How Epithalon is prescribed.
- Adults interested in longevity-focused protocols
- Patients whose physician wants a short, cyclical course rather than continuous use
Your physician decides whether Epithalon is appropriate for you after reviewing your intake and labs.
Inject 0.25 mL (25 units) subcutaneously once daily Monday through Friday.
- Licensed physician review of your intake, history, and labs
- Medication compounded to your prescription by a PCAB-accredited, FDA-registered pharmacy
- Every batch independently tested before release
- Sterile syringes and alcohol prep pads for injectables
- Tracked delivery to your door, refills on schedule
- Message your physician anytime; dose changes without an appointment
- Store refrigerated (36–46°F / 2–8°C) at all times, including before first use.
- One vial is your monthly supply. A fresh vial ships every 28 days on your refill schedule, so you're always well inside the beyond-use date on your label.
- Protect from light. Wipe the stopper with an alcohol pad before every draw.

How Epithalon works, and what the research shows.
Epithalon (Epitalon) is a tetrapeptide that activates telomerase — the enzyme that maintains telomere length.
Based on decades of research by Dr.
Vladimir Khavinson.
May slow cellular aging and extend healthspan.
Epithalon (epitalon) activated telomerase and lengthened telomeres in human cell cultures in work from the Khavinson group, and small long-term Russian studies in elderly patients reported favorable outcomes.
Bull Exp Biol Med 2003That human data comes from limited, decades-old studies that have not been replicated in modern Western randomized trials — epithalon remains an investigational longevity peptide.
