GHK Peptide Guide (2026)
Complete Guide & Evidence (2026)
GHK (glycyl-L-histidyl-L-lysine) is the base tripeptide before copper binding. Activates wound healing genes, collagen synthesis.
GHK Multi-System Mechanism
Gene Expression
Activates 31.2% of aging-reversal genes. Upregulates collagen I, III, elastin synthesis. Reduces inflammatory gene expression
Antioxidant Defense
Upregulates SOD1, SOD2 (superoxide dismutase). Activates catalase and glutathione peroxidase. Reduces oxidative stress in aging tissue
Tissue Repair
Promotes nerve fiber growth and repair. Accelerates wound healing and angiogenesis. Lung and liver protective effects in models
Key Research Data
Proportion of aging-reversal genes activated by GHK in genome-wide expression studies.
Age-related decline
Reduction in plasma GHK concentration from age 20 to 60 — a key aging biomarker.
Topical concentration
GHK concentration range used in skin care formulations with clinical evidence for collagen effects.
Primary Applications
Skin anti-aging — collagen, elastin, barrier function via topical or subcutaneous use
Systemic longevity — gene expression modulation, antioxidant defense, tissue repair
Lung and liver protection — GHK shows tissue-protective effects in fibrosis models
GHK Protocol Overview
Note: GHK-Cu (copper-chelated form) is preferred for skin applications. GHK alone is used for systemic protocols. Both are research compounds. Track all skin, energy, and biomarker responses in the Shotlee app.
