Disclaimer
This site is an educational reference, not medical advice. Compounds discussed here with no UK marketing authorisation and no other lawful UK use (for example as a food supplement or cosmetic ingredient) are not intended for human consumption, ingestion, injection, or therapeutic use of any kind. This describes UK status only; some compounds are registered or approved in other jurisdictions, as each profile states. Some compounds discussed here (semaglutide, liraglutide, oxytocin, desmopressin and argipressin) are authorised UK prescription-only medicines and should only be used as prescribed.
Scope
This site is an educational reference. Its content describes published research, mechanism of action, safety profiles as reported in the literature, and regulatory status. It does not constitute medical advice, treatment recommendation, or guidance for human use. Readers seeking medical advice should consult a qualified clinician.
UK regulatory position
Regulation 46(1) of the Human Medicines Regulations 2012 provides that a person may not sell or supply, or offer to sell or supply, an unauthorised medicinal product. Each peptide profile states what was found in the electronic medicines compendium (emc) on 17 October 2026; the emc is not a complete record of UK authorisations, so the MHRA Products database should also be checked. Whether a particular substance is a medicinal product is defined in regulation 2(1) of the Regulations.
None of the peptides profiled on this site appears by name in Schedule 2 to the Misuse of Drugs Act 1971, so none is a controlled drug as a named substance. That does not decide whether any particular sale, supply, possession or import is lawful: the Human Medicines Regulations 2012 and the Psychoactive Substances Act 2016 apply separately. See the UK peptide regulations guide for the provisions, each linked to the legislation.
Liability
Information on this site is provided as-is, without warranty of completeness or accuracy. The site authors accept no liability for any action taken on the basis of information presented here. Researchers using these compounds in laboratory work do so under their own professional and institutional responsibility.
External links
Links to external suppliers (PeptideBarn.co.uk, PeptideAuthority.co.uk) are provided on the profiles of compounds for which no UK marketing authorisation was found, as research-sourcing references. The site does not vouch for the quality, purity, or regulatory compliance of any specific commercial supplier. Researchers should perform their own due diligence — third-party purity testing, supplier credentialing, and documentation review — before placing any order.
Changes
The regulatory status of research peptides can change. While this site is kept reasonably current, readers should verify the current status of any specific compound with primary regulatory sources (MHRA, Home Office) before relying on the position stated here.
