Epithalon (Epitalon) is a synthetic tetrapeptide (Ala-Glu-Asp-Gly) derived from the pineal gland peptide Epithalamin. Unlike most research peptides that are used in continuous cycles, Epithalon is administered in short, intensive courses — typically 10–20 days — once or twice per year.
Why Short Courses?
The short-course protocol mirrors the original research by Professor Vladimir Khavinson, whose work established the foundation for Epithalon's use in longevity medicine. The mechanism — telomerase activation and pineal gland normalization — appears to produce durable effects that persist well beyond the administration window. Continuous daily use is not associated with additional benefit and may blunt the pulsatile signaling that drives the pineal effects.
The Protocol
| Parameter | Standard Protocol | Aggressive Protocol |
|---|---|---|
| Daily Dose | 5–10mg | 10–20mg |
| Course Length | 10 days | 20 days |
| Frequency | 1–2x per year | 2x per year |
| Timing | Before bed | Before bed |
Timing: Why Before Bed?
Epithalon's pineal gland effects are best aligned with the body's natural melatonin secretion cycle, which peaks during sleep. Administering before bed synchronizes the peptide's activity with the pineal gland's natural rhythm. Many researchers also report improved sleep quality during Epithalon courses — a secondary benefit of pineal normalization.
