How to check a BTLabs report
BTLabs offers a public Finnrick certificate ID 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.
