BioRegen 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. Enter the certificate number and validation key printed at the top of the certificate; no account is needed. Older endotoxin and pH reports print a report ID, which works as the number.
This certificate carries no lookup code.
Not on file for this certificate: sterility and heavy metals. A purity figure says nothing about those.

102% of label, basis not stated — shown as printed. Reconstituted with 2 mL, a 50-unit draw holds 15.3 mg using the measured mass, against 15 mg on the label — 2% 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.
