Epithalon vs epitalon: the same Russian tetrapeptide spelled two ways, how it differs from epithalamin, prices under either name and COA name checks.
Epithalon (epitalon) is a tetrapeptide studied for telomerase activation and aging biology.

When FDA's compounding advisory committee voted 7-4 on 24 July 2026, the substance on the agenda was listed as epitalon, while US research vendors such as Real Peptides sell it as "Epithalon Peptide (10mg)" at $24.00. The two names point to one compound. The epithalon vs epitalon question is a spelling question, and the answer is short: same peptide, two ways of writing a Russian name in English letters.
Even today, customers still see this distinction as relevant since the different searches, catalogues, certificates, and regulatory paperwork don’t use the same format. This page will trace the origin of each spelling and provide you with tips on how to identify the product you want to compare. In all cases, the peptide is not FDA-approved and is sold exclusively for research purposes.
Concerning epithalon versus epitalon, the brief version is that both terms are English terms for the same tetrapeptide that is developed in Russia, which is a combination of four amino acids. There is no spelling that is more correct than another.
The word "th" is taken from the Greek word epithalamus which is part of the brain which contains the pineal gland and is where the original research began. The letter "t" comes more closely to the one used in Russian because there is no "th" sound in Russian and scientific reports in Russian use both. You can also see epithalone and epitalone once in a while which are a synonym of the same word again.
The use of the word divisions is mostly determined by the target audience and knowing the pattern is beneficial when performing searches. We discuss what we see in the respective sources.
| Source | Spelling used |
|---|---|
| Real Peptides listing | Epithalon Peptide (10mg) |

| July 2026 FDA panel coverage | Epitalon, often with epithalon alongside |

From what we have learned it seems that in the United States, research companies prefer to use “epithalon” while scientific literature and regulatory texts talk about “epitalon.” If you rely on a single spelling, you might miss some important information.
The genuine name issue refers to the term epithalamin. Epithalamin describes the extract in its original form which has been derived from animals' pineal glands by Russian scientists in their experiments. Epithalon refers to the shortened type of this synthetic polypeptide that was synthesized at a later time.
The two get mixed up in forum posts and on some product pages. That matters because some of the older human studies in Russia used the extract, not the synthetic peptide, and results from one cannot simply be credited to the other. When you read a claim, check which substance the study used. We sort the research by study type on our epitalon benefits page.
Epithalon and epitalon yield the same products, so it makes sense to check the prices per mg as both appear in the search results. The price for epithalon on the Real Peptides website is $24.00 for 10 mg, which equals $2.40 per mg. Peptide God sells it for $29.95, but there is no vial size given in our system, so it will have to be checked on the product page before calculating the cost per mg of the peptide.
Shipping thresholds differ too: free US shipping over $100 at Peptide God, over $250 at Real Peptides. Peptide God also offers 30-day free returns. The full comparison, with shipping math, is on our epithalon price per mg page.
There is a possibility that a certificate of analysis has a somewhat different spelling than what you have on the product page, which is not an issue in itself. Instead you must check if the document actually states the correct substance and the same batch of it.
If the COA names epithalamin, or a different peptide altogether, ask the vendor before using the product in any research. A spelling difference is fine. A different substance is not. Our buy epithalon page covers COA checks in more depth.
Since authorities treat both names as one and the same, the ruling regarding epitalon is pertinent to epithalon as well. This is important now since the ruling by the panel regarding epithalon, which will take place in July 2026 if FDA decides to move forward with it, will apply to this substance no matter what spelling is adopted.
The flip side is the same. The recommendation is non-binding, and as of the July meeting the peptide had not been added to the 503A bulks list, whatever it is called. A listing that uses the regulatory spelling is not more approved than one that does not. We follow the next steps on our FDA 2026 page.
