Description and reported dosing

What is GHK-Cu?

The tripeptide glycyl-histidyl-lysine bound to a copper ion. It occurs naturally in human plasma and its level falls with age, which is where the interest in it for skin, hair and wound healing comes from.

This is the rare case in the catalogue where the topical form has a regulatory standing and the injectable one does not: copper peptides are permitted as a cosmetic ingredient, while injected GHK-Cu has been approved by no regulator.
