.
How refunds are paid
Approved refunds are returned to the original payment method where possible, or as store credit if you prefer. Network or payment-service fees are not refundable.
Chargebacks
Please contact us before disputing a payment so we can resolve the problem. Orders under dispute are not eligible for further replacements, and we may decline future orders from accounts that file unfounded disputes.
