No UK trading entity found
We searched UK Companies House thoroughly (exact name, exact phrase, and plausible variants) and found no matching registration, despite this site presenting as UK-based. This is a Business Transparency finding and does not affect the Testing Transparency result shown above, which is scored on its own six signals only. It is not proof of wrongdoing, only that we could not confirm who operates this business: see methodology.

Responsible Practice assessment
Material concerns- · Retatrutide research page still quotes "mean weight reduction up to 17.5% at 24 weeks and 24.2% at 48 weeks" and refers readers to third-party Biovanta Research with discount code NEW15 -- verbatim match to the original finding, verified live 21 Aug 2026.
We assess what a brand publishes and makes available to customers, not its intentions. Full framework and what each status means: how we assess brands. Think this is wrong? Email hello@peptideclear.co.uk with evidence.
