Noopept vs Livagen
Side-by-side comparison of key properties, dosing, and research.
- Summary
- Noopept is a potent dipeptide-derived nootropic from Russia, structurally related to piracetam but estimated to be 1,000 times more potent by mass. It enhances memory consolidation, learning, and recall while providing neuroprotection via BDNF and NGF upregulation.
- 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.
- Half-Life
- ~5–10 minutes but metabolite (CPG) effects last hours
- Short (minutes); gene-regulatory effects are sustained
