Summary
Vesugen is a tripeptide bioregulator (Lys-Glu-Asp) developed by Professor Vladimir Khavinson, tissue-specific for blood vessels and the vascular endothelium. It supports endothelial cell function, promotes vascular wall integrity, and is studied for atherosclerosis prevention, vascular aging, and cardiovascular health maintenance. It is one of the more broadly applicable Khavinson bioregulators given the ubiquity of vascular tissue.
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
  • Supports vascular endothelial cell function and integrity
  • May reduce endothelial inflammation and dysfunction
  • Anti-aging effects on blood vessel walls
  • Potential benefits in early atherosclerosis and vascular aging
  • Supports nitric oxide-mediated vascular tone
  • Reduces endothelial apoptosis from oxidative stress
  • Complementary to Cardiogen and Epithalon in cardiovascular longevity protocols
