GHK-Cu (Copper Peptide)
What does "Skin Regeneration / Anti-Aging Peptide" mean?
GHK-Cu is a naturally occurring copper complex of the tripeptide glycyl-L-histidyl-L-lysine. The copper(II) ion coordinates through three primary sites creating exceptional stability. It was discovered by Loren Pickart in 1973 at UC San Francisco while researching factors in human plasma that could rejuvenate aged liver tissue.
Explained Simply
Your body naturally makes a tiny molecule with copper attached that acts like a repair signal. When you are young, you have lots of it (about 200 ng/mL in blood), but by age 60 it drops to only 80 ng/mL. This copper-peptide tells your skin cells to heal wounds, make more collagen, and stay young. GHK-Cu can reset over 4,000 genes to work like they did when you were younger!
How It Works
GHK-Cu stimulates collagen synthesis up to 70% in human dermal fibroblasts. It enhances angiogenesis via VEGF and bFGF upregulation, elevates antioxidant enzymes (SOD, glutathione peroxidase), and increases mesenchymal stem cell intracellular copper by over 2,000%. The peptide induces epigenetic changes that reset age-related gene expression patterns to resemble youthful cells.
Research by Sex
Effects in Men
- •Research shows 64.5% wound area reduction in ischemic skin models

- •Enhanced tight junction proteins (ZO-1, occludin) for skin barrier
Key Terms Explained
Copper peptide
A peptide with copper(II) ion coordinated through nitrogen donors, creating a stable complex with log K ≈ 16.4
Gene modulation
GHK-Cu affects over 4,000 genes - 59% upregulated (including collagen, elastin) and 41% downregulated (inflammatory markers)
Angiogenesis
Formation of new blood vessels; GHK-Cu upregulates VEGF with significant increases (P = 0.047) at 24 hours
MSC enhancement
Mesenchymal stem cell copper levels increase over 2,000% with GHK-Cu treatment
Research Areas
- •Wound healing (64.5% improvement in animal models)
- •Anti-aging and collagen synthesis (70% increase)
- •Hair growth via VEGF and HGF upregulation
- •Anti-cancer (upregulates CASP3, CASP8, CASP10, TP73, PTEN)
- •Pulmonary fibrosis (inhibits EMT via Nrf2, NF-κB pathways)
- •Ulcerative colitis (reduces TNF-α, IL-6, IL-1β)
- •Stem cell enhancement (57 genes upregulated)
Published Studies

GHK-Cu (Copper Peptide)
GHK-Cu is a naturally occurring tripeptide-copper complex discovered by Loren Pickart in 1973. It modulates over 4,000 human genes and is found in human plasma, saliva, and urine. Plasma levels average ~200 ng/mL at age 20, declining to ~80 ng/mL by age 60.
Key Facts
- •Molecular formula: C14H24CuN6O4 (403.9 Da)
- •Modulates 4,000+ genes (59% up, 41% down)
- •Stimulates collagen synthesis up to 70%
- •Increases stem cell copper by 2,000%
- •Formation constant log K = 16.4
Mechanism of Action
GHK-Cu coordinates copper(II) through three nitrogen donors in square pyramidal geometry. It upregulates COL1A1, ELN, VEGF, bFGF while downregulating TNF and IL-6. Enhances angiogenesis, elevates SOD and glutathione peroxidase, and resets age-related gene expression to youthful patterns.
Research Applications
- Wound healing: 64.5% wound area reduction in studies
- Anti-aging: 32.8% wrinkle depth reduction (8 weeks)
- Hair growth: Outperformed 5% minoxidil in mouse studies
- Collagen: 70% increase (vs 50% vitamin C, 40% retinoic acid)
Safety Profile
Low acute toxicity below 1% topical. Stable copper complexation prevents free Cu2+ release. Mild localized irritation possible. Avoid with Wilson's disease. FDA Category 2 for 503A compounding (2023).
