Why Clavicular Uses This Peptide
GHK-Cu is the GLOW peptide in Clavicular's stack — collagen synthesis and skin restoration during rapid fat loss.
See Clavicular's complete looksmaxxing stack →Copper Delivery & Gene Expression Modulation
GHK-Cu (Glycyl-L-Histidyl-L-Lysine copper complex) is a naturally occurring copper-binding tripeptide found in human plasma, saliva, and urine. Its concentration declines significantly with age. GHK-Cu modulates the expression of over 4,000 human genes — approximately one-third of the human genome — promoting wound healing genes while downregulating inflammatory and cancer-promoting pathways. Its copper-binding capacity delivers Cu²⁺ to cuproenzymes including lysyl oxidase (collagen/elastin crosslinking) and superoxide dismutase (SOD1/SOD3).
Research Highlights
Collagen & Skin Matrix Research
GHK-Cu stimulates collagen types I, III, and IV synthesis by fibroblasts, activates metalloproteinases for old collagen breakdown, and upregulates TIMP-1/2 to prevent excessive matrix degradation. In vitro studies show increased dermal thickness and tensile strength.
Wound Healing
GHK-Cu accelerates wound healing in multiple animal models through angiogenesis promotion, keratinocyte migration, and anti-oxidant defense (via SOD activation). It has been studied in human clinical trials for wound and ulcer healing.
Anti-Aging Gene Expression
Microarray analysis shows GHK-Cu reverses the gene expression signatures of aged skin — upregulating repair, remodeling, and mitochondrial genes while downregulating inflammatory and oncogenic pathways. Pickart's foundational research identified 4,000+ gene targets.
