What it is
Livagen (KEDA; Lys-Glu-Asp-Ala) is a short peptide bioregulator associated with liver cell health, gene-expression regulation, chromatin reactivation, and aging-related cellular support.
Mechanism of action
Livagen is studied as a tissue-specific peptide bioregulator. Source literature describes effects on chromatin reactivation, gene expression, and physiologic function in aging and pathology models.
Evidence summary
Evidence is drawn from peptide-bioregulator and aging literature, including liver-polypeptide complex and KEDA studies. Human-grade dosing evidence is limited and should be interpreted conservatively.
Typical dosing protocols
- 20 mg vial reconstituted with 2.0 ml bacteriostatic water
- 1-2 mg subcutaneous daily
- 10-20 day courses, repeated 1-3 times yearly as needed
Side effects & safety
- Injection-site redness, tenderness, itching, or mild swelling
- Headache, fatigue, mild nausea, or digestive changes
- Use caution with complex liver disease or prescription medication regimens
