Epitalon has some older human research in narrow clinical settings and newer laboratory work on ageing-related biology. That does not establish that it extends human lifespan or works as a general anti-ageing treatment.
Still uncertain: Human lifespan extension, systemic anti-ageing benefit, general sleep benefit, long-term systemic safety or a validated longevity regimen.

What does the evidence mean in simple terms? table
What is it?
Tetrapeptide
Entity type
Peptide
Research focus
Ageing biology, telomere research, retinal research
Human evidence
Older regional human evidence includes a 162-patient retinitis-pigmentosa study using a highly specific parabulbar route. Modern 2025 telomere findings are in cultured human cells, not a longevity trial. No large independent human lifespan trial was identified.
Regulatory status
Not FDA-approved; compounded-use safety information is insufficient.
Main limitations
Human lifespan extension, systemic anti-ageing benefit, general sleep benefit, long-term systemic safety or a validated longevity regimen.
Safety
Modern human safety and efficacy datasets are inadequate; FDA lists lack of safety information for compounded epitalon.

Outcome-level evidence
Evidence is not one score.
Each record below answers a narrower question about an outcome, population or context. Evidence status and the study finding are shown separately so strong evidence is not mistaken for a positive effect.
Modern human safety and efficacy datasets are inadequate; FDA lists lack of safety information for compounded epitalon.
Systemic long-term human safety is not established; telomere/telomerase effects require careful interpretation, especially because cancer-cell models can respond differently.
Technical details
Mechanism / biologyInvestigated for gene-expression, telomerase/telomere and pineal/retinal biology.
Route / formulation boundaryDo not confuse Epitalon (tetrapeptide) with Epithalamin (pineal extract) when citing older literature.
Identity / data-quality noteSynthetic Epitalon must not be conflated with Epithalamin/pineal extract studies.
Study / label regimen evidenceVerified historical human retinal-study exposure added. A historical retinitis-pigmentosa study used 5.0 µg per eye by parabulbar injection for 10 consecutive days. That study exposure does not establish a general systemic or longevity dose.
WhichPeps does not rely on a single headline study when the evidence base is broader. Primary research, registries, regulators and supporting records are kept distinct.
2structured study records
3outcome records
6linked source records
How to read these counts: they show evidence coverage, not evidence strength. One large, well-designed study can be more informative than several weak or indirect records.
Show supporting and discovery sources
Study pages above contain the records used for public evidence summaries. The links below include supporting, regulatory and literature-discovery sources; a registry or search result is not treated as proof of benefit.

Evidence rule: WhichPeps keeps human, animal, laboratory, regulatory and product/formulation evidence distinct. Common names help people find the page; they do not change the underlying scientific identity.
