Livagen
Summary
Triptorelin is a synthetic decapeptide analog of gonadotropin-releasing hormone (GnRH) with 100x the potency of native GnRH. An FDA-approved drug (Trelstar) for prostate cancer and precocious puberty, it is also used in post-cycle therapy (PCT) to rapidly restart the hypothalamic-pituitary-gonadal (HPG) axis after anabolic steroid suppression.
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.

Key Benefits
  • Rapid HPG axis restart after steroid use
  • Single-injection PCT protocol possible
  • Massively elevates LH and FSH via flare effect
  • Restores endogenous testosterone faster than traditional PCT
  • FDA-approved for established medical uses
  • 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
Side Effects
  • Initial testosterone flare (intended)
  • Injection site reactions
  • Hot flashes (with chronic use)
  • Decreased libido (chronic dosing)
  • Generally well tolerated
  • Mild injection site reactions
  • No significant hepatotoxic effects reported at standard doses
