Every batch. Verified.

Each production run is sent to an independent UK laboratory for HPLC and mass-spectrometry analysis before it's released for sale. We publish the result — not just the claim.

Our Story

Built by researchers, for researchers.

Reagent House was founded in the UK on a simple frustration: too much of the research peptide market runs on marketing claims instead of paperwork. We set out to build the opposite — a supplier that treats a Certificate of Analysis as the product, not an afterthought.

Every compound we release is manufactured to research-grade specification, independently tested, and traceable to the batch it came from. No proprietary blends, no unverifiable "purity" percentages — just material you can cite with confidence.

  • Purity over hype. If a batch doesn't clear 99%, it doesn't ship.
  • Transparent sourcing. Every batch's COA is published directly on its product page.
  • Researcher-first support. Real answers from people who understand the chemistry.
