GHK-Cu vs Livagen
Side-by-side comparison of key properties, dosing, and research.
- Summary
- GHK-Cu is a naturally occurring copper complex that declines with age. It is one of the most studied anti-aging peptides, known for powerful skin rejuvenation, wound healing, and tissue remodeling effects.
- 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.
