Livagen (also known as LVGEN or Lys-Glu-Asp-Ala) is a synthetic tetrapeptide developed in Russia as part of the Khavinson peptide bioregulator family. It’s a short-chain amino acid sequence designed to mimic natural regulatory peptides, primarily targeting cellular repair and anti-aging processes. Unlike longer proteins, its small size allows it to penetrate cell membranes easily.

Chemical Structure

• Sequence: H-Lys-Glu-Asp-Ala-OH
• Molecular Formula: C₁₉H₃₃N₅O₉
• Molecular Weight: ~491.5 Da
• It’s typically supplied as a lyophilized powder for reconstitution in bacteriostatic water.

Purported Benefits and Mechanisms

Livagen is researched mainly for its cytoprotective (cell-protecting) effects, with studies focusing on:

• Epigenetic Regulation: Influences gene expression by normalizing chromatin structure in cells, potentially slowing age-related decline. Russian studies (e.g., by Vladimir Khavinson) claim it restores DNA function in aging tissues.
• Organ-Specific Effects:

• Anti-Aging: Short-term use (10-20 days) is said to extend telomeres and reduce markers of cellular senescence in preclinical trials.

Evidence Base:

• Primarily from Russian gerontology research (e.g., St. Petersburg Institute of Bioregulation and Gerontology). Peer-reviewed papers in journals like Bulletin of Experimental Biology and Medicine show benefits in rats and cell cultures (e.g., improved pineal gland function post-radiation).
• Limited Western clinical trials; mostly anecdotal or small human studies. No FDA approval—sold as a research chemical or supplement in some regions.

Usage and Dosage (Research Contexts)

• Administration: Subcutaneous injection or oral (capsules/nasal spray in some formulations).
• Typical Protocol (from peptide research communities):

• Stacking: Often combined with Epitalon (pineal peptide) or other Khavinson peptides like Pinealon.

Safety Notes:

• Generally well-tolerated in studies; side effects rare (mild injection site reactions).
• Not for human consumption without medical supervision—purity varies by source. Lab testing recommended (e.g., HPLC for >98% purity).
• Contraindications: Pregnancy, autoimmune conditions (theoretical immune modulation).

Where to Buy/Legal Status

• Available from peptide vendors (e.g., Peptide Sciences, Cosmic Nootropics) as “research only.”
• Legal in most countries for research; gray area for personal use (not scheduled).
