British Peptide Labs british Peptide Labs ('shipped from London, UK hub', [email protected]) sells Retatrutide, Tirzepatide, GHK-Cu and MOTS-c with GBP pricing and UK next-day delivery, claiming 'independent third-party mass spectrometry', but names no specific laboratory.
The Peptide Watch benchmarks every vendor on the same compound, BPC-157, the most common research peptide, as £ per milligram, so prices are directly comparable across all providers. No public BPC-157 price feed was available for this vendor at audit.
