Does Vilon help with lifespan and tumour incidence?

D
Grade D — no human evidenceAnimal only · effect size: moderate
Short answerNo human evidence. As of 23 September 2026, only animal only exist for Vilon for lifespan and tumour incidence. Female CBA mice given vilon from six months lived longer and developed fewer spontaneous tumours in the institute's studies; the same group reports opposite-direction effects in other models.

Animal studies, cell studies, or anecdotes only. This is where almost every viral peptide sits. Promising and proven are different words for a reason.

In context

Vilon is the dipeptide lysine–glutamate, one of the short synthetic peptides derived by Vladimir Khavinson's St Petersburg institute from thymic extracts and sold as an immune and anti-ageing 'bioregulator'. Its indexed evidence is mice — longer lifespan and fewer spontaneous tumours in the institute's own studies — and cultured cells. No human trial of any design exists. It is not approved anywhere this site covers.

Vilon is not approved. Legal status differs by country — see the regulation section or the jurisdiction pages.
