GHK
Summary
Cardiogen is a tetrapeptide bioregulator (Ala-Glu-Asp-Arg) developed by Professor Vladimir Khavinson. It is a tissue-specific bioregulator for the heart and myocardium, designed to normalize cardiomyocyte function and support cardiac tissue regeneration. Research has demonstrated cardioprotective effects, improved cardiac rhythm, and benefits in recovery from ischemic injury.
GHK is the natural tripeptide (Gly-His-Lys) released from human albumin that activates tissue remodeling, collagen synthesis, and anti-aging gene expression. The copper-free form is the biological signaling molecule; it chelates copper in tissue to form GHK-Cu but also has independent biological activity.
Half-Life
Short (minutes); gene-regulatory effects persist longer
Extremely short as free peptide; tissue binding extends local effects

Key Benefits
  • Cardioprotective effects on myocardial tissue
  • Normalization of cardiomyocyte protein synthesis
  • May improve cardiac rhythm and conduction
  • Support for recovery from ischemic cardiac events
  • Anti-aging effects on heart tissue
  • Potential reduction in cardiac fibrosis
  • Often combined with Epithalon for comprehensive cardiovascular longevity support
  • Stimulates collagen and extracellular matrix synthesis
  • Activates tissue repair gene expression programs
  • Anti-aging: reverses 57% of age-related gene changes
  • Antioxidant and anti-inflammatory
  • Wound healing and skin barrier repair
