Vesugen vs Thymulin

Side-by-side comparison of key properties, dosing, and research.

Anti-Aging & Longevity
Vesugen
Immune Support
Thymulin
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.
Thymulin is a nonapeptide hormone produced exclusively by the thymic epithelium. It requires zinc for biological activity and plays a critical role in T-lymphocyte maturation, differentiation, and immune regulation. Thymulin levels decline dramatically with age, contributing to immunosenescence.

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
  • Enhances T-cell maturation and differentiation
  • Boosts NK cell cytotoxic activity
  • Reduces inflammatory cytokine production (TNF-α, IL-1)
  • Anti-nociceptive (pain-reducing) properties
  • Restores age-related immune decline
  • Anti-inflammatory via serotonin pathway modulation
Side Effects
  • Generally well tolerated
  • Mild injection site reactions
  • No significant vascular adverse events reported at standard doses
  • Injection site reactions
  • Mild fatigue initially as immune system activates
