1. They publish the actual lab report — not a purity number
Ask to see the Certificate of Analysis before you order. A number typed onto a product page is a claim; a PDF from a named laboratory, showing the chromatogram and the batch it belongs to, is evidence. If the report is cropped, has the lab name removed, or is the same file across several different products, treat that as a red flag.
Every batch we sell is HPLC-tested by Janoshik Analytical, an independent laboratory in Europe, and we publish the full report — chromatogram included — rather than a summary figure. Recent batches have consistently exceeded 94% purity, and each batch COA carries its own exact number.
