UK Buyer's Guide

GHK-Cu Purity and CoA UK

Both GHK-Cu vials, batches UKPL-377 and UKPL-458, were tested by Marfleet Analytical Services Ltd and reported as above 99% purity.

What the GHK-Cu certificates do and do not say

The reports give purity as a threshold, above 99%, rather than a decimal figure, and they do not include a measured copper content or a peptide content result. For a metal complex that is a real gap: the copper-to-peptide ratio is part of the product's identity. We state this so buyers know what the paperwork covers. The listed analysis date for both is 07/08/2026. Supplied for in-vitro laboratory research only, not for human or veterinary use.

Published research on GHK-Cu copper peptide analysis is indexed on PubMed.

Intended Use: Strictly for in-vitro laboratory research. Not for use in humans or animals. This product has not been evaluated by the MHRA or FDA.
