# Ventfort

> A natural blood-vessel peptide complex (Cytomax A-3) — the extract-based counterpart to Vesugen, targeting vascular tissue.

- Also known as: A-3 vessel peptide, vascular peptide complex
- Class: Bioregulators
- FDA approved: No

## Overview

Ventfort is a natural peptide complex extracted from vascular (blood-vessel) tissue (peptide complex A-3), part of the Russian Cytomax / Revilab bioregulator line. It is the extract-based vascular counterpart to the synthetic tripeptide Vesugen (Lys-Glu-Asp), marketed within the Khavinson tradition for endothelial and vascular support.

Ventfort is the vessel-directed natural bioregulator of the Cytomax / Revilab line. It pairs with Vesugen, the synthetic Lys-Glu-Asp tripeptide already in this catalog: Ventfort is the natural vascular extract, Vesugen the defined synthetic short peptide modeled on the same tissue. In Khavinson protocols it is treated as a foundational entry because vascular function underlies every organ.

As a tissue extract it is a standardized polypeptide fraction with no single molecular formula or sequence. Its vascular claims come from the same concentrated research tradition as the rest of the series, with limited independent replication, and it is not FDA-approved.

## Mechanism

Proposed tissue-selective (bioregulator) modulation of vascular / endothelial gene expression, in the same lineage as the synthetic vessel peptide Vesugen.

## Research areas

Studied in: Vascular health, Aging biology, Peptide bioregulators.

## Key research

- Vascular bioregulator — a natural vessel peptide extract (complex A-3), the extract counterpart to synthetic Vesugen.
- Endothelial / vascular focus — marketed for vessel elasticity and endothelial support within Khavinson protocols.
- 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.** Ventfort is a natural blood-vessel peptide extract (complex A-3), a fractionated polypeptide preparation rather than a synthesized peptide. As with the other Cytomax extracts, consistency and characterization of the fraction are the quality challenge.

## FAQs

### What is Ventfort?

Ventfort is a natural blood-vessel peptide complex (Cytomax A-3), marketed for vascular and endothelial support — the extract-based counterpart to the synthetic peptide Vesugen.

### How does it relate to Vesugen?

Ventfort is the natural vascular extract; Vesugen is the defined synthetic tripeptide (Lys-Glu-Asp) modeled on the same tissue.

### 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 Ventfort approved?

No — it is a research compound / supplement, not FDA-approved. This page is a research and educational reference.
