Excellent
UK-dispatched shop selling retatrutide as 'Reta' in 10mg, 20mg and 30mg lyophilised vials, with a PeptideVerify HPLC and LC-MS certificate for batch BSUK003 linked from the product page.
Worth knowing (not scored)
- Company named on the site could not be matched at Companies House
What we found in its favour
- Retatrutide certificate (HPLC purity 99.0%, LC-MS identity confirmed) linked from the product page, with a certificate ID that resolves on PeptideVerify's verification service.
- Royal Mail tracked delivery from £2.99; same-day dispatch before 3pm on weekdays.
- Card payment logos (Visa, Mastercard) shown on the site.
- Trustpilot score 4.8 from 124 reviews (checked 30 September 2026).
- Multi-unit discounts of 10% for two and 15% for three vials.
What cost it points
- The certificate is not dosage-specific and states no measured content in mg; the laboratory partner behind PeptideVerify is not named.
- Only one retatrutide batch report found for three vial sizes.
- Company number and address are not shown on the site, so the named 'BioSupply UK Ltd' could not be matched to a Companies House record.
- No change-of-mind returns; all sales are final.
- Ships to UK addresses only.
