About GHK-Cu
GHK-Cu (glycyl-L-histidyl-L-lysine:copper) is a naturally occurring copper tripeptide found in human plasma, saliva, and urine. It was first identified in human plasma in 1973 by Dr. Loren Pickart. Levels decline significantly with age — from approximately 200 ng/mL at age 20 to around 80 ng/mL by age 60. It affects over 4,000 genes, promoting tissue remodeling, anti-inflammatory responses, and antioxidant defense.

Key Benefits
Skin Regeneration & Anti-Aging
GHK-Cu stimulates collagen and elastin synthesis, increases fibroblast proliferation, and promotes glycosaminoglycan production. It improves skin firmness, reduces fine lines, and enhances overall skin quality.
Wound Healing & Tissue Repair
GHK-Cu accelerates wound contraction, promotes angiogenesis, and enhances nerve outgrowth. It attracts immune cells and fibroblasts to wound sites for faster repair.
Hair Growth & Follicle Health
GHK-Cu increases hair follicle size, stimulates hair growth, and extends the anagen (growth) phase. It helps counteract the effects of DHT on hair follicles.
Anti-Inflammatory & Antioxidant
The copper peptide complex modulates inflammatory cytokines, reduces oxidative damage, and supports the body's natural antioxidant defense systems including superoxide dismutase (SOD).
Gene Expression & Longevity
GHK-Cu resets gene expression of aging cells toward a healthier state, affecting over 4,000 genes involved in tissue remodeling, antioxidant defense, and DNA repair.
How GHK-Cu Works
GHK-Cu works through multiple mechanisms. The copper ion acts as a cofactor for enzymes involved in collagen cross-linking (lysyl oxidase), antioxidant defense (superoxide dismutase), and skin remodeling (matrix metalloproteinases). The tripeptide itself serves as a signaling molecule that modulates gene expression.
GHK-Cu resets the gene expression pattern of aging cells toward a healthier state. It upregulates genes involved in extracellular matrix production (collagen, elastin, decorin) while downregulating inflammatory and tissue-destructive genes.
The peptide also stimulates angiogenesis and nerve outgrowth, attracts immune cells to damaged areas, and suppresses genes associated with metastasis.
Frequently Asked Questions
What is GHK-Cu?
GHK-Cu (glycyl-L-histidyl-L-lysine:copper) is a naturally occurring copper tripeptide found in human plasma, saliva, and urine. Levels decline significantly with age — from ~200 ng/mL at age 20 to ~80 ng/mL by age 60.
How does oral GHK-Cu compare to topical or injectable?
Oral GHK-Cu provides systemic exposure after absorption through the GI tract. Topical GHK-Cu targets skin directly. Injectable forms offer the most direct bioavailability. Oral capsules are the most convenient option for daily use.
Is the copper in GHK-Cu safe?
The copper in GHK-Cu is chelated to the peptide and delivered in microgram quantities — far below the tolerable upper intake level for copper (10mg/day for adults). The chelated form also ensures controlled release.
Can GHK-Cu be taken with other peptides?
GHK-Cu is commonly combined with BPC-157 for enhanced tissue repair, or with TB-500 for comprehensive healing protocols. It also pairs well with collagen supplements for skin support.
How should GHK-Cu capsules be stored?
Store at room temperature in a cool, dry place away from direct sunlight. Refrigeration is not required but can extend shelf life. Keep the container tightly sealed.
