Glossary

Key terms, in plain language

A quick reference for the lab and cryptographic terms used on this page.

COA (Certificate of Analysis)
A signed document issued by a testing lab that lists what a specific batch was tested for and the results. CertikLabs publishes a tamper-evident, digitally signed COA for every verified batch.
Batch / Lot
A single production run of a product. Every vial in the same batch shares the same raw materials and process, so test results for one batch only apply to that batch — not to the next one.
SHA-256
A one-way cryptographic fingerprint. We hash each report with SHA-256 and publish the fingerprint on a public blockchain, so anyone can later confirm the report has not been altered.
HPLC (High-Performance Liquid Chromatography)
The lab method used to measure purity. The sample is separated into its individual components and the main peak's area is reported as a percentage — for peptides, ≥95% is the standard acceptance threshold.
LC-MS (Liquid Chromatography – Mass Spectrometry)
The lab method used to confirm identity. After separation, each component's exact molecular mass is measured and compared to the expected mass for the declared molecule.
On-chain anchor
The transaction on a public blockchain that records the SHA-256 fingerprint of a verification report. It proves when the result was sealed and that it has not been changed since.
