Vesugen

aka Vesugen bioregulator · Lys-Glu-Asp · KED peptide

Vesugen is a synthetic tripeptide composed of lysine, glutamic acid, and aspartic acid (Lys-Glu-Asp), developed by Professor Vladimir Khavinson as a bioregulator peptide targeting the vascular system. It is designed to support endothelial function and microcirculation by modulating gene expression in vascular endothelial cells. Age-related vascular decline, characterised by endothelial dysfunction, reduced nitric oxide bioavailability, and impaired microcirculation, is a major contributor to cardiovascular disease and organ dysfunction. Vesugen is proposed to interact with DNA in endothelial cells to normalise transcription of genes involved in vascular homeostasis, including those regulating nitric oxide synthesis, angiogenesis, and endothelial integrity.

Lys-Glu-Asp

Read this before quoting the sequence
Tripeptide L-lysyl-L-glutamyl-L-aspartic acid, one of the Khavinson 'short peptide bioregulators'. The Vesugen = Lys-Glu-Asp identity is stated in an English-language PubMed-indexed paper from the originating group (Khavinson et al, Bull Exp Biol Med 2012: 'vesugen (Lys-Glu-Asp)'). PubChem does not carry 'Vesugen' as a synonym on the Lys-Glu-Asp record, so the chemistry below is that of the tripeptide, matched by name rather than by a registry cross-reference.

Mechanism of action

Vesugen (Lys-Glu-Asp) is theorised to penetrate endothelial cell membranes and interact with specific DNA sequences to modulate gene expression related to vascular function. Proposed targets include genes involved in endothelial nitric oxide synthase (eNOS) expression, prostacyclin synthesis, and endothelial cell adhesion molecule regulation. By potentially restoring youthful gene expression patterns in aging vasculature, Vesugen may support nitric oxide-dependent vasodilation, reduce endothelial inflammation, and improve microcirculatory blood flow.

What the evidence actually shows

Grade D

Evidence for Vesugen consists primarily of preclinical studies and observational data from Russian clinical practice. In vitro studies have shown effects on endothelial cell gene expression, and animal models have demonstrated improvements in microcirculation. No controlled human clinical trials meeting international standards have been published.

Regulatory status

Status
Not an approved medicine anywhere. No Drugs@FDA record, no DailyMed SPL, no EMA authorisation. Marketed in Russia and internationally as a dietary supplement / 'peptide bioregulator' rather than a drug.
Clinical stage
No ClinicalTrials.gov-registered trials. The only human data are small uncontrolled Russian-language gerontology reports (e.g. Adv Gerontol 2015, n=32, PMID 26390612), which report both claimed anti-ageing effects and prooxidant activity and inhibition of haematopoiesis.
WADA
Not named on the WADA 2026 Prohibited List.

Low-confidence pharmacokinetics
These figures are recorded as estimated rather than measured in a published PK study. Treat them as an order of magnitude. Anything downstream of them — accumulation, steady state, washout — inherits that uncertainty.

Handling and storage

No compound-specific stability data exists
No approved product and no regulatory label anywhere; no compound-specific stability data in any indexed publication. Ported storage text ('-20C ~24 months lyophilised; 2-8C ~4 weeks reconstituted') is generic peptide-handling boilerplate that was applied identically across many compounds in this dataset. It is not sourced to this compound. General peptide handling still applies — reconstitute gently, keep it cold, keep it dark — but any specific figure you see quoted for this compound elsewhere is someone's assumption, not a measurement.
