A record appears on file after our pipeline identifies the document as a certificate of analysis and matches its printed compound to a catalog peptide. The record cannot prove authenticity, chain of custody, sterility, product safety, or suitability for use.
Lab, lot, date, compound, and purity fields are transcribed from the document and can contain extraction errors. “Older record” means the reported test date is more than 18 months old.
