Epithalon, prescribed — not just shipped.

A synthetic tetrapeptide derived from a pineal-gland peptide, studied for telomerase activity and circadian signaling, and sold only as a single month.

Coming soon

Promise is moving to a new prescriber network. Visits are paused while we make the switch — leave your email on any treatment page and we'll tell you when they reopen. A licensed provider will still review every request, and not everyone qualifies.

You are on the list. We will email you if Epithalon becomes available — and nothing else. Joining is not a medical request, and no prescription has been issued.

That did not go through. Check the address and try again.

We store your address and which treatment you asked about, and use it only to tell you if Epithalon becomes available. Joining is not a medical request and no prescription is issued from this form.

How it works once Epithalon is available

  1. 1

    Share your health history

    Every treatment gets its own online clinical questionnaire — your history, medications, and goals.

  2. 2

    A licensed provider reads it

    A real person goes through your history and takes the time to get it right before anything is decided.

  3. 3

    They prescribe — or they don't

    If a treatment isn't right for your history, you'll hear that plainly. That review is the whole point.

  4. 4

    Your pharmacy compounds it

    Made for your prescription by a licensed U.S. pharmacy and shipped in temperature-safe packaging.

  5. 5

    You choose whether to continue

    Your care team checks in after it arrives. Adjust with your provider, or cancel at any time.

A four-amino-acid pineal peptide

Epithalon is a synthetic tetrapeptide derived from epithalamin, a pineal-gland extract. Research interest centers on telomerase activity and on circadian and pineal signaling.

A single month, not a subscription

It is sold as a single month only, with no subscription or 3-month option; the prescribing provider sets the protocol.

Prescribed, never simply supplied

A licensed provider reads your history, decides whether Epithalon fits it, and sets the protocol.

In brief.

Epithalon is one of the older ideas in longevity research and one of the least settled. It is a synthetic peptide of four amino acids, derived from a pineal-gland extract, and it is studied for its effect on telomerase and on the pineal signaling that governs circadian rhythm. It is also sold differently from everything else in the catalog: as a single month, without a subscription or 3-month option.

Promise offers injectable and nasal spray formats, both sold as a single month. A licensed provider reviews your health history and prescribes only when treatment is appropriate for you.

What Epithalon is

Epithalon is a tetrapeptide — alanine, glutamic acid, aspartic acid, glycine — synthesized as a simplified version of epithalamin, an extract taken from the pineal gland. The pineal gland is the small structure that produces melatonin and helps set the body's day-night timing, and the original research programme was built around the idea that peptides from that gland influence how the system ages.

It belongs to our anti-aging and longevity category alongside GHK-Cu, though the two come at the subject from completely different directions. GHK-Cu is studied in connective tissue and copper transport; Epithalon is studied at the level of cellular replication and biological timing.

What the research does and does not show

The laboratory case is coherent. Cell and animal studies have examined Epithalon's influence on telomerase, the enzyme that maintains the protective caps on the ends of chromosomes, and on markers tied to pineal and circadian function. That is a real, describable mechanism, and it is why the compound keeps resurfacing in longevity discussion.

The human case is thin, and we would rather say so than imply otherwise. Most clinical work on Epithalon comes from a small number of studies run in Russia over several decades, much of it published in Russian, with small participant groups and limited independent replication. Nothing here is settled science. A described mechanism is not an outcome, and interest in a compound is not evidence about it.

Why it is sold as a single month

Epithalon is offered as a single month only, not as a subscription or a 3-month supply. The provider who evaluates you sets the protocol; this page does not publish a schedule.

If your provider decides at some later point that another month is appropriate, that is a fresh clinical decision made at a fresh visit, not an automatic renewal running in the background.

How Epithalon is prescribed

Everything starts with an intake questionnaire built specifically for this compound: your health history, current medications, and what you are trying to address. A licensed provider reads it. If Epithalon is a reasonable fit for your history, they write the prescription and set the protocol. If it is not, they decline, and they will say so.

Given how limited the human evidence is, that gate carries more weight here than usual. A provider weighing Epithalon is weighing a thin clinical file against your particular chart, and for many people the reasonable answer is a different compound or none at all.

What treatment looks like

If you are prescribed, your medication is compounded and dispensed by a licensed U.S. pharmacy, and shipped in discreet, temperature-safe packaging. Dosing is not a number to find online; your provider sets the protocol from your evaluation, and you follow theirs for the length of the course.

Your care team checks in afterward. There is no automatic next shipment and no plan running quietly in the background — what happens next is a conversation. Epithalon sits on top of the fundamentals, particularly sleep, rather than standing in for them. It is a support for the promise you already made to yourself, not a replacement for the work.

Common questions

What is Epithalon?

Epithalon is a synthetic peptide of four amino acids — alanine, glutamic acid, aspartic acid, and glycine. It was derived from epithalamin, an extract of the pineal gland, and research interest centers on telomerase activity and on the pineal gland's role in circadian rhythm. It is offered as a single month rather than as a recurring treatment plan.

Is this real Epithalon, or a research chemical?

A real prescription. Epithalon on Promise is prescribed by a licensed provider after a review of your health history and compounded for you by a licensed U.S. pharmacy. It is not a product labeled for laboratory use.

Does starting a visit guarantee a prescription?

No. A licensed provider reviews every Epithalon request and prescribes only when it is appropriate for you. If it isn't, you'll be told plainly — that review is the point.

Why is Epithalon sold as one month instead of a subscription?

Epithalon is sold as a single month only, with no subscription or 3-month option. Your provider sets the protocol after reviewing your history. If a provider later considers another month appropriate, that is a new clinical decision rather than an automatic renewal.

Do I need a prescription for Epithalon?

Yes. Epithalon is available through Promise only by prescription. You complete an intake questionnaire, a licensed provider reviews your health history, and they prescribe only when treatment is appropriate for you.

Is Epithalon FDA-approved?

No. Epithalon is not FDA-approved. It is a compounded medication, and compounded medications are not reviewed by the FDA for safety, effectiveness, or quality. It is prepared by a licensed U.S. compounding pharmacy against a prescription written for you specifically, after a licensed provider has reviewed your health history.

How strong is the evidence behind Epithalon?

Weaker than the conversation around it suggests, and it is worth saying so plainly. Most of the human work comes from a small number of studies conducted in Russia over several decades, much of it published in Russian, with small groups and methods that have not been widely replicated elsewhere. The laboratory and animal work on telomerase and pineal signaling is more consistent, but it does not tell you what happens in a person. Epithalon is a compound with an interesting mechanism and a thin clinical file, which is exactly why the decision belongs to a clinician who knows your history.

How is this different from Epithalon sold online?

Epithalon sold online without a prescription is usually labeled for laboratory use, with no provider, no pharmacy, and no one accountable if something goes wrong. Promise works the way medicine is supposed to: a licensed provider decides, a licensed U.S. pharmacy compounds your prescription, and a care team follows up.
