Endoluten dosage and evidence
Written by Aaron CuhaReviewed Sep 2026
The short answer
Endoluten is a pineal gland capsule sold on the long-life claims of two other products.
Evidence grade for Endoluten: Preliminary. The rule: studied in people, but no published study has had people take it. The sum on this page: 3 human studies where nobody was given it. A grade counts how much has been done to people, not whether it works.

In plain English
In plain English, from Aaron
This is how I would explain it to a friend. The evidence, with the numbers, is further down the page.
Endoluten is a capsule sold for sleep, hormones and a longer life. It is meant to come from the pineal gland. Search for it in the medical database and you get zero papers. Zero. Every big number used to sell it belongs to two other substances, and neither one is what is in the bottle.
What people take it for
- Sleeping better and getting the body clock back in order.
- Living longer, because the marketing leans hard on that.
- Hormone balance in your 60s and beyond.
- Feeling sharper and less worn down.
What studies in people showed
Three names get mixed together here, so keep them apart. Epithalamin is a shot made from cow pineal glands. Epitalon is a lab made peptide built from it. Endoluten is a capsule with no research under its name. All the famous numbers are from epithalamin. In animals it raised average life span by 11 to 31 percent, though in one group of mice it did nothing. In 266 older people followed 6 to 8 years, deaths dropped by about 1.6 to 1.8 times. In a 12 year study of older heart patients, deaths were 28 percent lower. Those are real published numbers. They were all produced by the institute that sells the product, nobody outside has repeated them, and there is no registered trial for anything in this family. A separate pineal shot called Pineamin raised a melatonin marker 1.9 times in 55 older people, with no control group.
What people report
Reports, not study results
The good
- Better sleep is the most common report by a wide margin.
- Vivid dreams in the first week or two.
- Some people say they wake up at a steadier time.
- The capsule course is short, so it is easy to try and stop.
The bad
- Headaches and grogginess in the first few days, reported often on forums.
- Plenty of people report nothing at all.
- No safety data exists. Not one study in this family lists side effects, which means nobody looked.
- Nobody has tested what is in the capsule, so you cannot know if it matches the shot used in those studies.
Where these come from: Sleep and dream reports come from peptide forums and vendor pages. The death and life span numbers come from published Russian studies of the injectable gland extract, not of this capsule.
My bottom line
Those mortality numbers are real papers, and they were written by the people selling the product, with nobody else checking. Buying a capsule and quoting a study done on a cow gland shot is the mistake almost everyone makes here, and I would not spend money on it.
An opinion, not a finding. I am a coach, not a doctor.
What it has been measured to do
Measured in people
Goals Endoluten has been tested for in people, biggest studies first. We count only what the studies on this page say, so the real numbers may be higher.
- Living longerno headcount stated · 1 study
What people using it report
Real people telling you what happened to them. Nobody checked it, and the people who post are not a fair sample, so it cannot prove anything works. It is still the best guide on this page to what people actually do with Endoluten, what they expect, and what goes wrong. The full account, including the negative reports, is below.
33 of the 36 indexed goals have no study of any kind behind Endoluten
No study in people, animals or cells on this page reports a result for these. That does not prove Endoluten does nothing for them. It does mean anything you have heard about Endoluten and one of these did not come from a study cited here.

