Tested Peptides publishes its own Janoshik certificate of analysis, naming Tested Peptides as the client, with its most recent certificate dated Jan 2026. Because Janoshik reports carry a unique code checkable on janoshik.com, the result can be independently verified.
See the full audit. This is the short answer; the full Tested Peptides dossier has the certificate check with a live verification link, the Companies House record, pricing against the market and the complete checklist.
On The Peptide Watch's independent audit, Tested Peptides (testedpeptides.co.uk) publishes its own verifiable Janoshik certificate of analysis that names Tested Peptides 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.
Its lab evidence is independently verifiable, which is the best signal a paper trail can give. Its Trustpilot score is 4.2 from 7 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.
Nothing in this audit indicates that. Tested Peptides 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'.
Yes. Its most recent own-name Janoshik certificate is dated Jan 2026 and can be verified on Janoshik's website by its unique code, so the purity result cannot be faked or edited.
