Peptides UK 4U peptides UK 4U sells a wide range including GLP-1s (retatrutide, semaglutide, tirzepatide, cagrilintide) alongside classic research peptides, stamping 'Lab tested, 99%+ purity' and 'independent third-party HPLC testing on every batch.' It names no laboratory and publishes no certificate you can verify. It also shows no registered company, no VAT number and no trading address, and takes contact only through WhatsApp and email. An anonymous, WhatsApp-only seller with an unverifiable purity claim is exactly the profile buyers should be most careful with.
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.
