Livagen- Summary
- Sermorelin is a bioidentical synthetic peptide comprising the first 29 amino acids of naturally occurring GHRH. It is FDA-approved for diagnostic use and widely prescribed off-label for anti-aging, stimulating growth hormone production in a natural pulsatile pattern that mimics the body's own rhythm.
- 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.
