How prices are checked

we compare our price daily against genuine, established UK suppliers only (not marketplaces or unverifiable listings) and guarantee the lowest UK price. If you find a lower like-for-like price from such a supplier, we match it. In our 10 October 2026 snapshot of 17 UK-facing retailers, the median list price for 50 mg was £23.99 (range £7.98 to £26.99); Sable listed it at £7.98. Method and seller types are explained on the pricing methodology page.

Documentation

Every lot has its own Certificate of Analysis and every vial carries a printed lot number, so the paperwork matches the vial. You can request the CoA for the lot you will receive before you order. A useful CoA names the lot, the test method (usually HPLC for purity and mass spectrometry for identity), the result and the date.

Ordering

we have operated since 2019, ship next-day across the UK, and take payment by Pay by Bank via Wallid. Research materials can't be returned, but anything faulty or damaged in transit is refunded or replaced.

Research use only

GHK-Cu is sold for in-vitro laboratory research. It is not a medicine, is not for human or animal use, and nothing here is advice on use.
