GHK-Cu Copper Peptide: Research Applications and Findings

Peptide Profiles — 2026-04-08

GHK-Cu (glycyl-L-histidyl-L-lysine copper complex) is a naturally occurring copper peptide found in human plasma, saliva, and urine. First identified in 1973, it has since become one of the most studied peptides in regenerative and anti-aging research.

What Is GHK-Cu?

GHK-Cu is a tripeptide (three amino acids: glycine, histidine, lysine) with a strong affinity for copper ions. The copper complex is what gives this peptide its unique biological properties. GHK-Cu levels in the body naturally decline with age, dropping from about 200 ng/mL at age 20 to 80 ng/mL by age 60.

Research Areas

Skin and Wound Healing The most extensive body of GHK-Cu research relates to skin biology: - Stimulation of collagen synthesis (types I and III) - Increased elastin production - Enhanced glycosaminoglycan synthesis - Accelerated wound contraction and closure - Angiogenesis promotion in wound beds

Hair Follicle Research Studies have explored GHK-Cu's potential effects on hair follicles: - Increased hair follicle size in research models - Stimulation of follicle growth phase - Potential DHT-blocking effects

Gene Expression Perhaps the most fascinating area of GHK-Cu research is its effect on gene expression. Studies have shown GHK-Cu can modulate the expression of over 4,000 genes, including: - Upregulation of DNA repair genes - Suppression of inflammatory genes - Activation of stem cell-related genes - Modulation of antioxidant response genes

Anti-Inflammatory Effects GHK-Cu has demonstrated significant anti-inflammatory properties: - Suppression of pro-inflammatory cytokines (IL-6, TNF-alpha) - Reduction of oxidative stress markers - Modulation of TGF-beta signaling

Forms of GHK-Cu

GHK-Cu is available in several forms for different research applications: - Injectable — For systemic research applications - Topical — For skin and wound healing studies - Lyophilized powder — For custom formulation research
