> A natural thymus peptide complex (Cytomax A-6) — the extract-based counterpart to Thymalin, marketed for immune support and aging.

- Also known as: A-6 thymus peptide, thymus peptide complex
- Class: Immune, Bioregulators
- FDA approved: No

## Overview

Vladonix is a natural peptide complex extracted from thymus tissue (peptide complex A-6), part of the Russian Cytomax / Revilab line of tissue bioregulators. It is an extract-based immune bioregulator in the same lineage as Thymalin, marketed within the Khavinson tradition for immune restoration and healthy aging.

Vladonix is the thymus-directed natural bioregulator of the Cytomax / Revilab line — the extract that sits alongside the thymic peptides already catalogued: Thymalin (the classic thymus extract) and Thymogen (the minimal Glu-Trp dipeptide). It featured in the long-running Khavinson observational work on immune-function markers with aging.

As a tissue extract it is a standardized polypeptide fraction, not a single defined molecule, so it has no molecular formula or sequence. Its claims — immune restoration and aging-related endpoints — come from the same concentrated research tradition as the rest of the series, with limited independent replication. It is a research compound / supplement and is not FDA-approved.

## Mechanism

Proposed tissue-selective (bioregulator) modulation of thymic / immune-cell gene expression, in the thymic-peptide tradition of Thymalin and Thymogen.

## Research areas

Studied in: Immune modulation, Aging biology, Peptide bioregulators.

## Key research

- Thymus bioregulator — a natural thymic peptide extract (complex A-6) in the immune-support lineage of Thymalin.
- Immune / aging focus — associated with the Khavinson observational work on immune markers with age.
- A tissue extract — a polypeptide fraction with no single formula or sequence.
- Evidence quality — concentrated in one research tradition; preliminary. Not FDA-approved.

## Storage, handling & synthesis

**Synthesis.** Vladonix is a natural thymus peptide extract (complex A-6), not a synthesized molecule — a fractionated polypeptide preparation like Thymalin, where batch-to-batch consistency and characterization, not coupling chemistry, are the quality challenge.

## FAQs

### What is Vladonix?

Vladonix is a natural thymus peptide complex (Cytomax A-6) marketed for immune support and healthy aging, the extract-based counterpart to Thymalin.

### How does it relate to Thymalin and Thymogen?

All three are thymic peptides: Thymalin and Vladonix are thymus extracts, while Thymogen is the minimal synthetic dipeptide (Glu-Trp) distilled from that tradition.

### Does it have a molecular formula?

No — it is a tissue extract (a polypeptide fraction), so it has no single sequence or molecular formula.

### Is Vladonix approved?

No — it is a research compound / supplement, not FDA-approved, with evidence concentrated in one research tradition. This page is a research and educational reference.
