Conditions of supply
What every account and every listing on this site is bound by.
Verified accounts
Catalog pricing and ordering require an account with a completed research-use attestation and a stated institution or laboratory address.
In vitro supply only
Materials are supplied as analytical reference materials for in vitro laboratory study. Nothing on this site describes an application in humans or animals.
No claims, only data
Listings carry identity, assay, method, fill weight and lot. We publish what was measured and nothing else: no categories, uses or outcomes.
Frequently asked questions
No. All materials are supplied strictly for in vitro laboratory research. They are not drugs, foods, cosmetics or supplements, and are not for human or veterinary use.
Each product page lists its current lot: the certificate for released lots, and full disclosure (lab, status, purity and date) for held lots.
An accredited independent laboratory, named on each certificate.
Lyophilized and shipped with tracking on every order.
