Reviews
Read it critically. A Trustpilot score measures whether parcels turn up and support replies, not whether the vial contains what the label says. A vendor can have hundreds of happy delivery reviews and still show you a borrowed or fake certificate; the two are unrelated. Also watch for a burst of near-identical 5-star reviews in a short window, the signature of bought reviews.

Is BioSupply UK legit? The questions people ask
Is BioSupply UK legit?
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.
Can I trust BioSupply UK, and is it a good supplier?
You cannot independently verify its testing today. Its Trustpilot score is 4.8 from 116 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.
Is BioSupply UK a scam?
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.
Does BioSupply UK publish a real, verifiable Certificate of Analysis?
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.
Which UK peptide sellers do publish a verifiable certificate of analysis?
Of the 448 active UK sellers The Peptide Watch audits, 38 publish a certificate of analysis you can verify in their own name on the independent laboratory's own website. Ranked by most recent certificate, they are Lab77Peptides, Peptology Labs, Biovanta, Camo Chem, Biohackpeptides and 33 others. This is a record of who publishes verifiable paperwork, not a recommendation.
