BioSupply UK bioSupply Group Ltd (Companies House 17152707) sells BPC-157, GHK-Cu, TB-500, Retatrutide and Melanotan at low prices and states 'independently tested for purity, we provide a certificate of analysis with all products,' but names no laboratory, so the certificate cannot be independently checked. Domain registered March 2026.

BioSupply UK (biosupplyuk.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.
You cannot independently verify its testing today. Its Trustpilot score is 4.4 from 25 reviews, which reflects delivery and service, not whether a vial contains what the label says. A good delivery reputation is not the same as a verifiable certificate; the two are unrelated. Until BioSupply UK publishes an own-name certificate you can check on an independent lab's website, you are taking its quality on trust.
The Peptide Watch does not assert that. What is observable is the reason it sits on the watch list: no named lab, nothing to verify. Being unverifiable is a reason for caution, not proof of fraud.
Not one that can be independently verified in its own name. ⚠ 'CoA with all products' but no lab named. BioSupply UK says everything is independently tested with a CoA, but names no laboratory to check it against.
