Livagen
Summary
ARA-290 is a synthetic 11-amino acid peptide derived from the helix B region of erythropoietin (EPO). Unlike EPO, it selectively activates the innate repair receptor (IRR) without stimulating hematopoiesis, providing tissue protection, anti-inflammation, and neuropathy relief.
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.
