Buying research peptides in the UK

Suppliers appear here because they are based in the UK or state that they ship there. Prices are compared in GBP only, never converted from other currencies, so the figures reflect what buyers in the UK actually pay. Rules on buying, importing and possessing research peptides are set nationally, and the regulator in United Kingdom is the Medicines and Healthcare products Regulatory Agency (MHRA): our page on whether peptides are legal in the UK summarises them, with links to the sources.

To compare prices for one peptide in GBP, go straight to BPC-157, Retatrutide, Tirzepatide, Semaglutide, Tesamorelin, GHK-Cu, Ipamorelin or Sermorelin. Before ordering from a supplier you have not used, run through our checklist for spotting an unreliable supplier, and check whether it publishes independent test results. The best-rated and fastest delivery rankings cover every region.
