What is Vilon?
Vilon is a tiny synthetic peptide — just two amino acids linked together: lysine and glutamic acid (Lys-Glu). That makes it a dipeptide, one of the smallest peptide molecules studied in research. It belongs to a class called bioregulators — short peptides believed to act like natural signaling molecules that help the body regulate itself. Vilon was developed and studied primarily at the St. Petersburg Institute of Bioregulation and Gerontology in Russia, where researchers have investigated its potential role in aging, immunity, and cellular health. It is a research compound only and is not approved for human medical use.
How Vilon Works
Think of your DNA as a tightly wound ball of yarn. As cells age, more and more of that yarn gets knotted up — genes get locked away in dense, silent regions called heterochromatin — and the cell quietly loses its ability to do its job. Vilon appears to act like a careful pair of hands that gently unwinds some of those knots.
In laboratory studies using lymphocytes (immune cells) taken from elderly people, Vilon triggered a process called deheterochromatinization — essentially, it helped loosen tightly packed chromatin, reactivating genes that had gone quiet with age.[2] This included reawakening ribosomal genes (the instructions for making proteins), which is a big deal because protein production tends to slow down as we age.[2] Importantly, Vilon did not disturb the structural core of chromosomes — it was selective about which regions it influenced.[2]
Separately, researchers used DNA microarray technology — a tool that can read the activity of thousands of genes at once — to see what Vilon does inside mouse heart tissue. They scanned over 15,000 gene clones and found that Vilon changed the expression of 36 of them, switching some genes on and others off in specific patterns.[3] This suggests Vilon has precise, targeted effects on gene activity rather than a broad, non-specific impact.[3]
What the Research Shows
Lifespan and Biological Age
One of the most striking findings comes from a study in female CBA mice. When Vilon was given by subcutaneous injection starting at 6 months of age, the mice showed increased physical activity and endurance, lower body temperature, longer average lifespan, and fewer spontaneous tumors compared to controls.[5] Researchers described Vilon as showing promise for geroprotection — meaning protection against the processes of aging — and noted no harmful effects from long-term use in the animal model.[5]
Cancer and Immune Tissue
Experiments in mice transplanted with Lewis lung carcinoma showed that Vilon injections significantly increased the survival of the animals, pointing to what researchers call an oncomodulating action — the ability to influence how a tumor behaves.[4] In spleen tissue cultures, Vilon at very low concentrations also stimulated apoptosis (programmed cell death) in both young and old rat tissue.[4] One caution noted by the researchers: combining Vilon with the chemotherapy drug cyclophosphamide at the same time reduced survival — suggesting timing matters a great deal in how these compounds are used together.[4]
Gut Health and Nutrient Absorption in Aged Rats
Aging is known to impair how the intestine absorbs nutrients. In aged rats, daily oral administration of Vilon for one month improved how the small intestine transported glucose — both passively and actively — and boosted related enzyme activity.[6] This points to a potential role for Vilon in restoring intestinal function that declines with age.[6]
Chromatin and Cellular Rejuvenation
As described above, Vilon's ability to reactivate silenced genes in elderly human lymphocytes is one of its most studied mechanisms.[2] Researchers suggest this chromatin-level effect may underlie many of Vilon's other biological actions.[2]
What Vilon Is Being Studied For
- Geroprotection — slowing biological aging markers in animal models[5]
- Immune regulation — reactivating aged immune cells at the chromatin level[2]
- Oncomodulation — influencing tumor survival in transplant models[4]
- Apoptosis regulation — stimulating programmed cell death in lymphoid tissue[4]
- Intestinal function — restoring nutrient absorption in aged animals[6]
- Gene expression modulation — targeted changes to cardiac gene activity[3]
How Vilon Is Dosed in Research
Research doses of Vilon vary considerably depending on the experimental model and the outcome being studied. For example, doses used in tumor survival studies and lifespan research differ from the ultra-low concentrations used in cell culture apoptosis experiments. Rather than list every figure here, we recommend checking the dosage chart on this page for a full breakdown by study type, and using the calculator to work out volume-based amounts for your specific reconstitution. All dosing information is provided for reference and research planning purposes only.
Mixing and Storing Vilon
Vilon typically arrives as a lyophilized (freeze-dried) white powder. To reconstitute it, researchers commonly add bacteriostatic water or sterile saline slowly along the inside wall of the vial — never directly onto the powder — then gently swirl (do not shake) until fully dissolved. Because Vilon is a very small peptide, it dissolves easily. Once reconstituted, store the vial in the refrigerator (around 2–8°C) and use within a few weeks. For longer-term storage of unused powder, keep it frozen, away from light and moisture. Always label vials with the date of reconstitution. These are general research handling guidelines — always follow the specific protocols for your laboratory setting.
