Is Epithalon legal to buy in the United States?

It is sold lawfully as a research chemical, a category covering sale and possession and explicitly excluding human use. No FDA-approved Epithalon or Epitalon product exists for any indication, so there is no supervised version to obtain instead.

Is Epitalon on the FDA Category 2 list?

No. It was nominated for the 503A bulks list, placed in category 2 under the interim policies, and then the nomination was withdrawn by the nominator. It appears on no current category list. Pages saying it is category 2 today are citing a snapshot that has moved.

Does the certificate prove Epithalon is safe?

No. It proves things about one batch of powder: 99.312% purity against a greater-than-98% specification, identity by LC-MS, 9.64 mg of net content against a 10 mg label, a passing endotoxin screen and no microbial growth. FDA's position is that it lacks the information to know whether the substance would harm a human. A clean certificate does not change that.

Why does the vial hold 9.64 mg instead of 10 mg?

Filling is done to a tolerance, here 10 mg plus or minus 10%, and this batch landed under the nominal figure rather than over it. It is inside specification. It also puts the real cost on that batch at $2.59 per milligram rather than $2.50, and you only know that because the vendor printed the measurement.

Does Epithalon interact with my GLP-1 medication?

There is no interaction data, because there are essentially no human pharmacology studies of the kind that would generate it. That is a reason for caution rather than reassurance. Pairing it with a GLP-1 is a marketing idea, not a clinical one.

What about the telomere claims attached to it?

They come largely from one research group and have not been replicated to the standard applied to approved medicines. A certificate tells you what is in the vial. Nobody can currently tell you what it does in a person.

Epithalon Where to Buy: Judge the Seller Before the Peptide

Summary: A buying framework for a four-residue Russian peptide with no approved medical route anywhere in the West, applied line by line to the single certificate published for it, including the row where the vial comes in under its own label.

This content is for informational purposes only and is not medical advice. Always consult a qualified healthcare provider before starting, changing, or stopping any medication.

Epithalon where to buy is a documentation question, because the market selling it publishes little else. No pharmacy can fill it and no prescriber can order it, so the only leverage a buyer has is what a seller will commit to in writing about the batch in the vial.

One thing before the criteria, since this is a GLP-1 site. Epithalon is not a GLP-1, not an incretin and not a weight-loss compound. It has no effect on gastric emptying, no weight-management indication anywhere, and nothing here is a reason to add it to a semaglutide or tirzepatide regimen. It appears on this site because readers keep meeting it in the same longevity conversations and deserve a straight answer about what it is.

What is actually in the vial

Epithalon is a synthetic tetrapeptide. Four amino acids, in the order Ala-Glu-Asp-Gly, and that is the entire molecule. PubChem registers it as CID 219042, formula C14H22N4O9, molecular weight 390.35, CAS number 307297-39-8 ^[3]. The short chain is part of why it is cheap to make and cheap to sell.

A spelling note, because it changes what your searches return. FDA and PubChem write Epitalon, without the h. The buying market writes Epithalon. They are not two compounds: PubChem carries both spellings against the same record, along with the sequence name Ala-Glu-Asp-Gly ^[3]. Expect a certificate and a regulator's page to disagree on the letter and agree on everything else, and run epitalon where to buy alongside epithalon peptide where to buy when you are checking a source, because the two spellings surface partly different sellers.

Provenance matters more than usual here. The compound came out of Russian work led by Vladimir Khavinson, synthesised as a defined four-residue stand-in for a pineal extract called epithalamin. Its reputation rests on research from that group: a 2003 report of telomerase activity and telomere elongation in cultured human somatic cells ^[5], plus companion papers making far larger claims about human ageing.

Report that and stop there. Those are claims from one group, largely published in Russian-language or Russian-affiliated journals and largely not replicated to Western standards. Nothing in that literature establishes that Epithalon extends human lifespan, and this page does not say that it does. Set it beside what this site normally covers, where a compound reaches a reader through pre-registered endpoints and independently scrutinised results. How retatrutide's trial programme was actually run is the useful comparison, not because the compounds are related, but because it shows what the evidence bar looks like when something clears it.

