Our Standards
Four pillars of quality control ensure what's on the label matches what's in the vial — every time.
Liquid chromatography paired with mass spectrometry confirms identity and purity ≥99% on every batch.
Every batch ships with a downloadable Certificate of Analysis signed by an accredited third-party lab.
Lyophilized in sterile vials and shipped insulated to preserve molecular integrity in transit.
LAL endotoxin and sterility screening on every lot, recorded against batch numbers.
