What is Epitalon?
Short answer
Epitalon is a synthetic peptide of four amino acids, Ala-Glu-Asp-Gly, modeled on epithalamin, an extract of the pineal gland. It was developed by one research program in St Petersburg, and the published evidence is a 2003 in vitro study in human fetal fibroblasts plus that program's own animal work; no independent human trials exist. In the US it is prescribed only as a compounded medication, and compounded medications are not FDA-approved.

Where does Epitalon come from?
Epitalon is a synthetic peptide of four amino acids, alanine, glutamic acid, aspartic acid and glycine, written Ala-Glu-Asp-Gly or simply AEDG. It was designed as a short, defined stand-in for epithalamin, an extract of the pineal gland, the small gland in the brain best known for producing melatonin. The idea was to replace a variable extract with a single sequence that could be made and studied consistently.
Epitalon comes from one research program in St Petersburg, Russia, and nearly everything published about it traces back to that group. The spelling varies: Epithalon and Epithalone appear in the journal literature, while Epitalon is the spelling used on US prescriptions and in this catalog. They are the same compound. As prescribed it is fully synthetic; a compounding pharmacy assembles the four-residue sequence, and no gland extract is involved.
What has Epitalon been studied for?
Epitalon research is narrow, and its place in a cellular-health catalog should not suggest otherwise. Two published items stand behind it. The first is a 2003 in vitro study that examined telomerase activity and telomere length in cultured human fetal fibroblasts exposed to the peptide. Cells in a flask are not people, and a measurement made in culture says nothing on its own about what happens after an injection.
The second is a 2010 review in the journal Biogerontology, written by the originating program, that summarizes its own animal studies under the heading of peptide bioregulation. A group reviewing its own work is a legitimate source, but it is not independent replication. No independent human trial of Epitalon has been published, and any statement about lifespan or aging in people goes well beyond this evidence.
| Area | Type of evidence | What the studies describe |
|---|---|---|
| Telomerase and telomeres | In vitro study in human fetal fibroblasts, 2003 | Telomerase activity and telomere length measured in cultured cells |
| Animal studies | Review of one program's own work, 2010 | The program's animal experiments, framed as peptide bioregulation |
| Humans | No independent trials | No controlled human trial outside the originating program in the cited pool |
Get Epitalon prescribed, pre-mixed
How is Epitalon prescribed?
Epitalon is prescribed in the US as a compounded medication: a licensed provider writes a prescription for an individual patient after an online intake, and a licensed 503A pharmacy prepares it. Through Peptides.build it is prescribed as a subcutaneous injection and ships already reconstituted, with the concentration printed in mg/mL on the pharmacy label, so there is no powder to mix.
Epitalon is typically prescribed in short cycles rather than continuously. The length of a cycle, the gap between cycles and the dose are all set by the provider, and none of them is published here. It is not part of any blend in this catalog. It shares the Cellular Health hub with GHK-Cu, a copper-binding tripeptide with a separate literature centered on skin and connective-tissue remodeling; a provider may discuss either at intake, and the two are not interchangeable.
Is Epitalon FDA-approved or allowed in sport?
Epitalon is not FDA-approved for any use. When it is prescribed it is a compounded medication, and compounded medications are not FDA-approved: they are prepared for one patient on prescription and are not reviewed or approved the way mass-manufactured drugs are. The research behind it was published outside the US regulatory system, and nothing in that literature changes its status here.
Epitalon is not named on the World Anti-Doping Agency Prohibited List. The list's S0 category can cover non-approved substances, meaning compounds with no current approval for human therapeutic use, so not being named is not a clearance. Drug-tested athletes should check with their governing body before starting a cycle.
How are Epitalon doses measured?
Epitalon prescriptions are written in milligrams, and the volume drawn depends on the concentration of the vial. A pre-mixed pharmacy vial states that concentration in mg/mL on its label; a powder vial gets its concentration from the water added. The free Epitalon calculator on this site turns a prescribed dose and a label strength into units on a U-100 insulin syringe and shows how many doses a vial holds, which is useful for a compound prescribed in cycles. It performs arithmetic only and does not recommend a dose or a cycle length.
Prescribed Epitalon vs research peptides: what is different?
Prescribed Epitalon is not a research chemical. It is a prescription medication: a licensed US provider reviews your intake first, and a licensed 503A pharmacy compounds it for you by name. Vials sold online as “research use only” skip both steps. What you pay for here is that review, a pharmacy you can name, and a label that says what is in the vial.
A research seller’s certificate of analysis is a document the seller controls: it chooses the lab and the sample, and a PDF can be reused, edited or re-dated. No regulator checks it.
| Point | Prescribed through Peptides.build | Research use only |
|---|---|---|
| Access | Online intake reviewed by a licensed US provider; prescribed only when appropriate. | No prescription and no clinical review of whether it suits you. |
| How it's labeled | A prescription medication compounded for you by name. | Commonly sold labeled “research use only, not for human consumption.” |
| Who prepares it | A licensed 503A US compounding pharmacy under state and federal oversight. | Unregulated suppliers, often with no verifiable chain of custody. |
| Testing | Third-party tested. | Certificates of analysis are self-reported when provided at all. |
| Purity and identity | Prepared to a prescription for a specific patient. | Purity, strength, and even identity are unverified by any independent party. |
This compares two care models, not two products. Compounded medications are not FDA-approved, and we do not claim otherwise. What a prescription adds is a licensed provider deciding whether a protocol is appropriate for you and a licensed pharmacy preparing it. Read the full guide to research vs prescription peptides.
Epitalon FAQ
Is Epitalon the same as Epithalon?
Yes. Epitalon, Epithalon and Epithalone are spellings of the same tetrapeptide, Ala-Glu-Asp-Gly, which is also written AEDG. The spellings differ between publications and product listings, but they refer to one compound.
Is Epitalon a hormone?
No. Epitalon is a synthetic peptide of four amino acids. It was modeled on epithalamin, an extract of the pineal gland, but it is not a gland extract and it is not melatonin, the hormone that gland is known for.
Has Epitalon been tested in humans?
Not in independent trials. The cited evidence is a 2003 in vitro study in human fetal fibroblasts and a 2010 review of animal work by the program that developed the compound. A prescribing provider will discuss what that evidence does and does not establish.
Is Epitalon FDA-approved?
No. Epitalon is not FDA-approved for any use. In the US it reaches patients only as a compounded medication prescribed by a licensed provider and prepared by a licensed 503A pharmacy, and compounded medications are not FDA-approved.
Is Epitalon banned in sport?
Epitalon is not named on the WADA Prohibited List. The list's S0 category can cover non-approved substances, so the absence of a name is not a clearance, and drug-tested athletes should check with their governing body.
How does Epitalon differ from GHK-Cu?
Both sit in the Cellular Health hub, but they are unrelated peptides. GHK-Cu is a naturally occurring copper-binding tripeptide whose literature centers on skin and connective-tissue remodeling, much of it topical. Epitalon is a synthetic tetrapeptide with in vitro and animal data from one research program. Neither has human trials of the injectable form, and a provider decides whether either fits.
Epitalon through Peptides.build
A licensed US provider reviews a short online intake and decides whether a protocol is appropriate. A US 503A pharmacy prepares it already reconstituted, labels the concentration and ships it cold-chain. Dosing is set by the provider and is not published on this site.