The regulatory position, which most competing pages state incorrectly

Search this compound and you will find pages announcing that Epitalon is "FDA Category 2" or "banned for compounding". Both are wrong, and the accurate version is more useful.

FDA sorts bulk drug substances nominated for compounding under section 503A into three categories. Epitalon appears in none of them. Read the current lists, updated May 14, 2026, and the name is simply absent ^[2].

Where it does appear is a different FDA page, in a table headed "Bulk drug substances nominated but withdrawn", which FDA introduces as substances "previously in category 2 of the interim policies" that "were withdrawn by the nominators" ^[1]. So the correct sentence is: Epitalon was nominated, was placed in category 2 while FDA evaluated it under the interim policies, and the nomination was then withdrawn. It sits on no category list at all today. Pages saying it is category 2 are quoting a snapshot that has since moved.

The company in that withdrawn table is instructive: seventeen substances sit in it, including BPC-157, MOTs-C, Selank acetate, Semax, TB-500 and CJC-1295 ^[1]. None of this is approval, and none of it is a safety finding either way. A withdrawn nomination means the question was asked and then dropped before anyone answered it.

The one sentence FDA has published about this compound

The withdrawn-nominations table records what FDA thought the risk was, and it is specific rather than boilerplate:

Read that as a shopping instruction rather than regulatory prose. Immunogenicity means an immune reaction to the material itself. The mechanisms FDA names are aggregation, where peptide molecules clump into structures the body reads as foreign, and peptide-related impurities, the truncated and modified versions of the sequence that synthesis leaves behind. Both are manufacturing problems, measurable on paper before you spend anything.

That converts a vague worry into three separate questions. Purity tells you how much of the powder is the intended sequence. Identity tells you it is the right sequence at all. Endotoxin tells you about pyrogen load, which no purity assay can see, because bacterial endotoxins are cell wall fragments that survive ordinary sterilisation and need their own test. Most of this market answers the first question, some the second, and very few the third.

Epithalon where to buy: the criteria, ordered by what their absence lets through

The order is deliberate. A seller can be excellent on the bottom rows and still be the wrong purchase if it fails the top ones.

Criterion	What its absence lets through	How you check before paying
Batch-specific certificate naming the lot	Site-wide paperwork describing material you will never receive	The lot on the PDF has to match the listing, then the vial when it lands
Purity against a printed specification	A bare percentage with nothing to fail against	Look for the requirement beside the result, not just the number
Identity confirmed by mass spectrometry	A cheaper or truncated sequence sold under the right name	An LC-MS identity line naming the compound tested
Measured net content, not just a label	A vial holding whatever the filler happened to dispense	A milligram figure with a tolerance printed next to it
Endotoxin result with a stated limit	Pyrogen load, invisible to purity testing	A named method, a numeric result and an acceptance limit
Microbial or sterility screen	Contamination in powder destined for solution	A no-growth result, ideally with incubation conditions stated
Elemental impurity screening	Catalyst and process metals left behind by synthesis	A metals table with a result for each element named
A named laboratory and a verifiable report	Self-issued paperwork, which proves nothing	A lab name, a report number and a route to confirm it exists
Domestic stock and a written refund policy	Customs risk, and recourse living in a support inbox	Published terms, plus a first tracking scan inside your country

None of this needs a chemistry background. It needs you to open a PDF instead of a landing page, which is the step almost nobody takes.

Running the list against the source this page links

We link Ascension Peptides and earn a commission if you buy through the card above, disclosed there and on our disclaimer page. That is a reason to run the checklist strictly rather than gently.

The product is Epithalon 10 mg, lyophilised powder, listed at $50.00 against a $69.99 original. The code PEPTIDEDECK takes it to $25.00, or $2.50 per milligram on the label. Stock is domestic, the listing is marked research use only, and buying 3, 5 or 10 vials takes 3%, 5% or 10% off list separately.

