# Epithalon

> Epithalon (also spelled Epitalon) is a synthetic tetrapeptide (Ala-Glu-Asp-Gly) modeled on epithalamin, a pineal gland extract studied extensively by Russian gerontology researchers since the late twentieth century. It has been investigated mainly for possible effects on telomerase activity, circadian rhythm regulation, and general biological aging markers. Most available data come from animal studies and a limited number of small human trials conducted outside rigorous Western regulatory review. It remains an investigational compound without broad regulatory approval, and long-term human safety and efficacy are not well established.

- Storage: Store lyophilized peptide frozen or refrigerated; reconstituted solution refrigerated and used within 2-4 weeks

## Mechanism of action

Epithalon has been proposed to activate telomerase, an enzyme that extends chromosome-end repeat sequences, in some cell lines studied in vitro and in animal models. It may also influence pineal gland regulation of melatonin secretion, potentially supporting circadian rhythm normalization. Some researchers hypothesize antioxidant and gene-expression-modulating effects, though precise molecular pathways in humans remain incompletely characterized.

## Reported benefits

- May support healthy circadian rhythm and sleep patterns
- Studied for potential telomerase-related cellular effects
- Explored as part of general anti-aging research protocols
- May support antioxidant balance in some animal models

## Reported side effects

- Injection site irritation
- Mild fatigue or drowsiness
- Headache
- Limited long-term human safety data

## Common protocols

- 10-20 day subcutaneous course once or twice yearly
- Evening administration proposed to align with circadian melatonin release

## Stacking notes

Sometimes discussed alongside other longevity-focused peptides; no controlled human data on combination effects exists
