GHK-Cu (Glycyl-L-Histidyl-L-Lysine copper) is one of the most extensively studied peptides in human biology. It is a naturally occurring copper complex found in human plasma, urine, and saliva — with concentrations declining significantly with age.
What is GHK-Cu?
GHK-Cu is a tripeptide (three amino acids: glycine, histidine, lysine) complexed with a copper ion. It was first isolated in 1973 and has since been the subject of hundreds of research studies examining its effects on wound healing, anti-aging, and tissue regeneration.
Research Applications
Collagen Synthesis
GHK-Cu is one of the most potent stimulators of collagen synthesis identified in research. It upregulates collagen and glycosaminoglycan synthesis, improving skin structure, elasticity, and wound healing capacity.
Hair Follicle Activation
GHK-Cu has been shown to stimulate hair follicle size and activate follicles in the telogen (resting) phase. Research has examined its topical and systemic applications for hair restoration.
Antioxidant & Anti-Inflammatory
The copper ion in GHK-Cu plays a role in superoxide dismutase activity. GHK-Cu has demonstrated antioxidant and anti-inflammatory properties in multiple research contexts.
Gene Expression
A 2012 study by Pickart et al. found that GHK-Cu modulates the expression of over 4,000 human genes — including genes involved in anti-aging, anti-cancer, and tissue repair pathways.
Dosage Protocol
Standard research dosage: 1–2 mg/day
Half-life: Approximately 24 hours
Administration: Subcutaneous injection after reconstitution, or topical application
Storage & Handling
Store lyophilized GHK-Cu at -20°C for long-term stability. Reconstitute with sterile or bacteriostatic water. Once reconstituted, store at 4°C and use within 4 weeks.
