Pureline Biolabs Ltd was established to address a clear gap in the UK research peptide market. Too many suppliers offer unverified compounds with fabricated certificates, inconsistent quality and no cold chain infrastructure.
We built Pureline Biolabs around three non-negotiable principles — independent verification of every batch, medical grade cold chain storage from receipt to dispatch, and complete transparency about who we are and where our compounds come from.
Every vial we supply carries a QR code linking directly to its live publicly accessible Certificate of Analysis from Janoshik Analytical. Not a PDF we created. Not a certificate from the manufacturer. An independent uneditable verification report that any researcher can access instantly.
We never rely on manufacturer certificates. Every batch is independently verified by Janoshik Analytical before a single vial is dispatched.
From receipt to your door our compounds never leave the cold chain. Medical grade storage, continuous monitoring and temperature controlled dispatch on every order.
We are a registered UK company with nothing to hide. Our company number, registered address and independent test results are publicly available on every order.
All products supplied by Pureline Biolabs Ltd are intended solely for in vitro laboratory research purposes. They are not medicines, not approved for human or veterinary use, and not for human consumption. By purchasing you confirm you are 18+ and that all products will be used only in a suitable laboratory research context.
Every compound independently tested. Cold chain stored. Dispatched next day across the UK.
