Our Process

How Every Lot Is Prepared

Controlled environments, documented production, and batch-specific verification from fill-finish through final release.

  1. 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.

  2. 02

    cGMP-Compliant Facility

    Production runs under current Good Manufacturing Practices — the validation, documentation, and traceability of precision pharmaceutical manufacturing.

  3. 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.
