Epithalon (Epitalon), synthetic tetrapeptide (Ala-Glu-Asp-Gly)
A synthetic pineal-derived tetrapeptide studied primarily in laboratory settings for its proposed role in telomerase activity and cellular aging research.
Laboratory studies have proposed that Epithalon may interact with telomerase activity, the enzyme responsible for maintaining telomere length. Separately, some research has explored its relationship to pineal gland signaling and melatonin-related rhythms. These proposed mechanisms remain under investigation.

Proposed telomerase & pineal gland signaling
Cellular aging & circadian pathways
Longevity-related research outcomes under study
Human Research
A small number of older published studies, primarily from Russian research groups, have examined Epithalon in limited human populations. These studies have not been widely replicated in rigorous, independent clinical trials.
Preclinical Research
Laboratory and animal research has explored telomerase activity and lifespan-related markers following Epithalon exposure.
What We Don't Know Yet
Whether Epithalon meaningfully affects human telomere length, aging markers, or longevity outcomes has not been established through rigorous modern clinical trials. Long-term safety data is limited.
Epithalon is primarily discussed in longevity research circles because of its proposed telomerase connection.
Its relationship to pineal gland function has led to interest in circadian rhythm and sleep-related research.
Some research has examined oxidative stress and cellular markers alongside Epithalon exposure.
Someone interested in longevity science or cellular aging research may encounter Epithalon while exploring telomere-related peptide therapies.
Whether a therapy is appropriate depends on individual health history, medications, goals and clinician evaluation.
Epithalon is not approved by the FDA for any medical use and is not an FDA-approved drug product.
Evidence remains limited and largely preliminary. Modern, independently replicated human clinical trials are scarce. Discuss any interest in longevity-focused peptide therapies with a licensed healthcare provider.

A naturally occurring coenzyme central to cellular energy production, studied for its relationship to fatigue, aging, and metabolic function.

A growth hormone releasing hormone fragment with a longer research and clinical history than many newer growth hormone secretagogues.
