Vilon
WellnessAlso known as: Lys-Glu, KE dipeptide, Thymus dipeptide bioregulator
Limited EvidenceWhat is Vilon?
The simplest of the Khavinson bioregulators: a synthetic dipeptide of lysine and glutamic acid (Lys-Glu). Originally derived from the thymus, Vilon is proposed to modulate immune function, reduce inflammation, and slow biological aging. Its small size gives it potentially higher oral bioavailability than larger bioregulator peptides — though this is theoretical.
How it works
The KE dipeptide is proposed to interact with PCNA (proliferating cell nuclear antigen) and histones in cell nuclei, modulating gene expression in immune and epithelial cells. Russian research suggests it acts as an immune system normalizer — stimulating immune function in immunocompromised states while dampening excessive inflammation. Its small size (just 2 amino acids) likely improves survival through gastric digestion compared to larger bioregulators.
What marketers claim
- ▸proven to extend human lifespan
- ▸complete immune restoration
- ▸reverses aging as measured by all biomarkers
- ▸safe at any dose
What evidence supports
- ✓extends lifespan in Drosophila and mice in Russian animal studies
- ✓Russian clinical data: reduced all-cause mortality in elderly populations with combined Vilon + Epithalon regimens
- ✓cell culture studies: KE peptide can modulate gene expression in immune and epithelial cell lines
- ✓small size makes oral administration theoretically more viable than larger bioregulator peptides
Research evidence
Key studies on Vilon, summarized in plain language. This is not an exhaustive list — it highlights the most relevant findings.
KE dipeptide extends lifespan and reduces tumor incidence in aged mice
Finding: Vilon (KE dipeptide) administration extended mean lifespan by 27% and reduced spontaneous tumor incidence vs controls.
Limitation: Animal study from the Khavinson group, rodent lifespan extension does not translate directly to human outcomes.

Course-based
Typically 10-day injection course or sublingual drops, 2–4× per year per Khavinson protocols.
Safety notes & concerns
Full safety guide →- ⚠evidence exclusively from Khavinson research group — no independent replication
- ⚠clinical trial quality below modern RCT standards
- ⚠dipeptide Lys-Glu not established as pharmacologically active in mainstream biology
- ⚠as a dietary supplement, the same dipeptide sequence appears naturally in many food proteins — specific bioregulator effect at physiological doses unestablished
Frequently asked questions
Is Vilon better than Thymalin since it is simpler?
They target somewhat different purposes in the Khavinson system — Thymalin is a complex thymic extract targeting T-cell renewal, while Vilon (KE dipeptide) has broader claimed immune-modulating effects. Vilon's main advantage is its simplicity: more stable, potentially orally bioavailable, and better characterized chemically than the full thymus polypeptide complex. Neither has strong evidence by modern Western standards.
