# Peptide Authority

> The UK & EU's definitive peptide education platform — evidence-based, editorially reviewed, and PubMed-cited.

## About

Peptide Authority is an independent educational platform providing comprehensive, research-backed information on bioactive peptides. We cover mechanisms of action, safety profiles, regulatory context, and research evidence for 64+ peptides used in regenerative medicine, anti-ageing, metabolic health, cognitive enhancement, and cosmetic applications.

All content is reviewed by our [Editorial Board](https://peptideauthority.co.uk/editorial-board) and includes clear [Medical Disclaimers](https://peptideauthority.co.uk/medical-disclaimer). We are an educational resource — not a healthcare provider or retailer.
