UK Research-Peptide Supplier
Research Peptides UK
Lyophilised reference standards for in-vitro laboratory research — ≥99% HPLC purity, batch Certificate of Analysis, dispatched same-day from our UK laboratory.
Research-only compliance
All peptides supplied by Professor Peptide are sold as lyophilised reference standards for in-vitro laboratory research only. They are not medicines, not authorised by the MHRA for human or veterinary administration, and must not be administered to humans or animals or resold for that purpose.
The compounds we list are not controlled under the UK Misuse of Drugs Act 1971 and are legal to purchase in the UK for documented laboratory research. Buyers confirm research-only intent at checkout, and every order ships with a research-use disclaimer on the vial label and packing slip.
For the full regulatory picture — MHRA position, customs handling, and researcher responsibilities — read our UK Peptides Legal Guide.

Universities, contract research labs, independent researchers and credentialled investigators purchasing reference compounds for documented in-vitro research. Buyers confirm research-only intent at checkout.
Do you provide a Certificate of Analysis?+
Yes — every batch ships with a Certificate of Analysis (HPLC chromatogram, mass-spec confirmation, water content, endotoxin where applicable). The full CoA library is public; you can verify any batch before ordering.
Where do you dispatch from?+
All orders ship from our UK fulfilment laboratory. Orders placed before 2 pm UK time on a working day are dispatched same-day via tracked courier. UK shipping is free.
