Sermorelin
Summary
Cortagen is a synthetic tetrapeptide (Ala-Glu-Asp-Pro) developed at the St. Petersburg Institute of Bioregulation as a cardioprotective and vascular bioregulator. It stimulates repair of cardiac and vascular tissue, with demonstrated benefits for coronary artery disease, atherosclerosis, and cardiac aging.
Sermorelin is a bioidentical synthetic peptide comprising the first 29 amino acids of naturally occurring GHRH. It is FDA-approved for diagnostic use and widely prescribed off-label for anti-aging, stimulating growth hormone production in a natural pulsatile pattern that mimics the body's own rhythm.

Key Benefits
  • Cardioprotective — protects cardiac tissue from ischemic damage
  • Promotes cardiac regeneration and repair
  • Improves vascular endothelium function
  • Reduces atherosclerosis progression
  • Anti-aging effect on heart muscle cells
  • Improves cardiac output and exercise capacity
  • Reduces oxidative stress in cardiovascular tissue
  • May reduce arrhythmia frequency
  • Increases energy and vitality
  • Improves body composition (more muscle, less fat)
  • Enhances skin thickness and elasticity
  • Strengthens immune system
  • Improves sleep quality and REM sleep
  • Supports bone density
  • Enhances mental clarity and focus
  • Safer than exogenous HGH — respects natural feedback loops
  • FDA-approved for GH diagnostic use
