🔬 What is GHK-Cu?
GHK-Cu (Glycyl-L-Histidyl-L-Lysine Copper) is a naturally occurring copper peptide complex that plays a vital role in tissue repair, wound healing, and skin regeneration. It is a tripeptide (GHK) bound to a copper ion (Cu2+), which is essential for its biological activity.
GHK-Cu is found naturally in human plasma, saliva, and urine, and its levels decline with age. It has been extensively studied for its regenerative properties across multiple tissue types, including skin, bone, and connective tissue. GHK-Cu is available in pen and freeze-dried vial formulations for research purposes.
⚡ How GHK-Cu Works
GHK-Cu works through multiple mechanisms to promote tissue regeneration and repair:
Gene Expression
Promotes expression of BDNF, VEGF, and BMP-2 (angiogenic and osteogenic factors)
Anti-Inflammatory
Reduces inflammatory cytokines and oxidative stress
Tissue Regeneration
Stimulates collagen synthesis, elastin production, and wound healing
GHK-Cu also functions as a copper chaperone, where CCS and Atox1 translocate to the nucleus acting as transcription factors, enhancing the peptide's regenerative effects.
📋 Research Applications
Wound Healing
Accelerates wound closure and tissue regeneration
Skin Health
Promotes collagen and elastin production for skin regeneration
Bone Healing
Promotes osteogenesis and bone regeneration
Anti-Inflammatory
Demonstrates anti-inflammatory properties in various tissues
📊 Clinical Studies
Wound Healing Research
- GHK-Cu promotes wound closure and tissue regeneration through enhanced fibroblast proliferation
- Stimulates collagen synthesis and angiogenesis in wound healing models
- Demonstrates anti-inflammatory effects in wound healing
Skin & Connective Tissue
- Copper complex promotes expression of BDNF, VEGF, and BMP-2
- Enhances collagen and elastin production for skin health
- Supports connective tissue regeneration and repair
Mechanism of Action
- GHK-Cu activates copper chaperones CCS and Atox1
- These chaperones translocate to the nucleus acting as transcription factors
- Copper binding is essential for the peptide's biological activity
