GHK-Cu is a naturally occurring peptide composed of three amino acids that binds to copper. It occurs naturally in our blood and becomes particularly active during skin damage and tissue repair. As we age, GHK-Cu levels in the body decrease significantly. While young adults have an average plasma level of approximately 200 ng/ml, this decreases to approximately 80 ng/ml around the age of sixty.
How does GHK-Cu work?
Studies suggest that GHK-Cu can bind to copper and iron ions in the body. Laboratory studies have shown that the peptide can influence various cellular processes, including stimulation of cell growth and differentiation, supporting gene expression, regulation of inflammation, and supporting tissue repair.
GHK-Cu and skin aging
Studies suggest that the peptide may be involved in stimulating collagen synthesis, supporting the extracellular matrix, improving skin texture and elasticity, restoring the skin barrier, reducing inflammatory responses, and supporting hyperpigmentation and skin lesions.
Research on wound healing and tissue repair
Animal studies comparing GHK-Cu with standard treatments such as zinc oxide showed faster wound healing in the group treated with the peptide complex. An increase in new blood vessel formation (neovascularization) and a reduction in inflammatory cells were observed.
Antioxidant and anti-inflammatory properties
Research suggests that GHK may neutralize hydroxyl and peroxyl radicals, reduce oxidative stress, reduce inflammatory markers, and support cellular protective pathways such as Nrf2.
