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

Re-checked on a rolling basis, not a fixed monthly cycle; see the last-verified date above. See methodology for how this is scored.

Responsible Practice assessment
Material concerns- · Direct, unhedged property claims ('Renowned for its healing and protective properties') plus named medical conditions (bone deterioration, ulcers) with zero research qualifier.
- · Benefit-claim language observed on site: "Renowned for its healing and protective properties / Offers a variety of gastrointestinal benefits / Aids in addressing conditions like bone deterioration, joint pain, intestinal damage, and ulcers / Supports tissue repair and reduces inflammation in muscles, tendons, ligaments / May activate a network of activities through peptidergic defense systems (BPC-157 product page)"
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.
