Epithalon
Epitalon (Epithalon)
Epithalon (Ala-Glu-Asp-Gly) is a synthetic tetrapeptide derived from the pineal gland peptide epithalamin, developed by Russian scientist Vladimir Khavinson. It is primarily studied for its telomere-lengthening properties, anti-aging effects, and potential to restore circadian rhythm regulation via modulation of melatonin synthesis in the pineal gland.
Mechanism of Action
Epithalon activates telomerase (hTERT), the enzyme responsible for elongating telomeres, which may slow cellular senescence and extend replicative lifespan in somatic cells. It also upregulates expression of genes involved in cell cycle regulation and acts on the hypothalamic-pituitary axis to normalize pineal gland function, increasing melatonin output and restoring disrupted circadian hormonal rhythms. Additionally, it exhibits antioxidant properties by reducing lipid peroxidation and modulating cytokine production.

Dosing Protocols
Morning or evening, subcutaneous injection into abdominal fat
Cycle: 10-20 day course, 1-2 times per year
Most studied and commonly used protocol mirrors original Russian clinical research: 10mg/day for 10 days administered as a course. Reconstitute lyophilized powder with bacteriostatic water. Some practitioners use 5mg/day for 20 days as an alternative.
Morning and evening
Cycle: 10-20 day course, 1-2 times per year
Intranasal administration is considered less bioavailable than injection and lacks robust clinical data; used primarily as a non-invasive alternative. Bioavailability is significantly lower than subcutaneous injection.
Safety & Side Effects
Epithalon has a generally favorable short-term safety profile based on Russian clinical studies spanning several decades, with no severe adverse events documented at recommended doses; however, long-term safety data in large Western populations is lacking. The theoretical oncological risk from telomerase activation warrants caution in individuals with a personal or family history of cancer, and it is sold exclusively as a research chemical in most Western countries with no approved human indication.
Possible Side Effects
- !Mild injection site redness or irritation (subcutaneous route)
- !Transient fatigue or drowsiness, particularly if used in the evening
- !Mild headache during initial days of a course
- !Nasal mucosal irritation with intranasal administration
- !Temporary disruption of sleep architecture during early use
- !Rare hypersensitivity or allergic reaction to peptide components
- !Theoretical concern of accelerated proliferation in pre-existing malignancies due to telomerase activation
Interactions
- -May potentiate the effect of melatonin supplements due to additive pineal axis stimulation ā monitor for excessive sedation
- -Theoretical interaction with immunosuppressants ā Epithalon's immunomodulatory effects may partially counteract immunosuppressive therapy
- -May enhance sensitivity to insulin or hypoglycemic agents by improving metabolic hormonal regulation ā monitor blood glucose
- -Additive antioxidant effects possible when combined with NAC, resveratrol, or other antioxidants ā generally benign but unstudied in combination
- -Use caution with anticoagulants as peptides influencing cell turnover and inflammation may subtly alter coagulation markers
Cost & Where to Buy
Sold as a research peptide by numerous vendors; cost reflects a typical 10-day annual course rather than continuous monthly use. A standard vial is 10mg lyophilized powder; a 10-day course at 10mg/day requires approximately 100mg total. Price varies significantly by vendor purity, third-party testing, and vial size.
