Pureline Biolabs Ltd · Company No. 17236739 · Registered in England & Wales · Not evaluated by the MHRA
Every batch independently verified by HPLC and mass spectrometry. Cold chain stored and dispatched from the UK. Minimum 99% purity guaranteed — documented, traceable, trusted.
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.
