Frequently asked questions
All FAQs →What does "research use only" mean?
Every product is a laboratory reference standard supplied solely for in-vitro research — not for human or veterinary use, and not a drug, food, supplement, cosmetic, or medical device.
Is a Certificate of Analysis included?
Yes. Every tested lot is matched to a third-party COA covering identity and purity. Browse and download them in the COA Library, before or after purchase.
How do I pay?
Choose a method at checkout, send the total directly, then email a screenshot as proof. Your order is reserved and ships once payment is confirmed. No card is charged on the site.
Who can purchase?
You must confirm you are at least 21 and a qualified researcher (or authorized to buy for a research institution). This is recorded with every order.
Analytical reference standards.
