GHK
aka Glycyl-L-Histidyl-L-Lysine
Healing & Recovery
Mechanism
GHK is the parent tripeptide Gly-His-Lys, originally isolated from human plasma by Loren Pickart (1973) as an activity that caused aged hepatocytes to synthesize proteins like younger tissue. It is DISTINCT from GHK-Cu, the 1:1 copper(II) complex tracked as a separate entry — but GHK binds copper readily in vivo, so in physiological environments the bare peptide rapidly associates with available Cu(II). Not FDA-approved for any indication; used in cosmetic and research contexts only.
