Is RETA UK legit? An independent review
RETA UK publishes a page of Janoshik certificates for its GLP-1 range and invites you to verify them at janoshik.com/verify. We did: one example (Tirzepatide 30mg, batch EGB-0526-TR30, task #148589) is a genuine Janoshik report that verifies on Janoshik's own server. But the client named on every certificate is 'EGB', and every batch code begins 'EGB-', so these are the wholesale supplier's blind-test certificates, not RETA UK's own. A genuine supplier certificate proves the supplier submitted a good vial once; it does not prove the stock this reseller ships you is the same. Add the placeholder registered name 'TEST TRADER LTD' (Companies House 17202698) and unusually low pricing, and this is a dropshipper of EGB stock, not an own-name tested seller.

Pricing vs the market, benchmarked on BPC-157
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.
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 RETA UK legit? The questions people ask
Is RETA UK legit?
RETA UK (reta-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.
Can I trust RETA UK, and is it a good supplier?
You cannot independently verify its testing today. Its Trustpilot score is 3.8 from 19 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 RETA UK publishes an own-name certificate you can check on an independent lab's website, you are taking its quality on trust.
Is RETA UK a scam?
The Peptide Watch does not assert that. What is observable is the reason it sits on the watch list: shows a supplier's certificate, not its own. Being unverifiable is a reason for caution, not proof of fraud.
Does RETA UK publish a real, verifiable Certificate of Analysis?
Not one that can be independently verified in its own name. ⚠ Real certificates, wrong name. RETA UK shows a full table of genuine Janoshik certificates, but every one names its wholesale supplier 'EGB' as the client, not RETA UK, so they prove EGB's batch was tested, not that this reseller's specific stock matches.
