How Every Lot Is Prepared
Controlled environments, documented production, and batch-specific verification from fill-finish through final release.
- 01
Filled & Finished in an ISO-5 Cleanroom
Every vial is filled under ISO-5 conditions — equivalent to EU GMP Grade A, the standard for sterile fill-finish. HEPA-filtered unidirectional airflow, positive room pressure, and gowned airlock entry hold the air to ≤ 3,520 particles (0.5 µm and larger) per m³, with continuous particle monitoring.
- 02
cGMP-Compliant Facility
Production runs under current Good Manufacturing Practices — the validation, documentation, and traceability of precision pharmaceutical manufacturing.
- 03
Tested & Verified
Every lot is third-party tested for identity, purity, potency, heavy metals, and endotoxins — with full Certificates of Analysis.
Facility and testing statements reflect documentation supplied for applicable production lots and manufacturing partners. Certificates of Analysis are organized by product and batch where available.
