OUR APPROACH
Research evaluation criteria
We compare listing information. We do not independently verify products, credentials, or research suitability.
Comparable quantities
Products are grouped by name and labeled quantity, with different vial sizes and pack counts kept separate.
Clear pricing
We show listed prices and available codes. Confirm currency, shipping, taxes, exclusions, and current availability with the supplier.
Evidence and limitations
Evaluate supplier documentation, test reports, methods, batch identifiers, and relevant legal requirements independently. A directory entry does not establish identity, purity, safety, or fitness for a project.
Corrections
Members can report inaccurate listings for review. Supplier order and price do not represent quality rankings.
