Plain-English guides for UK research buyers. The MHRA framework, reading a Certificate of Analysis, and understanding UK dispatch — in that order.
A complete map of where research peptides actually sit under UK law — the Human Medicines Regulations, the MHRA's classification boundary, and why "unregulated" is the wrong word for what is really an unlicensed category with its own grey areas.
Read the guideHow semaglutide's UK regulatory status shapes the wide price variation seen across listings, and the Certificate of Analysis checks a research buyer should run before trusting any batch.
Read the guideWhat a UK seller of research peptides is legally required to have in place — product classification, labelling, batch documentation and dispatch rules — before listing a single vial, and where sellers most often fall short.
Read the guideThe direct answer on peptides UK: most research peptides are not MHRA-licensed medicines, legality depends on the specific compound, and an independent Certificate of Analysis is the standard that actually protects a buyer.
Read the guideWhat the Medicines and Healthcare products Regulatory Agency governs, where research peptides sit within that framework, and what it means in practice for a UK buyer verifying a batch.
Read the guideA close reading of every field on a Certificate of Analysis — HPLC chromatograms, LC-MS identity, Karl Fischer water content, endotoxin limits — interpreted through the expectations a UK research buyer should hold.
Read the guideHow domestic dispatch differs from international import for research peptides, what provenance and batch documentation to look for, and why the paper trail from lab to door matters as much as the COA itself.
Read the guideInjectable Wegovy is MHRA-authorised as a prescription-only medicine. Oral Wegovy received MHRA marketing authorisation on 11 June 2026, though NHS access is pending NICE review. Unlicensed forms hold no marketing authorisation, and the MHRA seized almost 20 million doses of illegally traded medicines in 2025.
Read the guideWhat tirzepatide is as a research peptide, the five-point documentation set a batch should carry — lot number, HPLC chromatogram, mass-spectrometry identity, independent lab, UK dispatch — and the listing red flags worth treating as a reason to pause.
Read the guideWhat research-grade semaglutide is, how its documentation and oversight differ from a prescription medicine's, and the batch paperwork — Certificate of Analysis, chromatogram, identity check, independent lab — to verify before you buy.
Read the guideEvery guide on The Standards Register is written to one principle: teach the standard, not the sale. We explain what an independent Certificate of Analysis must contain, how the UK regulatory environment frames research compounds, and what questions a diligent buyer ought to ask before any transaction — without directing you to any commercial outcome. Sources are limited to neutral authorities: gov.uk, the MHRA's published guidance, ISO standards, and peer-reviewed analytical chemistry references.
