A public COA library with reports from BioRegen, Bioviridian, and Janoshik Analytical. Certificates with a confirmed matching laboratory record receive provider verification; other documents remain vendor-hosted evidence.

Best for

Readers who want to check individual product and batch certificates against the issuing laboratory’s own records.

Watch-out

Coverage varies by product and batch. The reviewed reports focus on purity and identity, with some endotoxin results. Sterility and heavy-metals testing are not established where those panels are absent; check the exact report for the product you are evaluating.

Provider verification at BioRegen, Bioviridian, and Janoshik

The public library includes reports issued by BioRegen, Bioviridian, and Janoshik Analytical. Provider verification requires an exact matching laboratory record, including the document identity and client. Documents without that confirmation remain vendor-hosted evidence. Current product coverage, verification counts, and reported purity appear in the live evidence summary.
