Vilon

Vilon is a synthetic dipeptide (Lys-Glu) derived from the thymus gland, studied as an immune-regulatory bioregulator that promotes thymic function restoration and has been investigated in the same anti-aging peptide bioregulator research tradition as Epithalon and Thymalin. It represents one of the shortest bioactive peptides studied for immune modulation.

How Vilon works

Vilon is proposed to bind to specific nuclear chromatin sequences and modulate gene expression in thymic stromal cells and T-lymphocyte precursors, promoting thymopoiesis and restoring age-associated immunosenescence. As a dipeptide, it is remarkably stable to peptidase degradation compared to larger peptides and can be administered orally with some bioavailability. Preclinical and limited clinical data from Eastern European research suggests enhanced T-cell differentiation and improved immune function in aged subjects.

Thymalin

Moderate evidence

Immune

Thymalin is a thymic peptide preparation studied for immune system restoration and modulation, particularly in aging-related immune decline (immunosenescence) and post-illness immune reconstitution. It has been investigated in longitudinal anti-aging studies in Eastern European research literature with reported improvements in immune biomarkers.

Thymosin Alpha-1

Moderate evidence

Immune

An immunomodulatory peptide approved in over 35 countries (as Zadaxin) for hepatitis B/C and as an immune adjunct. Not FDA-approved in the US. Was placed on FDA Category 2 list (September 2023 – September 2024) before being removed when the nominator withdrew. Current regulatory status is in flux; FDA continues to flag safety concerns.

VIP

Preliminary evidence

Immune

Vasoactive Intestinal Peptide (VIP) is an endogenous 28-amino acid neuropeptide with potent anti-inflammatory, vasodilatory, and immunomodulatory properties, studied most notably in the context of Chronic Inflammatory Response Syndrome (CIRS) and pulmonary arterial hypertension. Intranasal delivery targets pulmonary and systemic anti-inflammatory pathways.
