Small UK shop focused on GLP-1-type peptides, selling retatrutide in 5mg vials singly or in six-packs, with tracked next-day delivery included. It names no company, and its product page includes dosing instructions.
Worth knowing (not scored)
- Publishes dosing, reconstitution or injection guidance
- Makes weight-loss claims about the product
- No company name or number shown on the site
What we found in its favour
- Tracked Royal Mail delivery included; orders before 16:00 on weekdays dispatched the same day
- A retatrutide certificate for batch RE414 is published as a PDF (99.16% HPLC purity)
- Six-pack brings the price down to £42 per 5mg vial
What cost it points
- Only 5mg vials are sold; a single vial costs £70
- The certificate is issued by the shop itself and names no testing laboratory, so it cannot be independently verified
- No company name, address, terms or returns policy found on the site
- The product page gives human dosing instructions and the site makes weight-loss claims
- Checkout offers bank transfer only, despite a 'Pay by Card' banner
