Epitalon
Peptide ·Exploratory record · not publication-reviewed ·Updated July 13, 2026
Epitalon is a synthetic tetrapeptide promoted for circadian rhythm, telomerase, and longevity effects. It is not FDA-approved, and most human longevity claims come from limited Russian literature or cell studies rather than large independent trials. Use should be considered research-only, especially for injectable products.

What the research says.
A quick, data-only summary. The full evidence, dosing, and sources are below.
Epitalon is a peptide most often used for pineal and circadian research interest, in vitro telomerase research, animal longevity literature. NutriStack rates the overall evidence as insufficient. A typical adult dose is No FDA-approved human dose; no evidence-based longevity dose exists, commonly taken as not recommended for human use; research reagent only. This profile indexes 3 sources.
- Injection-site reaction
- Headache
- Sleepiness or vivid dreams
- Any unsupervised human use3
- Active cancer or history of cancer without specialist review
The bottom line
Evidence rating insufficient. Most-documented uses: pineal and circadian research interest, in vitro telomerase research, animal longevity literature. 3 sources indexed (2003–2025), with 0 interaction records on file.
How it works, mechanistically.
Core mechanism
Epitalon is proposed to affect pineal and cellular aging pathways, including melatonin rhythms, telomerase activity, and gene expression involved in cell-cycle regulation. In vitro findings do not establish that intermittent peptide cycles extend human lifespan or are safe long term. Telomerase-related claims require caution because cell proliferation pathways are relevant to cancer biology.2,1
Dosing & protocol.
Peptides are generally not reliably orally bioavailable unless a specific studied oral formulation is used. Human use of research-grade products is not appropriate.
What it actually costs.
Real-world pricing across three quality tiers. Assumes Laboratory Research Reagent.
Research-market pricing is not a dosing recommendation; human use is not FDA-approved unless specifically stated. Updated 2026-06-04.
