Livagen
Khavinson tetrapeptide bioregulator (Lys-Glu-Asp-Ala) with epigenetic effects on liver and chromatin — one of the first peptides demonstrated to decondense heterochromatin in senescent cells.
🔬 Mechanism of Action
Livagen (Lys-Glu-Asp-Ala, KEDA) is a tetrapeptide with unique epigenetic properties — it was one of the first peptides demonstrated to decondense pericentromeric heterochromatin in senescent cells. This heterochromatin reactivation restores access to genes that had been silenced by aging-associated chromatin compaction.
Beyond its epigenetic effects, Livagen targets liver tissue specifically, modulating hepatocyte gene expression for detoxification enzymes (CYP450 family), albumin synthesis, and regenerative pathways. This dual mechanism — epigenetic rejuvenation + hepatoprotection — makes it unique among bioregulators.

📜Background & History
Livagen (Lys-Glu-Asp-Ala) is notable for being one of the first peptides proven to decondense pericentromeric heterochromatin — literally "unlocking" genes silenced by aging. This epigenetic effect plus hepatoprotection makes it unique among bioregulators.
🎯 Research Use Cases
- ✓Epigenetic rejuvenation research
- ✓Hepatoprotection and liver regeneration
- ✓Anti-aging through chromatin remodeling
- ✓Liver detoxification support

🧪 Reconstitution Example
⚠️Safety & Considerations
Standard Khavinson protocol. The epigenetic effects (heterochromatin decondensation) are tissue-selective and do not appear to cause inappropriate gene activation. Well-tolerated with 30+ years of data.
⚡Interactions & Contraindications
Standard Khavinson protocol. Epigenetic effects are tissue-selective. Well tolerated.
🔗Synergies & Common Stacks
Livagen (heterochromatin decondensation) + Epitalon (telomerase activation) = dual epigenetic aging intervention targeting both gene accessibility and telomere maintenance.
Livagen (synthetic hepatoprotective peptide) + Svetinorm (liver Cytomax extract) = comprehensive liver support through complementary bioregulator approaches.