On the documentation rows, open the certificate rather than trusting this page ^[4]. It is a single-page report from Kovera Labs on batch 15-05260628, report KVR-2026-A36FF4, certified 23 May 2026, and it covers more ground than most of this market does:

Purity 99.312% by RP-HPLC on a C18 column with diode array detection at 214 nm, against a printed specification of greater than 98%. The specification sitting beside the result is the part that matters.
Identity confirmed by LC-MS, with the sample block listing formula C14H22N4O9 and CAS 307297-39-8, both matching the public record ^[3].
Net content 9.64 mg against a labelled 10 mg, specification 10 mg plus or minus 10%. Inside tolerance, under the label.
Endotoxin safety screen against a limit of 0.5 EU/mL or less: pass.
Microbial sterility screen: no growth.
Heavy metals: arsenic, cadmium, lead and mercury each negative.

The net content row is worth pausing on, because it is the only number on the document that works against the seller. A vial labelled 10 mg that assays at 9.64 mg still costs $25.00 with the code, so the honest per-milligram figure on this batch is $2.59, not $2.50. Nobody would have noticed if the certificate had stayed quiet. It is also the reverse of the neighbouring Selank lot, which assayed 12.29 mg into a 10 mg vial. Both directions say the same thing: the tolerance is real and the paperwork reports it either way.

The rows where this certificate is thinner than it first looks

Three qualifications, because a page presenting the above as a clean sweep would not be worth reading.

First, the endotoxin line reports PASS rather than a number, and does not name the method. Compare the same vendor's Semax batch, which reports a kinetic chromogenic LAL test run to USP Chapter 85, below 0.20 EU/mL against a 0.5 EU/mL limit, and which we went through row by row. A pass against a stated limit beats the silence most competitors offer. It is still weaker than a figure you can check yourself.

Second, the sterility line is a screen with no incubation period, temperature or method printed, and the heavy metals table reports "negative" per element rather than a concentration against a limit. Negative is reassuring. A number is checkable.

Third, all of it describes one batch. The vendor publishes one certificate for this compound, so if the batch on your vial does not match 15-05260628, you have no document until you ask for one.

Where the checklist leaves a realistic buyer

There is no supervised route to compare against. No US prescriber can write for Epithalon, because nothing is approved to prescribe, and no compounding pharmacy can legitimately prepare it, because the nomination that would have opened that door was withdrawn. That leaves a research-vial market and a checklist. For the criteria turned into an explicit weighting, see the scoring method on our best Epithalon source page.

Questions readers ask before ordering

Is Epithalon legal to buy in the United States?: It is sold lawfully as a research chemical, a category covering sale and possession and explicitly excluding human use. No FDA-approved Epithalon or Epitalon product exists for any indication, so there is no supervised version to obtain instead.
Is Epitalon on the FDA Category 2 list?: No. It was nominated for the 503A bulks list, placed in category 2 under the interim policies, and then the nomination was withdrawn by the nominator. It appears on no current category list. Pages saying it is category 2 today are citing a snapshot that has moved.
Does the certificate prove Epithalon is safe?: No. It proves things about one batch of powder: 99.312% purity against a greater-than-98% specification, identity by LC-MS, 9.64 mg of net content against a 10 mg label, a passing endotoxin screen and no microbial growth. FDA's position is that it lacks the information to know whether the substance would harm a human. A clean certificate does not change that.

It is inside specification. It also puts the real cost on that batch at $2.59 per milligram rather than $2.50, and you only know that because the vendor printed the measurement.
Does Epithalon interact with my GLP-1 medication?: There is no interaction data, because there are essentially no human pharmacology studies of the kind that would generate it. That is a reason for caution rather than reassurance. Pairing it with a GLP-1 is a marketing idea, not a clinical one.

Epithalon where to buy comes down to which seller will show you its work. Most of this market prints a purity percentage and nothing behind it. The certificate checked here runs five tests, prints specifications beside results, and includes one measurement that costs the seller money. That is not a safety guarantee and should not be sold to you as one. It is more than the alternatives show, and every line can be checked before you spend anything.
