How to check a Horizon Analytical report
Horizon Analytical offers a public Report Number lookup (the QR code opens the lab's search page). 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: 14 of 22
- Heavy metals reported: 0 of 22
