How to check a Janoshik report

Janoshik offers a public task ID / QR code lookup. Enter the code printed on the seller's certificate on the lab's site and compare the lab's copy with the seller's: compound, lot, date, purity and amount should all match. Reports that print a usable lookup code earn full lab credibility points.

What these certificates report

  • Quantity measured: 69 of 71
  • Endotoxin reported: 3 of 71
  • Heavy metals reported: 0 of 71
  • Sterility reported: 0 of 71

Which tests appear depends on what each vendor ordered, not only on the lab. A panel a certificate doesn't mention counts as not reported, never as a pass or a fail.
