QSC Peptides UK qSC Peptides UK (qsc-uk.com, shop at qscpeptide.com) is an overseas grey-market operator (Qingdao Sigma Chemical) running a UK-domestic-shipping storefront, priced in USD on the parent site, crypto-only (BTC/USDT). Its product pages embed a Janoshik COA naming QSC as both Client and Manufacturer (e.g. task #85185), which is better than most, but the certificate is a static image with no working verify link, and the task number alone does not resolve on Janoshik's server, so we could not independently confirm it. Not a UK company.
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.
