Livagen peptide: Metabolic / Longevity research guide
In short: Livagen (Lys-Glu-Asp-Ala / KEDA) is a synthetic tetrapeptide from the Khavinson short-peptide family, designed from liver polypeptide preparations and studied in hepatocyte cultures and lymphocyte chromatin assays. It is studied in preclinical (cell and animal) research and is supplied strictly for laboratory use, not for human or clinical use.
Not medical advice. Livagen is a research compound. This guide does not provide dosing, diagnosis, therapy recommendations, or claims about effects in humans.

What Livagen is
Livagen (Lys-Glu-Asp-Ala, "KEDA") is a four-residue synthetic peptide from the Khavinson bioregulator family, studied in hepatocyte cultures, liver explants and lymphocyte chromatin assays.
One-paragraph overview from our research datasheet. Still scientific, but faster to read than the full mechanism list below.

Research contexts
Peer-reviewed papers discuss Livagen in specific lab settings. The points below reflect research questions, not health claims.
Research vs. personal use: Literature describes experiments in cells and animals. That is distinct from real-world use. Our products are for laboratory research only.
Typical study contexts
Why Metabolic / Longevity research matters
Researchers study these compounds for mitochondrial function and cellular energy stress. Ageing and metabolic disease models are common.
Mechanisms (technical review)
Our datasheet lists mechanistic themes from preclinical work. These are research endpoints, not health claims.
Lab handling & preparation
Common Questions People Are Asking
What is Livagen?
Livagen is the name used for the synthetic tetrapeptide Lys-Glu-Asp-Ala (KEDA), developed in the Khavinson short-peptide programme and paired with liver tissue. It is supplied here as a laboratory research powder only.
How is Livagen related to Vesugen?
The first three residues of Livagen (Lys-Glu-Asp) are the sequence of Vesugen. Livagen adds an alanine. The literature does not state a derivation between them; the relationship here is a sequence observation, not a published claim.
What does the research on Livagen show?
In cultured rat hepatocytes it was reported to raise protein synthesis, most in cells from old animals. In lymphocytes from elderly donors it was reported to decondense heterochromatin. It also inhibited enkephalin-degrading enzymes in serum. All of it is preclinical or in vitro and from the originating lineage and a Tbilisi group.
Is there a Certificate of Analysis for Livagen?
Not yet. No independent analytical report has been published for this material, so no purity figure is quoted.
Is there human data on Livagen?
The human-cell work is in vitro on lymphocytes. No interventional human study was found. Livagen is sold strictly for in-vitro and preclinical research, not for human or veterinary use.
Is this page medical advice? Can I use Livagen for my health?
No, and no. This article is educational only. We do not provide dosing, medical recommendations, or health claims. Our products are sold strictly for laboratory research, not for personal use of any kind.
