Livagen vs Thymulin

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

Anti-Aging & Longevity
Livagen
Immune Support
Thymulin
Summary
Livagen is a dipeptide bioregulator (Lys-Glu) developed by Professor Vladimir Khavinson, tissue-specific for the liver and thymus. It supports hepatocyte function, promotes liver cell regeneration, and modulates immune function via thymic activity. Research suggests benefits in chronic liver disease, hepatic aging, and immune restoration following liver damage.
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 hepatocyte regeneration and liver tissue repair
  • Normalizes liver cell protein synthesis
  • Immune modulation via thymic activity
  • Potential benefits in chronic hepatitis and liver aging
  • Anti-aging effects on hepatic tissue
  • May support liver recovery after toxic insult or alcohol damage
  • Complementary to NAD+ and glutathione in liver health 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 hepatotoxic effects reported at standard doses
  • Injection site reactions
  • Mild fatigue initially as immune system activates
