◇ The Peptide Watch, independent vendor audit

Is ROK Chem legit? An independent review

rokchem.co.uk · audited 4 October 2026
🚩 ROK Chem is on the watch list: its certificate can't be verified in its own name, one of 412 of 450 UK sellers that fail this check.

ROK Chem ⚠ Sells a raw research-grade GHK-Cu peptide powder alongside skincare, states "developed, formulated and produced in the UK," free UK shipping. Only a bare "99.9% purity" claim, no CoA or testing lab named. Independently confirmed on Companies House: the disclosed entity "ROK CHEMICAL SUPPLIES LIMITED" (13782325) was Dissolved on 28 July 2026, yet the storefront is live and still taking orders as of 6 September 2026: a registered-company-dissolved-but-still-trading pattern, a higher-risk signal than a simple thin-evidence watch listing.

Which UK sellers do pass this check?

Of the 450 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.

Is ROK Chem legit? The questions people ask

Is ROK Chem legit?

ROK Chem (rokchem.co.uk) 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 ROK Chem, and is it a good supplier?

You cannot independently verify its testing today. Its Trustpilot score is 4.3 from 62 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 ROK Chem publishes an own-name certificate you can check on an independent lab's website, you are taking its quality on trust.

Is ROK Chem a scam?

The Peptide Watch does not assert that. What is observable is the reason it sits on the watch list: company dissolved, still trading. Being unverifiable is a reason for caution, not proof of fraud.

Does ROK Chem publish a real, verifiable Certificate of Analysis?

Not one that can be independently verified in its own name. ⚠ Sells a raw research-grade GHK-Cu peptide powder alongside skincare, states "developed, formulated and produced in the UK," free UK shipping. Only a bare "99.9% purity" claim, no CoA or testing lab named.

Which UK peptide sellers do publish a verifiable certificate of analysis?

Of the 450 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.
