UK MARKET INTELLIGENCE

The Top 5 Grey Market Brands
in the UK — 2026

Britain’s unregulated GLP-1 and peptide market has moved from niche to mainstream visibility. There is no authoritative public estimate of annual UK grey-market sales, but the MHRA seized nearly £45m of illegally traded medicines in 2025, including more than 5,000 illegally traded GLP-1 products, and has since disrupted multiple illicit weight-loss manufacturing operations.

We’ve reviewed the current landscape, product breadth, brand visibility and market presence to take a closer look at five names shaping the space in 2026.
