Gonadorelin
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.
Gonadorelin is the synthetic form of endogenous GnRH (gonadotropin-releasing hormone). It stimulates the pituitary to release LH and FSH, maintaining testicular function and testosterone production. Widely used alongside TRT to prevent testicular atrophy and preserve fertility.
Half-Life
Short (minutes); gene-regulatory effects are sustained
~2–4 minutes (extremely short); pulsatile dosing required to avoid desensitization
Admin Route
SubQ, Oral
SubQ, Intranasal
Research
Typical Dose
10 mg per day
100 mcg
Frequency
Daily for 10–30 days
Twice daily (every 12 hours)
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
  • Maintains testicular size during TRT
  • Preserves fertility and sperm production during testosterone use
  • Stimulates endogenous LH/FSH production
  • Maintains HPG axis function during exogenous hormone use
  • Used for HCG-free TRT protocols
  • Helps restart natural testosterone production (PCT)
