A Certificate of Analysis (COA) is only useful if you can read it. Here is how to interpret a third-party report from labs such as Janoshik or Uzorak.

Purity (HPLC)

Reverse-phase HPLC reports the percentage of the target peptide. For research-grade material, look for ≥99%. The chromatogram should show one dominant, clean peak.

Identity / mass

Mass spectrometry confirms the compound is what the label claims. A purity figure without identity confirmation is incomplete.

Batch and date

The COA should name the exact batch you received and a recent test date — not a generic certificate reused across stock.

Verification

Reputable labs let you verify a report by ID on their own site. Browse every NOVA Labs certificate in the COA browser.
