This lab doesn't publish a public lookup, so we can't confirm the certificate against the lab's own record. The document was reviewed before publication, but it rests on our review alone.
What portal verification means →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 100.11 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.
