The Ledger verdict
No. 21Computed from facts on the shop’s own pages — not a lab result.
Same-day dispatch, tracked UK delivery and public COAs, but payment is arranged after checkout and the pages disagree on the free-delivery threshold.
Ideal for UK labs and research buyers who want same-day dispatch and tracked delivery within the UK
