PeptideLabUK is a UK-based vendor that serves both retail and bulk buyers, with a mid-sized catalogue and prices listed for nearly all products. Testing is vendor-hosted rather than through third-party labs like Janoshik — one COA shows 98% purity, but coverage across the catalogue is minimal. The site has not yet captured community feedback on product quality, shipping, or service, so buyer experience and vendor reliability remain largely undocumented.

Anecdotal signals
Testing coverage
We hold lab certificates for this vendor, but none of them correspond to a product currently in their catalogue — so we cannot confirm what is in any vial you could actually buy. Testing scores zero until that mapping exists. This one is on us as much as them.
