Independent CoA Every Batch

Every compound begins at source. Pureline Biolabs sources exclusively from GMP-certified and ISO-compliant manufacturers with full documentation, batch records, and chain of custody on every shipment.

Before any product reaches our cold store, it undergoes independent third-party analysis by Janoshik Analytical — HPLC purity testing and mass spectrometry identity verification — so you receive only what the label states, at the purity it claims.

All products are lyophilised, cold chain stored at 2–8°C and dispatched in insulated packaging with gel ice packs. Every vial carries a QR code linking directly to the live publicly accessible Certificate of Analysis for that specific batch.
