How to check a United Laboratories report

United Laboratories offers a public report number + verification 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.

  • Endotoxin reported: 13 of 13
  • Heavy metals reported: 13 of 13
  • Sterility reported: 13 of 13
