UK-only shop selling retatrutide (listed as 'Reta') in 10mg to 40mg vials, sent by Royal Mail. The site says batch COAs are published, but its COA archive page was empty when checked.
Worth knowing (not scored)
- Company named on the site could not be matched at Companies House
What we found in its favour
- Low listed prices: £21.50 for 10mg up to £65 for 40mg
- Ships from the UK by Royal Mail with tracking
- No dosing guidance, syringes or pens on the site
What cost it points
- No lab reports published: the COA / Lab Reports page said 'No COA files available yet', and the product page says COAs are available on request
- No company number or address shown; the named trading entity, Power Research, could not be matched to an active company on Companies House
- Checkout offers pay-by-bank only, although the terms list card and PayPal payments
- No Trustpilot profile found
- The retatrutide product photo carries a 'Dola AI' watermark
