About

Peptyx is a UK-based supplier of research-grade peptide compounds. We focus on a small, deliberate catalogue of well-characterised compounds, manufactured to laboratory standards and dispatched under cold chain to research institutions, contract research organisations, and independent laboratories.

How we work
We don't sell forty compounds badly. We sell two compounds with the documentation, packaging, and consistency a lab actually needs.

Verification — HPLC and Mass Spectrometry on every batch. Identity, purity, and counter-ion content documented.

Traceability — Every vial carries a lot number that correlates to its synthesis record and analytical certificate.

Logistics — Cold-chain packaging where required. Tamper-evident seals. Tracked next-day UK shipping in unbranded outers.

Compliance — We supply research compounds for laboratory use only. We do not provide dosing guidance, medical advice, or veterinary instruction.

A note on what these compounds are
The peptides we supply are biological reagents. They have been studied in scientific literature, sometimes for decades, sometimes for only a few years. The research is broad and ongoing — and in every case, studies referenced on this site were performed by third parties.

None of the compounds in our catalogue are approved as medicines in the United Kingdom. None are intended for human or veterinary administration. Our descriptions reference published research only — they are not claims, recommendations, or endorsements.
