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.
- ⚠ 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

Responsible Practice assessment
Material concerns- · Direct, unhedged effect descriptions with no research qualifier.
- · Benefit-claim language observed on site: "synergistic effect on body weight reduction through increased energy expenditure, decreased food intake (GLP-3 product description); potent growth hormone (GH) releasing properties (Ipamorelin product description)"
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.
