About
Eli runs the lab-data side of the desk: COA reading, chromatogram interpretation, the Janoshik corpus, and the COA verifier tool. His background is analytical chemistry — twelve years in HPLC-MS method development at QC labs serving the supplements and pharmaceutical industries. He's the reason vialaudit asks specific questions about peak shape, integration windows, and signal-to-noise rather than just citing the purity percentage at the bottom of a report. If a vendor's COA uses a method that wouldn't pass an FDA inspection, Eli writes about it. Eli writes under a pen name. He still works in the analytical-chem world; a public byline on grey-market peptide commentary would be career-difficult. The pseudonymity is the price of getting the analysis at all.
