GHK-Cu (Copper Peptide) is a naturally occurring tripeptide studied in human research for its role in tissue repair, cellular signaling, and antioxidant regulation. Clinical studies have explored its potential to support collagen production, wound healing, and skin health under controlled conditions. Research has also investigated GHK-Cu’s effects on inflammation modulation, cellular regeneration, and extracellular matrix maintenance. Human studies suggest it may help preserve tissue integrity and promote overall cellular resilience. Across published research, GHK-Cu has been widely used as a tool for studying regenerative pathways, antioxidant activity, and tissue health. Research Use Only. Not for Human or Veterinarian Use.
