Why some details are redacted on our COAs

You may notice that certain information — such as the supplier name, laboratory client details, or order references — is blacked out on some certificates. This is standard practice in the research peptide industry and is done solely to protect the confidentiality of our supply chain. Revealing supplier identities would expose proprietary sourcing relationships that keep our pricing competitive and supply consistent.

The redactions do not affect the scientific validity of the results. The peptide name, dose, batch number, purity figure, analytical method, and Janoshik Analytical's independent certification remain fully visible and unaltered on every certificate.
