Are research peptides legal in the UK?

It depends on the compound. This site's legal fields are national. The UK is one of four countries we store, and we do not map it county by county. Approved peptide drugs such as semaglutide and tirzepatide are licensed and prescription only (MHRA, the UK drug regulator). GHK-Cu is allowed as a cosmetic ingredient, which is not the same as an injectable drug. Most research peptides, including BPC-157, TB-500, ipamorelin, CJC-1295, MOTS-c, KPV, and epitalon, are listed not licensed. PT-141 is listed not widely licensed. Sub-national UK detail is missing from this dataset. Compound pages: /legal.
