Janoshik Labs publishes a public verification portal. Any test attributed to this lab can be looked up and confirmed directly with the lab — so this result doesn't rest on our review alone.
This certificate carries no lookup code.
This is a purity and identity analysis. Sterility, endotoxins, and heavy metals were not screened — a high purity figure says nothing about those.
