Alternatives to Nilah Labs in the UK: sellers you can actually verify
Nilah Labs (nilahlabs.co.uk) 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 Nilah Labs is on the watch list
Nilah Labs (Nilah Ltd, Companies House 16924398, London) sells GLP-1 blends, GHK-Cu, BPC-157 and more, and unusually publishes the full chromatogram, stating testing is by 'a 3rd party UK lab under UKAS accreditation (ISO/IEC 17025)' with an average 99.1% purity. But it names no specific laboratory, so the accreditation claim cannot be checked. More transparent than most, but still not a verifiable own-name certificate from a named lab.

- Trustpilot: 4.0 from 3 reviews, which reflects delivery and service, not what is in the vial
