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?
Credit and debit cards, Apple Pay and Google Pay at checkout. Payment is processed securely when you place the order and the order is confirmed immediately. Your card details are never stored by us.
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.
