Unvalidated means we could not verify it yet. It is a statement about our evidence, not an accusation.","verdict":"Its domain was registered in February 2026 (less than a year old); a matching active UK company is on the Companies House register (STERLING PEPTIDES LTD, 17078386); 3 of 8 transparency signals were found on its own published pages. With no independent lab results or verified community reviews yet, Litmus publishes these public-record facts but does not yet assign an overall trust score.","evidence":{"tier1":{"title":"Independent verification","sub":"Hard-to-fake records we checked at the source — registers, the ICANN domain record, independent lab verification, regulator actions.","tag":"Tier 1 · high weight","rows":[{"signal":"Domain age","finding":"Registered 26 Feb 2026 — 6 months ago, via Tucows Inc t/a Tucows. Under a year old — a common new-seller caution.","howWeChecked":"Domains under 12 months old are a new-seller caution. An older registration is context only because domains can change owners. The date comes from public ICANN RDAP.","tone":"warn","sources":[{"href":"https://rdap.org/domain/sterlingpeptides.co.uk","label":"ICANN RDAP record"}]},{"signal":"Company register","finding":"Matches STERLING PEPTIDES LTD (company 17078386) on the UK Companies House register — active, incorporated 9 Mar 2026.","howWeChecked":"An exact, active match on a public company register is a hard-to-fake positive.

Lists 2 investigational drugs with no approved formulation (Retatrutide, Cagrilintide).","howWeChecked":"We require a dated seller-catalogue receipt and an official product-status source. An ingredient name alone blocks a verified human-use route, but does not establish prescription bypass, intended human use or seller misconduct.","tone":"warn","sources":[{"href":"https://sterlingpeptides.co.uk/","label":"Seller catalogue"},{"href":"/compounds/tirzepatide","label":"Tirzepatide · product status"},{"href":"/compounds/retatrutide","label":"Retatrutide · product status"},{"href":"/compounds/cagrilintide","label":"Cagrilintide · product status"}]},{"signal":"Legal compliance","finding":"Not a verified human-use route. The dated research catalogue used 1 ingredient name (Tirzepatide) associated with prescription or regulator-warned products.
