Google Ads

ℹ️ Note: this seller also runs Google ads for research peptides, a category Google's own policies prohibit, visible in Google's Ads Transparency Centre (UK). Worth knowing, but it doesn't bear on the question that puts it on the independently-tested list: its certificates are its own and genuine.

Is Thoroughbredlabs legit? The questions people ask

Is Thoroughbredlabs legit?

On The Peptide Watch's independent audit, Thoroughbredlabs (thoroughbredlabs.co.uk) publishes its own verifiable Janoshik certificate of analysis that names Thoroughbredlabs 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 Thoroughbredlabs, and is it a good supplier?

Its lab evidence is independently verifiable, which is the best signal a paper trail can give. 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 Thoroughbredlabs a scam?

Nothing in this audit indicates that. Thoroughbredlabs 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 Thoroughbredlabs publish a real Certificate of Analysis?

Yes. Its most recent own-name Janoshik certificate is dated Sep 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. Thoroughbredlabs 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.
