Synthetic tetrapeptide bioregulator
Also known as: Epithalon, Epitalon tetrapeptide, AEDG peptide
Epitalon (also transliterated Epithalon) is the tetrapeptide Ala-Glu-Asp-Gly associated with Russian peptide-bioregulator research. Proposed effects include modulation of gene expression, circadian biology, oxidative stress, and telomerase-related pathways, but mechanisms and clinical relevance remain uncertain.

What we know
The project separates represented evidence from qualification, contradiction, uncertainty, and what the evidence does not establish.
This does not mean the scientific literature contains no findings. It means no reviewed institutional claim has been represented here.
Scientific context
Existing reviewed chemistry is preserved as scientific context. Chemistry and mechanism information do not establish clinical efficacy or safety.
Chemical identity describes the recorded molecular information. It does not establish biological activity, clinical efficacy, safety, or therapeutic suitability.

Traceability
The experience makes incomplete links visible instead of presenting a false impression of perfect provenance.
Source publication state
A governed source may be verified and approved for publication while its claim-to-evidence link is still incomplete.
Reviewer provenance state
“Human scientist reviewed: no” means that specific source-path attribution is not recorded. It does not silently negate the separate publication-review state.

Epitalon evidence · ranking key
A tier describes the evidentiary role and design strength of a source. It is not a popularity score, proof that every conclusion is correct, or a substitute for claim-level review.
Large, well-conducted randomized trials; prespecified major outcomes; rigorous systematic reviews or meta-analyses; and major regulatory assessments.
Smaller randomized trials, strong prospective cohorts, prespecified secondary analyses, and high-quality comparative-effectiveness studies.
Retrospective cohorts, claims-database studies, pharmacovigilance analyses, mechanistic human research, and well-documented case series.
Case reports, conference abstracts, preclinical research, hypothesis-generating analyses, and expert commentary.
Tier classifies source design and evidentiary role. Confidence reflects risk of bias, sample size, comparator quality, outcome relevance, follow-up, missing data, directness, replication, reporting quality, and whether conclusions stay within the measured results.

Funding and conflicts are disclosed and considered, but sponsorship never automatically changes a tier. Corrections, retractions, and expressions of concern override the original rating.
This is a representative, sequence-derived model ordered by residue position only. It is not the peptide's experimentally determined or predicted biological conformation, and it carries no claim about real bond angles, distances, secondary structure, binding sites, or activity.
