PGNA Labs pGNA Labs ('cheapest research peptides in the UK') sells BPC-157, TB-500, Retatrutide, GHK-Cu and MOTS-c with free UK shipping over £50 and 'batch COAs available for download on every product page,' claiming third-party HPLC testing, but names no laboratory and shows no company details. A downloadable COA from an unnamed lab is not independently verifiable.
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.
