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.
- ⚠ No research-use-only disclaimer published anywhere on the site
- ⚠ No research-use disclaimer inside individual product listings
- ⚠ Publishes benefit claims next to products despite research-only framing
- ⚠ No UK trading entity could be found despite a thorough search, though the site presents as UK-based

Separate from Testing Transparency
Responsible Practice assessment
Material concerns- · No RUO disclaimer published anywhere on the site (mechanical fact) -- the specific quote may be a legitimate trial citation, but the RUO absence is the real trigger.
- · Benefit-claim language observed on site: "up to 24.2% body weight reduction in 48-week trials"
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.
