Excellent
UK shop operated by Astra Scientific Ltd selling retatrutide in a 10mg vial, with a public COA hub that links each batch to its Janoshik verification record.
Worth knowing (not scored)
- Publishes dosing, reconstitution or injection guidance
- Supplies needles or syringes
- Most published lab reports name the manufacturer utherpeptide.com as the client, not the shop; other shops publish the same reports for the same batches.
What we found in its favour
- COA hub lists Janoshik verification links for every retatrutide batch and keeps archived batches (current 10mg batch RE10-0718, task #213043).
- Company Astra Scientific Ltd (17113237) named in site metadata, with an address matching Companies House.
- Free Royal Mail Tracked 24 over £50; £4–£5 below that.
- Trustpilot score 4.7 from 200 reviews (checked 30 September 2026).
- Autumn offer: buy two Retatrutide 10mg vials and a third is added free.
What cost it points
- Only a 10mg retatrutide vial is on sale.
- Payment by Fena pay-by-bank only; no card option at checkout.
- Several Janoshik task numbers in the hub (e.g. #213043, #196384) also appear on other UK shops' COA pages, such as Pyrox Labs, which suggests a shared supplier; the client name on the reports could not be checked because Janoshik's site blocked access.
- Returns only for incorrect or damaged items reported within 48 hours.
- Sells insulin syringes and has a calculator giving insulin-syringe units.
