Reviews

3.9 ★★★★☆ · 5 reviews on Trustpilot

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 Reta24 legit? The questions people ask

Is Reta24 legit?

On The Peptide Watch's independent audit, Reta24 (reta24.co.uk) publishes its own verifiable Janoshik certificate of analysis that names Reta24 itself as the client, so its testing can be checked on Janoshik's own website. That is the strongest evidence standard we track. It confirms the credibility of the seller's evidence, not any individual vial you receive.

Can I trust Reta24, and is it a good supplier?

Its lab evidence is independently verifiable, which is the best signal a paper trail can give. Its Trustpilot score is 3.9 from 5 reviews, which reflects delivery and service, not whether a vial contains what the label says. Even a genuine certificate proves a sample was tested once, not that your specific batch matches it, so weigh it alongside consistent results over time.

Is Reta24 a scam?

Nothing in this audit indicates that. Reta24 shows a verifiable own-name Janoshik certificate, the opposite of the borrowed or self-made certificates the watch list flags. Judge it on that checkable evidence rather than the word 'scam'.

Does Reta24 publish a real Certificate of Analysis?

Yes. Its most recent own-name Janoshik certificate is dated May 2026 and can be verified on Janoshik's website by its unique code, so the purity result cannot be faked or edited.

The bottom line. Reta24 earns a place on the independently-tested list because it pays an independent lab (Janoshik) to test its own stock in its own name, and lets you verify it. That is the standard.