What is Endoluten?
Endoluten is a pineal gland capsule sold on the long-life claims of two other products. A PubMed search for Endoluten finds zero papers. Every lifespan and death-rate number tied to it came from epithalamin, an extract of cow pineal gland, or from epitalon, a lab-made peptide. Nobody has shown that either one is what is in the capsule.
Endoluten is one of the most heavily marketed products in the Khavinson shop line. It is sold as a pineal gland mix for sleep, body rhythms and long life. Search PubMed for the name and you get nothing. Zero papers.
The numbers used to sell it come from two related but different products. That difference is the whole story of this page.
Epithalamin is an extract of cow pineal gland. It is the parent product, and almost every long-life claim in this family comes from it. In people, one report followed 266 older adults for 6 to 8 years. Some were given epithalamin, alongside thymalin, a thymus gland extract. The authors say deaths fell 1.6 to 1.8 fold in the epithalamin group. In a separate 12-year study of older people with heart disease, there were 28 percent fewer deaths in the epithalamine group than in the comparison group.
In animals, epithalamin raised average lifespan by 11 to 31 percent in fruit flies, mice and rats.
Epitalon is a lab-made peptide of four amino acids, Ala-Glu-Asp-Gly, designed from epithalamin. It is one defined molecule, and it has its own separate research.
Endoluten is neither one. It is a capsule sold in shops. No published test shows that what is in it matches epithalamin, and you cannot tell a cow gland extract from a label. If you quote the epithalamin numbers, you are quoting a Russian gland extract given as shots, in studies run by the group that made it. You are not quoting a capsule bought online.
How does Endoluten work?
How it would work is borrowed, not shown. In people, a separate Russian pineal product called Pineamin was given to 55 older patients. A melatonin marker in their urine rose 1.9-fold. Everyone got the product, and there was no comparison group. That is the most direct test of pineal function in the family. In rats, epithalamin was reported to raise melatonin, the sleep hormone. In rats and flies, it was reported to slow damage from free radicals, the unstable molecules tied to aging. The authors of the 1998 lifespan paper thought this was how it helped animals live longer. None of this work used Endoluten.
What have studies in people found about Endoluten?
There is human data in this family, and none of it used Endoluten. Two long studies of epithalamin, a cow pineal extract given as shots, report big drops in deaths. One small study of a third pineal product reports a rise in a melatonin marker in urine, with no comparison group.
- 266 older adults followed for 6 to 8 years, given epithalamin in the first 2 to 3 years: the authors report deaths 1.6 to 1.8 fold lower than the comparison group, and 2.5 fold lower with thymalin added.
- A 12-year study of older patients with heart disease: 28 percent fewer deaths in the epithalamine group, and heart deaths 2-fold lower.
- 55 older patients given Pineamin, a separate Russian pineal medicine: a melatonin marker in their urine rose 1.9-fold. Everyone got it, and there was no comparison group.
- Zero published studies of Endoluten itself, under that name, in people or animals.
- Zero registered clinical trials for any product in this family on ClinicalTrials.gov, the US trial registry.
What this does not tell you: Three problems, and each one is enough on its own. First, it is the wrong product. The studies used cow gland extracts given as shots, and a Russian medicine. They did not use a shop capsule you swallow, and nobody has shown the capsule holds the same stuff. Second, nobody else has checked. The death studies come from the institute that made the extracts, and no outside team has repeated them. Third, how the studies were run. People were followed for 6 to 8 years but only treated in the first 2 to 3, and deaths were what got counted. In that kind of study, how people were put into groups and tracked decides the result. The short English summaries do not give that detail.
What do people who took Endoluten report?
This is what real people say happened to them, good and bad. Nobody measured it. A report cannot tell a real effect from the lift people get just from expecting it to work, from a diet or training change made at the same time, or from what was really in the vial. We still put it near the top. It is the next best thing to a study in people: what happens when real people use it, including what goes wrong.
- Two routes are discussed and people choose between them explicitly. The oral capsule is preferred by those who do not want to inject, and daily injected epithalon is the alternative described by people willing to.
- The schedule described is one to two capsules morning and evening taken as a course of about a month, with some people saying they instead take a smaller amount continuously rather than in courses.
- Cost is the obstacle raised most often, with figures in the hundreds of dollars for a single oral course, and sourcing is described through Russian suppliers, which brings the usual questions about what is actually in the capsule.
- What people report is skin appearance and general wellbeing rather than anything they can measure, with one long individual account describing kidney markers changing across years of daily use.
- The negatives here are mostly about the evidence rather than about harm. The number of genuine first-hand accounts is very small, the people writing them say themselves that they were running senolytics and other interventions at the same time and cannot separate the effects, and side effect reports are essentially absent. In a sample this small that is an absence of data, not a safety finding.

The state of the research
This page keeps three names apart because the marketing does not. Epithalamin is an extract of cow pineal gland, and it holds the lifespan and death data. Epitalon is a lab-made peptide, Ala-Glu-Asp-Gly, designed from it, with its own separate research. Endoluten is a capsule sold in shops, with zero published papers under its name. Buying the third and quoting the first is the standard mistake in this category.
Every peptide in the Khavinson family shares one problem, and it is not the chemistry. Not one of them has a registered clinical trial. The US trial registry, ClinicalTrials.gov, shows zero studies for epitalon, thymalin, cortexin, retinalamin, prostatilen and epithalamin. The same search finds studies for ordinary drugs. Almost all the research sits in three journals: Advances in Gerontology, Bulletin of Experimental Biology and Medicine, and Vestnik Oftalmologii. Most of it is in Russian, with only a short English summary. Most of it comes from the St. Petersburg Institute of Bioregulation and Gerontology, or from Anisimov's group in the same city. No outside team has repeated any of the lifespan claims. None of the study summaries we found report side effects. These Russian papers do not usually track safety. So read the silence as missing data, not as proof it is safe.

This chart would show how the effect changes as the amount goes up. For this compound, nobody has measured that in people. So we leave it empty. We will not borrow an animal chart and pretend it works the same in people.

