Frequently asked questions
Everything about ordering, certificates of analysis, payment, and shipping. Can't find it? Contact us.
What does "research use only" mean?
All products are laboratory reference standards supplied solely for in-vitro research. They are not for human or veterinary use, and they are not drugs, foods, dietary supplements, cosmetics, or medical devices. They have not been evaluated or approved by the FDA.
Who is allowed to purchase?
You must be at least 21 and have a verified research account. When you create it, you answer three short questions about your research affiliation and intended laboratory use, and your account is verified as soon as you submit them, so you can order right away. Your answers stay with your account, and your research-use attestation is also recorded with each order.
Is a Certificate of Analysis available?
Where a lot has been assayed, its third-party Certificate of Analysis is published against that lot number and states the analyses performed and their measured results. The COA Library lists published reports for currently listed products and is searchable by product name or lot number; each one can be downloaded before or after purchase. If a product you are looking at shows no certificate, we do not yet hold one for that lot.
Can you advise on how to prepare or use a product?
No. We do not provide preparation, measurement, handling, or application instructions, and we cannot answer questions about use in or on humans or animals. For specifications, see the product page and its Certificate of Analysis; for handling, consult the applicable safety data sheet and your institution's procedures.
How can I pay?
At checkout you choose a payment method (Venmo, Zelle, Cash App) and send the order total directly to us. After you place the order, email a screenshot of your payment to [email protected] as proof. Your order is reserved and ships once we confirm payment. No card is charged on the site.
How is my order shipped?
Shipping options, timing, and regions are described in our Shipping Policy. Orders ship in plain, unbranded packaging with carrier tracking, which becomes available from your account and the Track page once a label is created.
What is your return policy?
Because of the nature of the products, returns are limited. Please review our Refund & Returns Policy for the conditions and the return window.
