freedomdiagnosticstesting.com 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.
Label 100 mg · Lab measured 99.65 mg
100% of label, basis not stated — shown as printed. Reconstituted with 2 mL, a 50-unit draw holds 25 mg on both the label figure and the measured one.
One vial from this lot was weighed by the laboratory, not yours. This page reports what the certificate says; it does not recommend a dose.
