Certificates of Analysis
Every batch we release is independently HPLC-tested before it ships. Find the current purity result for each compound below, or request the full batch-specific Certificate of Analysis.
Reading a Certificate of Analysis
A Certificate of Analysis (COA) documents the independent laboratory testing performed on a specific manufacturing batch — including HPLC purity, identity confirmation, and any relevant physical or analytical parameters. It ties a result to a dated lot, not to the product line in general, so the batch code on your vial should always match the batch code on the certificate you're given.
Purity (HPLC)
The percentage of the sample identified as the target compound by high-performance liquid chromatography, run against a reference standard.
Identity confirmation
Mass spectrometry or equivalent analytical confirmation that the compound present matches the labelled peptide sequence.
Batch traceability
A dated lot number linking the certificate to the exact production run your vial was drawn from — not a generic specification sheet.
