Plain-language guidance for evaluating lot records without medical, dosing, or human-use information.
01 · COA basics
How to read a Certificate of Analysis
Match the product name, labeled quantity, lot number, received and reported dates, testing laboratory, and stated analytical method. Results apply to the identified submitted sample—not every lot or future batch.
Identity addresses whether the detected material matches the named compound. Purity reports the proportion detected by the stated method. Net content is the measured amount in the submitted sample.
A lot number connects a labeled item to batch-specific records. Compare the lot on the material with the lot shown on its certificate before relying on the document.
A COA is not an approval, prescription, medical recommendation, dosing guide, or proof of suitability for human or animal use. Testing scope and methods should be read exactly as issued.
05 · Accounts
Research-account eligibility
Catalog access requires a verified email, age confirmation, organization or research affiliation, role, state, and research-use attestation. Submission does not guarantee approval or availability.
06 · Shipping
Understanding USPS status
Rate estimates are generated from package and destination details. Tracking becomes available only after an accepted request is shipped and a carrier tracking number exists.
07 · Supplier review
How to evaluate a research-material supplier
A documentation-first review considers business identity, lot-specific records, testing scope, labeling, access controls, and support practices before price or availability.
Research-use labeling identifies a restricted intended use. It is not approval, a clinical claim, or permission to use a material in humans or animals.
