What we found
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.

Questions people ask about QSC Peptides UK
Is QSC Peptides UK legit?
QSC Peptides UK (qsc-uk.com) is on The Peptide Watch's watch list. It does not publish a certificate of analysis that can be independently verified in its own name, so its quality claims rest on trust rather than checkable evidence. That is not proof of a scam; it means the evidence does not check out.
Does QSC Peptides UK publish a real, verifiable Certificate of Analysis?
Not one that can be independently verified in its own name. ⚠ Overseas grey-market operator; own-name Janoshik COA shown as a non-verifiable image. QSC (Qingdao Sigma Chemical) shows a Client-QSC Janoshik image on product pages, but it does not verify on Janoshik's server as shown, and it is a crypto-only overseas operator with a UK-domestic warehouse.
How do I check QSC Peptides UK's certificate myself?
Find the certificate on qsc-uk.com and read four things: an independent laboratory is named; the client field names QSC Peptides UK, not a supplier; the compound line names the peptide you are buying, not only a batch code; and the report opens on the laboratory's own website from its task number and key (verify.janoshik.com for Janoshik). Then compare the batch number on the report with the one on your vial. The free COA Checker on this site runs the first three checks on a photo of the certificate.
