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.

Analytical reference standards,
nothing more, nothing implied.
Lonvera Labs supplies lyophilized research reference standards for laboratory research use only. Testing is done at an independent U.S. third-party lab, and certificates are tied to the lot.
