Alternatives to BioSupply UK in the UK: sellers you can actually verify
BioSupply UK (biosupplyuk.com) does not publish a certificate of analysis you can verify in its own name. If that is why you are looking for an alternative, the UK sellers further down do, so you can check the testing yourself before you buy. The Peptide Watch takes no vendor money and links to no seller's shop.
Why BioSupply UK is on the watch list
BioSupply Group Ltd (Companies House 17152707) sells BPC-157, GHK-Cu, TB-500, Retatrutide and Melanotan at low prices and states 'independently tested for purity, we provide a certificate of analysis with all products,' but names no laboratory, so the certificate cannot be independently checked. Domain registered March 2026.

- Trustpilot: 4.4 from 25 reviews, which reflects delivery and service, not what is in the vial
