UK Peptide Regulation Hub
A reader's guide to how UK regulation actually applies to peptide research, unapproved compounds, prescription-only medicines, and the lines that turn a 'research chemical' into a medicinal product. Educational only — not legal advice.
UK peptide law & the MHRA
High-level explanation of the medicinal-product concept and why claims and intended use matter more than labels.
Unlicensed medicines & 'specials'
What 'specials' are, why they exist, and why this is a clinician-led route — not a self-purchase route.
POM advertising rules
Why prescription-only medicines (including GLP-1 agonists) cannot be advertised to the public, and why we avoid promotional framing.
Research chemicals vs medicines
Intended use, claims, and the supply context determine whether a compound is regulated as a medicine — labels do not.
Borderline products
When does a peptide cross the line into being a medicinal product, and why is this ambiguous in practice?
Anti-doping & WADA
Why peptides are heavily scrutinised in elite sport. Athletes should seek qualified anti-doping advice — we do not.
Importation risks
Customs and regulatory uncertainty around peptide importation into the UK. We do not provide sourcing guidance.
