Epitalon vs Epithalon Acetate
An educational, source-based comparison of Epitalon and Epithalon Acetate — how each peptide works, what it's researched for, and what to know before going deeper.
A synthetic tetrapeptide (Ala-Glu-Asp-Gly) modeled on epithalamin, a pineal gland extract. Research from Russian gerontology groups has examined effects on telomerase activity, melatonin rhythm, and lifespan in rodent and limited human cohorts.
- Telomerase activity (in vitro)
- Circadian and melatonin rhythm
- Age-related morbidity in long-term Russian cohort studies
- • Most research is Russian and methodologically heterogeneous.
- • Not FDA-approved.
- • Independent replication is limited.
An N-acetylated variant of Epitalon (Ala-Glu-Asp-Gly) designed to improve metabolic stability and oral bioavailability. Research suggests the same telomerase activation and circadian-modulating properties as the parent peptide.
- Telomerase activity and cellular senescence
- Melatonin rhythm regulation
- Age-related immune restoration
- • Preclinical data; limited human clinical trials.
- • Not FDA-approved.
Trial-evidence rating
Educational grade reflecting how many peer-reviewed studies and FDA actions we cite for each peptide. Not a clinical recommendation.
Two cited studies; independent replication needed.
Early-stage research; conclusions are tentative.
Study-by-study comparison
| Peptide | Study | Source | Year | Summary |
|---|---|---|---|---|
| Epitalon | Effect of Epitalon on telomere length in human somatic cells | Bulletin of Experimental Biology and Medicine | 2003 | Reported telomerase induction and telomere elongation in cultured cells. |
