Regenlabs shows a genuine Janoshik report to look legitimate, but the certificates on display name a rotating cast of unrelated companies as the client, not Regenlabs. In other words it has never paid to test its own stock; it has taken a certificate that proves a sample from its supplier's own line, and presents it as proof of what's in the vial it ships. The buyer is shown real-looking science that is, for their purposes, meaningless, there is no link between that certificate and the product they receive. Aggravating: recycles copy/templates shared with other 'brands'.
See the full audit. This is the short answer; the full Regenlabs dossier has the certificate check with a live verification link, the Companies House record, pricing against the market and the complete checklist.
Regenlabs (regenlabs.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.
You cannot independently verify its testing today. Its Trustpilot score is 4.5 from 16 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 Regenlabs publishes an own-name certificate you can check on an independent lab's website, you are taking its quality on trust.
The Peptide Watch does not assert that. What is observable is the reason it sits on the watch list: passing off someone else's certificate. Being unverifiable is a reason for caution, not proof of fraud.
Not one that can be independently verified in its own name. The Janoshik certificate is real, but the client on it is dozens of different companies, NOT them. They've never tested their own stock; they're displaying someone else's certificate, which proves nothing about the vial
