One compound, four checks, one certificate.
A lyophilised peptide is stable as a powder, so quality is decided earlier: who synthesised it, who tested it, and whether the certificate belongs to that exact batch. We show that whole path openly.

Certificate of analysis
Every certificate is new. Never rewritten from an old batch.
A COA states the batch number, the analysis date, the method and the result. If the date is older than six months or the batch number does not match the vial, it is not a certificate - it is decoration.
