- Company incorporated on 23 September 2026, so trading history under this entity is very short.
- No change-of-mind returns; faults are resolved by replacement or store credit at the shop's discretion.
- Payment information is inconsistent: the cart shows Wallid pay-by-bank while the terms mention Visa and Mastercard.
- Retatrutide is listed under an abbreviated name (MM-RT3) and only in 10mg and 20mg.
