Vilon (Lys-Glu) is the smallest known immunomodulatory peptide, consisting of just two amino acids. Developed by Professor Khavinson, Vilon has been shown to stimulate thymic function, promote T-cell differentiation, and enhance immune system competence  particularly in aging organisms where thymic involution has reduced immune capacity. Research demonstrates that Vilon can partially reverse age-related immune decline and shows geroprotective (anti-aging) properties in animal models. Despite its simplicity, Vilon represents a significant advancement in peptide bioregulation research, demonstrating that even dipeptides can carry meaningful biological signals. Available in research-grade lyophilized form for immunology and longevity research.
