At just two amino acids in length, Vilon is the shortest peptide known to have biological activity. Research shows that Vilon has potent anti-aging effects and that it is a powerful regulator of immune function. There is also good evidence that Vilon helps to regulate the vascular system and promotes hemostasis. Vilon has been shown to reduce the incidence and growth of spontaneous tumors, though its role as an adjuvant in cancer treatment (as opposed to prevention) has been called into question. Overall, Vilon has several staunch advocates, such as Dr. Vladimir Anisimov, who feel that the peptide is a useful geroprotective agent.
