B12 × 24peptides.com — lab test, December 2025
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.

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

99% of label, basis not stated — shown as printed. Reconstituted with 2 mL, a 50-unit draw holds 2.5 mg using the measured mass, against 2.5 mg on the label — 1% less.
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.
