When you buy epithalon peptide the thing that turns up is smaller and duller than the marketing around it. A glass vial, a red cap, a silver crimp, and a scatter of white lyophilised powder that a kitchen scale could not weigh. Everything you can verify about that vial before it arrives is on one certificate, and most of it is arithmetic.
Key takeaways
- The product is lyophilised powder, not a solution. One SKU, 10 mg per vial, sold singly or as a ten-vial kit, and the certificate records a red cap and a silver crimp so the vial in your hand is checkable against the document.
- Epithalon is a synthetic tetrapeptide of four residues, Ala-Glu-Asp-Gly, molecular weight 390.35. It is not a heptapeptide like Selank or Semax and not a fifteen-residue sequence like BPC-157, so do not carry assumptions across from those pages.
- The certificate for batch 15-05260628 measures net content at 9.64 mg against a 10 mg label. That is inside the stated tolerance of 10 mg plus or minus 10 percent and it is under the label, which is the rarest kind of number a vendor prints.
- The dry format is why sterility and endotoxin results matter. FDA's stated concern with this compound is immunogenicity from aggregation and peptide-related impurities, and those are properties of the powder rather than of the vendor's website.
- Nobody sells this as a training compound. The vendor's own copy is about cellular ageing and telomere biology, so a lifter buying a vial is buying an anti-ageing claim rather than a performance one.

The cap and crimp colours are worth noticing, because they are the only line on the document that you can check with your eyes rather than with a calculator. A certificate that describes the physical vial, and a vial that matches the description, is a small piece of evidence that the document and the object belong together. It is not proof. It is one more thing that would have to be faked.
There is one certificate for this compound on this store, not two. Some listings on the same site carry an older document beside a newer one, and a buyer who opens only the linked PDF can miss the weaker of the pair. Here there is a single report, so the only question is whether the batch number on your vial matches it.
The molecule on that label, precisely
Epithalon is a synthetic tetrapeptide. Four amino acids, in the order alanine, glutamic acid, aspartic acid, glycine, usually written Ala-Glu-Asp-Gly or abbreviated AEDG. It is listed on PubChem as CID 219042 with the molecular formula C14H22N4O9 and a molecular weight of 390.35, and the certificate carries the CAS number 307297-39-8.
Spelling first, because it changes what your searches return. FDA and PubChem write Epitalon. The buying market, including this vendor, writes Epithalon. They are the same molecule and not two related compounds, so a search that comes back empty on one spelling is worth repeating with the other.
Four residues is genuinely small. BPC-157 runs to fifteen, and Selank and Semax are heptapeptides at seven, so a molecular weight of 390.35 puts Epithalon closer to a large drug molecule than to what most people picture on hearing the word peptide. That matters in one practical way: short sequences are cheap to synthesise, which is much of why a 10 mg vial sells for $50.00 rather than several hundred. A low price on a four-residue peptide is normal, not a warning sign. Reading the sequence off the label before trusting the marketing is the same check we ran in what a MOTS-c label does and does not tell you.
The origin is worth having straight, because vendors compress it. Epithalon was developed in Russia by Vladimir Khavinson's group as a synthetic version of a fraction of pineal gland extract called epithalamin. The synthetic tetrapeptide is what you can buy. The extract is not the same thing, and claims made about the extract get quoted as though they were made about the peptide.
What "10 mg" means when the certificate says 9.64 mg
Most peptide certificates never answer this question at all. They report purity as a percentage and stop, which tells you what fraction of the powder is the peptide and nothing whatsoever about how much powder is in the vial. Purity and quantity are separate measurements, and a 99% pure vial containing half the labelled mass is still half a vial.
This certificate reports both. Purity comes in at 99.312% against a greater than 98% specification. Net content comes in at 9.64 mg against a specification of 10 mg plus or minus 10 percent, which sets an acceptance window from 9.0 mg to 11.0 mg. The result passes, and it sits about 3.6 percent under the label.
Read that carefully rather than either way it will be spun at you.
It is not a defect. A tolerance is not decoration; a fill process that lands inside a declared window is a fill process working as declared, and lyophilised fills of a few milligrams are difficult to hit exactly.
It is also not nothing. If you paid $25.00 for the vial, dividing by the label gives $2.50 per milligram and dividing by what was weighed gives $2.59. Both figures are honest, and only one of them is flattering. The full arithmetic sits on the Epithalon price page.
What it mostly is, though, is a document behaving well. A vendor that prints a number slightly against itself, rather than rounding it up to the label, is telling you something about how it treats paperwork it does not have to publish. The same store's Selank certificate for lot 29-01260229 reported 12.29 mg against a 10 mg label and the arithmetic ran the buyer's way instead. Two lots, two directions, both printed. Reading the measured quantity rather than the printed label is the same habit we argued for in what is actually in a BPC-157 vial.
