Glycyl-L-Histidyl-L-Lysine
GHK is the parent tripeptide (Gly-His-Lys) found in human plasma. Distinct from GHK-Cu, which is GHK bound to copper — the non-copper form is used in some cosmetic and research contexts.
Modulates gene expression related to wound healing, collagen synthesis, and anti-inflammatory pathways. Copper chelation produces the more commonly studied GHK-Cu form.
Most research has focused on GHK-Cu; the plain tripeptide is less studied. Some cosmetic formulations use GHK rather than GHK-Cu for stability or formulation reasons.

Notes
Primarily a cosmetic peptide; bare GHK is less potent than GHK-Cu.
