Livagen vs IGF-1 LR3

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

Anti-Aging & Longevity
Livagen
Anabolic & IGF
IGF-1 LR3
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.
IGF-1 LR3 is a synthetic analog of Insulin-like Growth Factor-1 with an extended half-life. It is one of the most potent anabolic peptides available, directly stimulating muscle cell hyperplasia and hypertrophy, and is the downstream mediator of many of GH's anabolic effects.

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
  • Direct muscle hypertrophy via IGF-1R stimulation
  • Muscle hyperplasia (new fiber formation) — unique among peptides
  • Rapid gains in lean muscle mass
  • Accelerated recovery from training and injury
  • Increased nutrient uptake by muscle cells
  • Fat oxidation enhancement
  • Bone density improvement
  • Cartilage and connective tissue repair
Side Effects
  • Generally well tolerated
  • Mild injection site reactions
  • No significant hepatotoxic effects reported at standard doses
  • Hypoglycemia (significant risk — insulin-like activity)
  • Acromegaly-like effects with excessive long-term use
  • Jaw and hand swelling
  • Organ hypertrophy with extreme doses
