Zelvix Labs supplies research peptides and reference compounds analyzed by Janoshik Analytical — an independent third-party laboratory. Every lot ships with its own lot-matched Certificate of Analysis.
We publish the whole certificate. Not the headline.
Every lot we stock is analyzed by Janoshik Analytical — an independent laboratory with no stake in the result — using reversed-phase HPLC for purity and mass spectrometry for identity. We publish that certificate in full, chromatogram included, for the exact lot number printed on your vial. No summary sheets. No numbers without the graph behind them.
From synthesis to your bench.
