GHK-Cu Peptide: Benefits, Dosage, Results & Side Effects

What Is GHK-Cu Peptide?

GHK-Cu peptide (Glycyl-L-Histidyl-L-Lysine Copper) is one of the most researched copper-binding peptides used for anti-ageing, collagen repair, skin healing, and hair regrowth. It naturally exists in the human body, but levels drop significantly with age. Because of its ability to bind copper ions and activate regenerative pathways, GHK-Cu has become extremely popular in skincare, hair treatments, and peptide therapy.

Research shows that GHK-Cu can stimulate collagen, reduce inflammation, tighten skin, heal wounds, repair DNA damage, and activate dormant hair follicles. GHRP-6 + CJC: Benefits, Dosage, and Stack for Muscle Growth
