Good
UK-based WooCommerce shop selling Retatrutide (RT3) in single vials from 5mg to 60mg, with Janoshik verification links listed per batch in a public COA hub. The site also sells syringes, wipes and bacteriostatic water, separately and in starter kits.
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.
- Report #213016, listed by the shop for its 40mg vial, is a heavy-metals test rather than a purity test.
What we found in its favour
- Janoshik task links are published for each Retatrutide batch in a public COA hub, including historical batches.
- Free Royal Mail Tracked 24 on UK orders over £50; same-day dispatch before 4:30pm Mon–Fri.
- Single vials from 5mg to 60mg; 10mg vial £52.19 at the September sale price (regular £57.99).
- Registered company (Pyrox Labs Ltd, 17321280), linked to Companies House from the site.
What cost it points
- No card payment option is offered at checkout, only Fena pay-by-bank (store cart checked 30 September 2026), although the FAQ mentions cards and bank transfer.
- The 60mg product page links to an older Janoshik batch (RE600327) than the one marked current in the COA hub (RE60-0809).
- Returns only for damaged, defective or incorrect items reported within 3 days.
- Company incorporated in July 2026; no trading address is shown on the site.
- Sells syringes and needles and shows a dose-to-syringe-units calculator.
- Current prices reflect a September sale; regular prices are about 10% higher (e.g. 10mg £57.99).
- Several Janoshik task numbers in the COA hub (e.g. 213043, 213016, 196384) are also listed by Astra Labs and ExtolX as their own batches with the same RE batch codes; this suggests a shared supplier or shared reports (client field not checked, 30 September 2026).
