Correction · Oct 10, 2026
We marked this certificate as disappeared on Sep 9, 2026 and again on Sep 19, 2026. That was our error: Bluum Peptides still listed this report (12554), linking the same BioRegen document, on Sep 9, 2026 and on Sep 19, 2026; a gap in our own review dropped it. It is listed as current again.

PB
A COA is evidence, not a blanket safety guarantee. It describes the submitted sample and the panels reported in this document. It does not independently establish chain of custody, current inventory identity, or suitability for human use.
