Are peptides legal in the UK?

Research peptides are legal to purchase in the UK for in-vitro laboratory research purposes. They are not approved for human consumption.

Pure peptides refer to peptides that have been synthesised to a high level of purity, typically 98%+ as verified by HPLC testing. Purity is one of the most important factors when selecting a supplier for research. See our pure peptides UK guide for more on what to look for.

The original UK peptide price comparison site

PeptideSupermarket® is run by Ashcombe Vane OÜ, an independent company registered in Estonia. We launched the UK's first dedicated peptide price comparison site because researchers were spending hours checking dozens of supplier websites.

We don't sell peptides ourselves. No supplier owns or controls this site, and our comparisons are never influenced by commercial relationships.
