The BioLongevity Labs Quality Standard

Every batch is documented before it ships.

Purity Verified by UHPLC-MS

Each batch is tested by ultra-high-performance liquid chromatography with mass spectrometry, confirming both purity and molecular weight against the expected value.

Endotoxin Tested to 0.05 EU/mL

MDx BioAnalytical Laboratory screens each batch against a 0.05 EU/mL threshold, with the result printed on the certificate.

Independent COAs for Every Lot

SafeCert, BioRegen and MDx tested. No batch ships without a lot-matched certificate of analysis. Every document is available before purchase, not on request.

USA Manufactured, Chain of Custody Documented

Synthesis, testing, and fulfillment happen domestically, with records tracking each lot from synthesis through release.
