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.
Label 30 mg · Lab measured 35.41 mg
118% of label, basis not stated — shown as printed. Reconstituted with 2 mL, a 50-unit draw holds 8.9 mg using the measured mass, against 7.5 mg on the label — 18% more.
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.
