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 caps the CoA tier below green regardless of score. 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

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"
