British-made research peptides.

Prime Peptide Labs is a Manchester-based laboratory supplier serving academic, industrial and independent research groups across the United Kingdom, Europe and beyond.

We were founded by peptide chemists frustrated by the inconsistency of overseas suppliers — long shipping times, missing certificates and questionable purity. Every product we sell is synthesised or sourced through vetted GMP partners, then re-tested in-house by HPLC and mass spectrometry before it reaches our shelves.

Our standards

• Minimum purity of 98% verified by reverse-phase HPLC
• Mass confirmation by ESI-MS on every batch
• Nitrogen-purged, −20 °C storage until dispatch
• Batch-traceable Certificate of Analysis with every order

Research use only

Our products are supplied strictly for in-vitro laboratory and research use. They are not medicines, are not licensed by the MHRA for human use, and must not be administered to humans or animals. By purchasing from us you confirm you are a qualified researcher over the age of 18 and that you will handle our products in accordance with your local regulations.
