—— UK SUPPLY & TESTING

Research Peptides in the UK

Crown Peptides supplies research-grade peptides to laboratories, research organisations and independent researchers across the UK, Ireland and the EU. Every compound we stock is held in controlled storage in the UK and dispatched the same working day on orders placed before 2pm.

Each batch is tested twice before it reaches you: high performance liquid chromatography to confirm purity, typically 99% or higher, and mass spectrometry to confirm identity. The certificate for that batch is published on this site, and the QR code on every bottle opens it directly, with no account and no request form.

Our catalogue runs to more than forty research peptides and compounds, from widely studied ones such as BPC-157, TB-500 and GHK-Cu through to newer additions, alongside multi-vial bundles for longer studies and the lab supplies to go with them. All products are supplied strictly for laboratory research use and are not for human or veterinary use.
