About Peptide Authority
An independent UK & EU peptide education publisher. We explain UK law, regulatory context, safety, evidence grading, and athlete risk. We are not a retailer, not a clinic, not a prescriber, and we do not provide dosing or sourcing guidance.
Our mission
Peptide Authority exists to make UK peptide regulation, evidence, and safety literacy easy to navigate. The peptide space is full of social-media claims, clinic advertising, counterfeit weight-loss pens, and confusion about what is and is not a licensed UK medicine. We summarise primary sources — MHRA, NICE, NHS, EMA, WADA, and peer-reviewed research — so a non-specialist can understand what is reliable, what is uncertain, and what is risky.
We exist to help people have better conversations with their GP, specialist, pharmacist, or anti-doping advisor — not to replace those professionals. See our editorial standards, evidence grading, and UK regulatory methodology.
What we do
- Explain UK law and regulatory context for peptides (MHRA, NICE, NHS, EMA, WADA).
- Summarise the evidence — and clearly mark what is human, animal, theoretical, or insufficient.
- Warn about counterfeit weight-loss pens and unregulated online sellers.
- Help readers ask better questions of doctors, pharmacists, and anti-doping advisors.
- Distinguish licensed medicines, prescription-only medicines, and unlicensed compounds.
- Publish corrections promptly when something is wrong or out of date.
What we do not do
- We do not sell peptides or ship medicines.
- We do not provide personalised dosing, injection, reconstitution, or cycling instructions.
- We do not rank suppliers, recommend grey-market vendors, or run a “best peptide shop” list.
- We do not provide medical, legal, or anti-doping advice.
- We do not run a clinic, prescribe, or diagnose.
- We do not present unlicensed peptides as treatments, cures, or repairs.

UK & EU focus
Most peptide content online is written for the US market. Our framing is specifically for the UK and EU:
- MHRA, EMA, and Human Medicines Regulations context for each compound.
- NICE technology appraisals and NHS access routes for licensed medicines.
- Prescription-only medicine framing (UK POM) where it applies.
- UK Anti-Doping (UKAD) and WADA reference for athletes.
Editorial standards
All content follows a documented review process designed to catch overclaims, outdated regulation, missing safety warnings, and citation gaps. Each page shows a last-reviewed date and a route to send a correction.

Editorial team
Peptide Authority content is reviewed by a documented in-house editorial process — evidence grading, source quality rules, regulatory methodology, corrections, and clear conflict-of-interest disclosure. Named contributors and the review scope each one covers are listed on our editorial board page; the underlying review framework they work against is documented in our editorial standards.
We are not a peptide retailer
We do not sell peptides. We do not run a clinic. We have one affiliate relationship — disclosed openly — with a single retailer that supplies research peptides; we do not rank vendors, recommend sourcing routes, or steer readers toward unregulated buying. The affiliate relationship is disclosed wherever it appears and is reviewed against our editorial firewall. Read the full statement on the We Are Not A Peptide Retailer page and the conflict of interest policy.
