Evidence strength
Higher = more and better-quality human evidence. It does not mean the effect is bigger or that the compound works for you.
Higher = more mature, better-documented human safety data. It does not mean the compound is safer than one with a lower number.
The 0-100 values rate the strength and maturity of evidence, not how effective or safe the compound is.

Overview
Higher = more and better-quality human evidence. It does not mean the effect is bigger or that the compound works for you.
Higher = more animal, tissue or cell research. Preclinical results are a starting point, not proof of a human benefit.
Higher = more mature, better-documented human safety data. It does not mean the compound is safer than one with a lower number.
How to read these scores
Every number here rates the evidence, not the compound. They are editorial 0-100 strength ratings, not percentages, and not a rating out of five stars.
- Human efficacy evidence strength — Higher = more and better-quality human evidence. It does not mean the effect is bigger or that the compound works for you.
- Preclinical evidence strength — Higher = more animal, tissue or cell research. Preclinical results are a starting point, not proof of a human benefit.
- Human safety evidence strength — Higher = more mature, better-documented human safety data. It does not mean the compound is safer than one with a lower number. A score of 80 does not mean “80% safe”.
- Evidence level (L0-L5) — the strongest type of study behind the compound, from anecdote (L0) to large replicated human trials (L5). It is a description of the study evidence, not a quality, safety or recommendation rating.
- Confidence — how likely we think it is that this rating changes as new research lands. Low confidence means the picture is unsettled, not that the compound is bad.
None of these ratings is medical advice, a safety guarantee, or a recommendation to use anything. How we grade evidence.

Routes & formulations
Marketed / research routes — never approved
The cited work is cell culture and molecular docking. No human route has been validated.
Route availability is not evidence of efficacy, and evidence from one route does not transfer to another. The Registry never provides dosing or sourcing information.

What it is
A short synthetic peptide from the St Petersburg bioregulator network. It is usually reported as the tripeptide Lys-Glu-Asp (KED); KED appears by sequence in academic work from the same network, but the cited Vesugen abstract itself does not state the sequence. Vesugen is not the same as the vendor name 'Vesilute/Vesilut', whose identity is unresolved.
What people claim
- Vascular protection
- Anti-ageing of blood vessels
What the evidence actually says
A 2014 study reported increased Ki-67 (a proliferation marker) in tissue-specific and vascular endothelial cell cultures from young and old animals, plus computer docking to the MKI67 gene promoter. This is cell and in-silico work only and is not evidence of vascular benefit in people.

Safety Centre
What approved, investigational and unapproved actually mean for documented human safety.
Human evidence
- No registered, independent, controlled human trial of Vesugen was identified.
- The 2014 abstract refers to a vasoprotective effect 'revealed previously in elder people'; that earlier work was not identified or verified here.
Preclinical evidence
- Cell cultures from young and old animals and vascular endothelial cultures: increased Ki-67 expression; molecular docking to the MKI67 promoter (Khavinson et al., Adv Gerontol 2014, PMID 25051766, Russian).
Animal and cell findings are Level 1–2 evidence.
Mechanism and pathways
- Proposed epigenetic regulation of Ki-67 gene expression; based on docking and cell data only.
Safety and unknowns
- No human safety data identified.
- Material sold online is unregulated: identity, purity, sterility and labelled quantity are separate questions from what the published molecule does.
Cancer relevance
This section covers questions raised by how the compound works in the body, plus anything regulators and trial teams keep an eye on. It is not a statement that this compound causes cancer — for most compounds here, no human data exist in either direction.

Regulatory status
Regulatory decisions apply to specific jurisdictions, products, formulations and indications. An approval elsewhere is not automatically an approval in your country.
Check the regulatory note and linked primary sources for jurisdiction-specific details.
Not an approved medicine in any major jurisdiction. Sale as a 'research chemical' is a legal and supply-chain statement, not evidence of benefit or harm.
Evidence grade
Mechanistic rationale or early development without qualifying compound-specific outcome evidence. A registered trial is not a result.
What would change our rating?
- A primary paper that names Vesugen and fixes its sequence.
- Independent replication and a registered controlled human study.

Review provenance
Registry editorial review: Colin Jackson-White, creator and editor, who is not a doctor or clinician. External specialist review is credited only when a named reviewer has completed a review of this exact profile.
Literature-discovery and AI tools may help locate or challenge candidate evidence, but they are not counted as evidence sources here. Registry judgements are tied to the underlying papers, trial records, regulator documents and official study records.

Source hierarchy: regulatory documents and trial registries first, peer-reviewed work next, sponsor material flagged as non-independent. We never use supplier or clinic marketing as evidence, and where a verified source has not yet been curated we say so rather than inventing one.
