Comprehensive review of GHK-Cu's role in wound healing, skin repair, and anti-aging. Documents the peptide's ability to upregulate over 30 genes involved in tissue remodeling, collagen synthesis, and antioxidant defense. Establishes GHK-Cu as one of the most potent naturally occurring tissue repair signals.

Key Findings

GHK-Cu upregulates collagen, elastin, and glycosaminoglycan synthesis in skin fibroblasts

Activates over 30 genes involved in tissue remodeling and repair

Potent antioxidant effects via upregulation of superoxide dismutase and catalase

Promotes nerve outgrowth and has neuroprotective properties

Reduces expression of genes associated with cancer progression and metastasis

Methodology

Systematic review of in vitro, animal, and human clinical studies on GHK-Cu. Gene expression analysis via microarray data from multiple tissue types.

Limitations

Many findings from in vitro studies; clinical translation requires larger controlled trials. Topical bioavailability varies significantly by formulation.
