Vesugen
Research OnlyA synthetic tripeptide (Lys-Glu-Asp) developed by Russian scientist Vladimir Khavinson, claimed to support vascular health by modulating endothelial gene expression. The only published primary research is Russian in-vitro work on cultured endothelium. No animal vascular studies, no human clinical validation, and no regulatory approval anywhere.

Research Depth 6: highest tier is in-vitro only (1A=3) on cultured normal/ atherosclerotic/restenotic endothelium (Kozlov 28539025) and aging vascular cell cultures (Khavinson 25408528); zero human and zero animal data, so RoB (1B=0), precision (1C=0, human N=0) and directness (1D=1, cell-culture surrogate) floor out, with only a thin two-study preclinical base (1E=2). Mechanism 25: target inferred via epigenetic gene regulation with no measured binding/knockout (2A=10); proximal markers characterized (endothelin-1, connexin, sirtuin1, E-selectin) but full pathway not mapped (2B=8); no dose-response gradient (2C=2); in-vitro-only directness (2D=5). Plausibility 55: mechanism->surrogate marker shown but surrogate->clinical benefit is an unproven leap with no animal/human bridge (3A=15); directionally coherent with atherosclerosis biology on indirect markers (3B=19); analogous Khavinson short peptides T-38/RR-1 show similar in-vitro anti-atherosclerotic effects but all same lab (3C=10); tightly scoped vascular claim (3D=11). Global Coverage 11: all research from one group (St. Petersburg Institute of Bioregulation and Gerontology) in one country (4A=4, 4B=3), <5 relevant studies (4C=4), no regulatory recognition anywhere (4D=0). Community Experience 13: dossier notes no meaningful community discussion or user reports (5A=2, 5B=6, 5C=0); negligible documented exposure leaves no clean tolerability signal (5D=5). Effectiveness not-established: no quantified human efficacy estimate and no meaningful community effect signal.
The proposed mechanisms of Vesugen are based entirely on Russian research from the St. Petersburg Institute of Bioregulation and Gerontology. No independent Western validation exists.
How It Works (Simplified)
Vesugen targets vascular health through endothelial gene modulation and related pathways:
Binds to DNA sequences in endothelial cells, modulating expression of genes related to vascular tone, permeability, and cell function.
May influence nitric oxide signaling and endothelial-dependent vasodilation, supporting healthy blood flow and vascular reactivity.
Proposed to reduce oxidative stress in vascular tissue, protecting endothelial cells from age-related damage and dysfunction.
Claimed to counteract age-related changes in vascular gene expression patterns, potentially supporting healthier vascular aging.
Key Context: All research originates from the St. Petersburg Institute of Bioregulation and Gerontology (Khavinson’s institute). No independent Western validation exists for any claimed mechanisms.
Important Limitations
- 100% of research from Russian institutes associated with Khavinson
- No independent Western replication of any findings
- Only in-vitro (cultured-cell) studies exist; no animal vascular studies
- No human studies of any kind have been published
- Human pharmacokinetics, bioavailability, and optimal dosing unknown
- Translation from cell culture to meaningful cardiovascular benefits is unconfirmed
- Regulatory status: Not approved anywhere; unregulated research peptide
Based on in-vitro data only: changes in endothelial gene expression (e.g. endothelin-1, connexin) have been observed in cultured cells. No human time-course data exist.
PMID:28539025No animal or human dosing-response data exist for KED in vascular tissue. Russian protocols are described anecdotally as 10-20 day cycles, but these are not supported by published pharmacological studies.
In-vitro studies report effects on vascular-cell renewal markers (Ki-67, p53) and adhesion molecules (E-selectin). No measured effects in animals or humans are documented.
PMID:25408528No long-term human data exist. Optimal treatment duration and cycling protocols are not established, and human pharmacokinetics are unknown.
