Certificate of Analysis — by compound
How we test
Each batch is assessed for HPLC purity (the share of the sample that is the target peptide) and mass-spectrometry identity (confirming the molecule is what it claims to be). Independent third-party verification (e.g., Janoshik) is being rolled out per lot. To request the COA for a specific lot, contact us.
