GHK-Cu

GHK-Cu (Glycyl-L-Histidyl-L-Lysine:Copper(II)) is a naturally occurring copper-binding tripeptide found in human plasma, saliva, and urine. First identified by Dr. Loren Pickart in the 1970s, GHK-Cu has been extensively researched for its remarkable ability to promote tissue remodeling, wound healing, and anti-aging effects. Plasma levels of GHK-Cu decline significantly with age - from approximately 200 ng/ml at age 20 to 80 ng/ml by age 60 - a reduction that correlates with diminished regenerative capacity.

The mechanism of action centers on the copper ion, which is essential for numerous enzymatic processes. GHK-Cu delivers bioavailable copper to cells, activating copper-dependent enzymes including superoxide dismutase (SOD), cytochrome c oxidase, and lysyl oxidase. These enzymes are fundamental to antioxidant defense, cellular energy production, and collagen crosslinking respectively. The peptide itself modulates the expression of over 4,000 genes, with most changes favoring a shift toward a more regenerative phenotype.

Skin research represents the most thoroughly documented application. GHK-Cu stimulates collagen synthesis (types I, III, and V), glycosaminoglycan production, and decorin expression. It also promotes the synthesis of metalloproteinases that remove damaged extracellular matrix components, effectively remodeling aged or scarred tissue. Studies demonstrate improvements in skin thickness, elasticity, firmness, and reduction of fine lines in treated skin.

Wound healing research shows that GHK-Cu accelerates contraction, improves re-epithelialization, and enhances granulation tissue formation. The peptide recruits macrophages and mast cells to wound sites, promotes angiogenesis, and stimulates nerve outgrowth - all critical components of the healing cascade. These effects have been documented across various wound models including burns, surgical incisions, and chronic ulcers.

Anti-inflammatory and antioxidant research has demonstrated that GHK-Cu reduces oxidative damage by upregulating antioxidant enzymes and suppressing pro-inflammatory cytokines including IL-6 and TNF-alpha. The peptide also inhibits the formation of reactive carbonyl species, which contribute to protein glycation and tissue aging.

Hair follicle research suggests that GHK-Cu may extend the anagen (growth) phase of the hair cycle by stimulating dermal papilla cells and promoting blood flow to the follicular unit.

For reconstitution, dissolve in bacteriostatic water using sterile technique. The resulting solution should have a characteristic blue color from the copper complex. Store at 2-8°C and use within 4 weeks.
