Epithalon (also written epitalon or epithalone) is a synthetic tetrapeptide — four amino acids, Ala-Glu-Asp-Gly — derived from a pineal extract studied in Russia from the 1980s onward. It is most often discussed in relation to telomerase activity and circadian rhythm.

The published work on Epithalon is largely preclinical and from a small number of research groups. It is not an FDA-approved medication, and it has not been shown to extend lifespan, lengthen telomeres, or treat any condition in humans.

This is a compounded preparation, not an FDA-approved medication, and compounded drugs are not reviewed by the FDA for safety or effectiveness. Individual results are not guaranteed. It is prescribed only where a licensed provider determines it is appropriate after reviewing your health history.

Why people ask about it

Why does Epithalon come up?

Epithalon appears in longevity conversations because of laboratory work associating it with telomerase expression and with pineal and circadian function. That research is early, largely preclinical, and does not establish a clinical benefit in people.

✔A provider decides, not a quiz

Every Epithalon prescription here follows a review by a licensed provider of your health history, current medications and goals. If it isn't appropriate for you, it isn't prescribed.

✔Compounded, not a research chemical

Your vial is compounded by a licensed U.S. 503A pharmacy and dispensed against a prescription written in your name — not sold as a "research only" product with no oversight.

Know the difference

Prescribed Epithalon vs. supplements and grey-market vials — what's the difference?

The short answer: unregulated supplements make claims nobody checks, "research only" vials sold online carry no prescription, no pharmacy and no accountability, and a prescribed Epithalon is compounded by a licensed 503A pharmacy against a provider's order written for you.

	Oral supplement	"Research only" vial	Prescribed Epithalon (Rx)
What it is	An unregulated oral precursor	A vial sold without a prescription	Compounded Epithalon dispensed on a provider's order
Licensed provider reviews you	No	No	Yes — before anything is dispensed
Compounded by a licensed pharmacy	No	No	Yes — U.S. 503A
Your name on the vial	No	No	Yes
Dose set by a prescriber	No	No	Yes
Legal to sell for human use	As a supplement	No	Yes — by prescription

The simplest test of any peptide seller: is your name on the vial? A "research only" label means no prescriber reviewed you, no licensed pharmacy compounded it, and nobody is accountable for what is actually inside.

How it works

How does getting Epithalon actually work?

Three steps: answer a short set of medical questions, a licensed provider reviews them, and if they prescribe, a 503A pharmacy compounds and ships it.

Answer a few questions

A short private medical questionnaire — your history, current medications and what you are hoping to address. It takes a couple of minutes.

Meet your provider live

A provider licensed in your state reviews your answers online — no appointment, no waiting room. They decide whether Epithalon is appropriate.

Compounded & shipped

If they prescribe, a licensed U.S. 503A pharmacy compounds your vial and ships it discreetly, with your name on the label.

Who it's for

Who is Epithalon for?

It's for adults who want Epithalon prescribed and compounded properly rather than bought from a grey market. Whether it is appropriate for you is a decision for the provider who reviews your visit.

✔Interested in the longevity category

You have read about Epithalon in the context of cellular ageing and want it prescribed properly rather than bought from a grey market.

✔You want a real prescription

Reviewed by a licensed provider, compounded by a 503A pharmacy, dispensed with your name on the vial.

✔You want the dosing decided for you

You would rather a prescriber set the amount and schedule than follow a protocol from a forum.

✔You prefer an injectable

Epithalon is compounded as a subcutaneous injection. There is no oral or topical form.

✕When it's not the right fit

Most Epithalon research is preclinical and from a small number of groups. It is a compounded preparation, not an FDA-approved medication, has not been shown to treat or prevent any disease, and compounded drugs are not reviewed by the FDA for safety or effectiveness. If you are pregnant or breastfeeding, have an active cancer diagnosis, or have significant kidney or liver disease, tell your provider in your answers. New or unexplained symptoms should be evaluated by a clinician rather than self-treated.

Using it & safety

Forms & how it's taken

Injection: Compounded as injection.
Supplied as: 10mg. Which one you receive is part of the prescription.
Dose & schedule: Set by your prescriber. Follow the directions on your label.
Supply: 1-month or 3-month. Three months costs less per month.

Safety & side effects

⚠ Evidence in humans is limited

Reported effects are most often related to the injection itself or to infusing too quickly. They can include:

Redness or soreness at the injection site
Drowsiness
Headache
Changes in sleep pattern

Tell your provider about every condition and medication before starting, including pregnancy or breastfeeding. Stop and seek care for signs of an allergic reaction — rash, swelling of the face or throat, or difficulty breathing. For emergencies call 911.
