This is a purity and identity analysis. Sterility, endotoxins, and heavy metals were not screened — a high purity figure says nothing about those.

About this test

What’s in the vial

Label 10 mg · Lab measured 11 mg

110% of label, basis not stated — shown as printed. Reconstituted with 2 mL, a 50-unit draw holds 2.8 mg using the measured mass, against 2.5 mg on the label — 10% 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.
