Vilon

aka Lys-Glu

Immune Modulator

Mechanism

Vilon is a synthetic dipeptide (Lys-Glu / KE) from the Khavinson bioregulator series, originally derived from thymus extracts and studied in Russian preclinical models as an immunomodulator and geroprotector. Not FDA-approved; all published evidence originates from a single research group.

Overview of Epitalon-Highly Bioactive Pineal Tetrapeptide with Promising Properties
Araj SK, Brzezik J, Mądra-Gackowska K, Szeleszczuk Ł. · International journal of molecular sciences (2025) · review

Epitalon, also known as Epithalon or Epithalone, is a tetrapeptide, Ala-Glu-Asp-Gly (AEDG), which was synthesized based on the amino acids composition of Epithalamin, a bovine pineal gland extract, prior to its discovery in pineal gland polypeptide complex solution.