Why the dry format is the part that matters
Lyophilisation, or freeze-drying, is not a presentation choice. Peptides in solution degrade, and a short sequence sitting in water at room temperature is on a clock. Removing the water stops most of that, which is why nearly everything in this market ships as powder.
The format is also the reason the microbiological lines on a certificate deserve attention. A lyophilised powder is not sterile by virtue of being dry, and it carries no preservative. Whatever is in the vial when it is sealed is what is in the vial when it is opened.
FDA's stated concern with this compound points at exactly this territory. The agency writes that compounded drugs containing epitalon may pose a risk for immunogenicity for certain routes of administration due to the potential for aggregation and peptide-related impurities, and that it has not identified safety-related information regarding epitalon for the proposed route of administration. Aggregation and peptide-related impurities are properties of the material, and they are what purity, identity, endotoxin and sterility testing are built to characterise.
On batch 15-05260628 that scope is present: identity confirmed by LC-MS, an endotoxin safety screen passing against a limit of 0.5 EU/mL, a microbial sterility screen returning no growth, and heavy metal screening with arsenic, cadmium, lead and mercury all negative. Two caveats belong with it. The endotoxin result is recorded as a pass against the limit without naming the compendial method behind it, where some certificates in this market name a kinetic chromogenic LAL test run to USP Chapter 85 and print the measured figure. And a sterility screen is a screen. Neither line converts a clean batch into evidence that the compound is safe in a person, which is the separate thing FDA is saying it does not know. The tradeoff between format, testing and what you can actually verify runs the same way for a very different molecule in buying NAD+ as an injection.
Storage, before and after water goes in
The vendor states its own storage position on the product page, and it is the conventional one for this class: store lyophilised peptide at minus 20 degrees Celsius in a dry, dark place; once reconstituted, store at 4 degrees Celsius and use within 28 days; avoid repeated freeze and thaw cycles.
Two things follow. The clock changes character the moment water is added: dry powder in a freezer has a long horizon, the same material in solution in a fridge has a short one, and the 28 day figure is the vendor's limit rather than ours. And that is why a ten-vial kit is a different purchase from ten times one vial, because ten sealed vials keep their own clocks.
We do not publish reconstitution volumes, concentrations or protocols here, and neither does the seller: the store states plainly that as a research chemical company it is not permitted to discuss reconstitution or dosage. If you need the unit arithmetic, Peptide Dosage covers it at the Epitalon dosage page with a converter at the Epitalon calculator, under the market's spelling variant.
What the vial is actually being sold on
Worth ending here, because it is the part the product photograph hides. Nothing about this listing is aimed at training. The vendor's own description frames Epithalon around cellular ageing, telomere biology and senescence research. There is no strength claim, no hypertrophy claim, no recovery claim and no sports outcome anywhere in the copy, which means there is nothing of that kind to evaluate.
So be plain about the transaction. A lifter in their forties or fifties buying this vial is buying an anti-ageing claim. That claim traces largely to Russian-language work from a single research group around telomerase activation and longevity, and it has not been replicated to the standard a Western regulator would require. You can read what is claimed and note who claims it. Treating it as established, or expecting it to show up in a training block, is not supported by anything on the certificate or anywhere else.
Frequently asked questions
What form does epithalon 10mg arrive in?
Lyophilised powder in a sealed glass vial with a red cap and a silver crimp, sold either singly or as a kit of ten vials. It is not a solution and it does not arrive ready to use. The certificate records the same form and vial description, so the object and the document can be checked against each other.
How many amino acids is epithalon?
Four. It is a tetrapeptide with the sequence Ala-Glu-Asp-Gly, formula C14H22N4O9 and molecular weight 390.35, listed on PubChem as CID 219042. It is not a heptapeptide like Selank or Semax and not a fifteen-residue peptide like BPC-157.
Is 9.64 mg in a 10 mg vial a short fill?
It is under the label and inside the specification. The certificate states a tolerance of 10 mg plus or minus 10 percent, giving a 9.0 mg to 11.0 mg window, and 9.64 mg passes. It is about 3.6 percent below the labelled quantity, which is worth knowing and worth crediting the vendor for publishing.
Why is epitalon spelled two different ways?
FDA and PubChem use Epitalon. The peptide market, including this vendor, uses Epithalon. It is one molecule with two spellings, so search both if a query comes back empty, and treat documents under either spelling as referring to the same compound.
How should a lyophilised epithalon vial be stored?
The vendor states minus 20 degrees Celsius, dry and dark, for the sealed powder, then 4 degrees Celsius and use within 28 days once reconstituted, avoiding repeated freeze and thaw cycles. That is the seller's own stated position rather than a protocol from us, and it is the reason a ten-vial kit behaves differently from one large mixed volume.
Does a clean certificate mean the peptide is safe to use?
No. The certificate characterises the material: what it is, how pure it is, how much is there, and whether the endotoxin and sterility screens passed. FDA's position is that it lacks the safety information to know whether epitalon would cause harm if administered to humans, and no laboratory report can supply human data.
