Excellent
Trading name of ExtolX Limited, a Preston-registered company listing retatrutide in 10mg and 20mg vials with a Janoshik verification link on each product page; both sizes were out of stock on 30 September 2026.
Worth knowing (not scored)
- The 10mg lab report (#196384) names the manufacturer utherpeptide.com as the client; the 20mg report (#212480) was commissioned by ExtolX itself.
What we found in its favour
- Company name, number (17314659) and registered office shown on the site and matching Companies House.
- Janoshik verification links on both retatrutide product pages.
- Free Royal Mail Tracked 48 on every order; Tracked 24 £4.65.
- 14-day change-of-mind cancellation with no blanket exclusion for opened products.
- No dosing calculators, syringes or pens on the site.
What cost it points
- Both retatrutide sizes were out of stock on 30 September 2026.
- The 10mg Janoshik report (task 196384, batch RE10-0608) is also listed by Pyrox Labs as one of its own batches, so it may not be ExtolX's own test.
- No card payment; pay-by-bank or bank transfer only.
- Company incorporated on 2 July 2026, so trading history is short.
- Only 2 Trustpilot reviews (score 3.8, checked 30 September 2026).