- None on file
Half-life as stated on file: Not established for this product. It is a mixed preparation taken by mouth, so a single half-life would not describe it even if one had been measured.
No amino acid sequence is on file for Endoluten, so none is drawn rather than guessed from a name.
The studies we cite
- Study in people2003Peptides of pineal gland and thymus prolong human life.
This is the study the whole thymalin and epithalamin story rests on, and it is not built to carry it. 266 older people were followed for six to eight years, with injections only in the first two or three. The authors report deaths running between a third and three quarters lower, depending on the preparation and the group. Here is the problem. The institute reporting it invented the preparations, and nobody outside has repeated it. These were injected gland extracts, not the capsules sold today.
266 elderly and older persons followed 6 to 8 years, with the preparations given only in the first 2 to 3 years. The authors report mortality falling 1.6 to 1.8 fold with epithalamin, 2.0 to 2.1 fold with thymalin, and 2.5 fold with both together, and 4.1 fold in a subgroup given both annually for 6 years. This is the single largest human claim in the family. It is authored by the institute that developed the preparations, it uses the injectable gland extracts rather than any retail capsule, and no independent replication has been located.
- Study in people2006Geroprotective effect of epithalamine (pineal gland peptide preparation) in elderly subjects with accelerated aging.
A second study from the same institute, reporting the same kind of result, with the same piece missing. Older patients with heart disease were followed for 12 years. The authors say deaths were 28 percent lower on epithalamine, and that heart deaths, heart failure and chest infections each happened about half as often. The authors say people were put into groups by chance. It is once again their own preparation, in their own study, and no outside team has repeated it.
A 12-year study in elderly patients with coronary disease and accelerated cardiovascular aging. Deaths in the epithalamine group were 28 percent lower than control, cardiovascular mortality was 2-fold lower, and the incidence of cardiovascular failure and respiratory disease was 2-fold lower. Reported as randomised by its authors. Again the institute's own work, again the injectable extract, again no outside replication.
- Study in people2017[Pineamin increased pineal melatonin synthesis in elderly people].
The one measured effect in people is real, and it belongs to a different product. 55 older patients were given Pineamin, a Russian pineal preparation that is neither epithalamin nor epitalon. A marker of melatonin in their urine came out nearly twice as high afterwards. But everyone got the drug. There was no comparison group, so there is no way to know what those readings would have done on their own.
Pineamin, a registered Russian pineal polypeptide preparation distinct from both epithalamin and epitalon, raised urinary 6-sulfatoxymelatonin excretion 1.9-fold in 55 elderly patients. Uncontrolled, before and after, no comparison group. This is the closest thing in the family to a measured pineal effect in people, and it is a different product again.
- Review of studies2025Overview of Epitalon-Highly Bioactive Pineal Tetrapeptide with Promising Properties.
A review that lays out the family tree. Epitalon, a lab-made peptide, was designed from epithalamin, a cow pineal extract. The shop capsule does not appear anywhere in the research.
States explicitly that the synthetic tetrapeptide epitalon, Ala-Glu-Asp-Gly, was designed from the bovine pineal extract epithalamin. This is the paper that establishes the family tree: extract first, synthetic tetrapeptide second, retail capsule nowhere in the literature.
- Animal study1998Pineal peptide preparation epithalamin increases the lifespan of fruit flies, mice and rats.
In fruit flies, mice and rats. A cow pineal gland extract helped these animals live longer on average, and lowered their death rate. In one mouse strain, the death rate did not change at all. This is the extract, not the capsule sold as Endoluten.
Epithalamin, the bovine pineal extract, raised mean lifespan by 11 to 31 percent in female Drosophila, SHR mice, C3H/Sn mice and LIO rats. Ninety percent mortality and maximum lifespan rose in flies, C3H/Sn mice and rats. Mortality rate fell 52 percent in flies, 52 percent in rats and 27 percent in C3H/Sn mice, and did not change at all in SHR mice. Note the split: the effect was absent in one of the four mouse and rat groups tested.

Common questions
Has Endoluten been tested in people?
Not in a completed trial cited here. 3 human studies where nobody was given it. Endoluten is a pineal gland capsule sold on the long-life claims of two other products.
What is the Endoluten dosage?
No human dose established. No published study on this page has given this compound to people and reported a result. 3 human studies where nobody was given it
Is Endoluten FDA-approved?
Not approved and not reviewed. Sold as a dietary supplement in the United States. The published data come from pineal gland extracts made as Russian medicines. Those are not approved in the United States, the United Kingdom, Australia or Canada.
Is Endoluten the same as epitalon?
No. Epitalon is one defined lab-made peptide, Ala-Glu-Asp-Gly. Endoluten is a shop capsule, and nobody has published what is in it. They are sold in the same catalogues. They are not the same thing.
Is Endoluten the same as epithalamin?
Not proven. Epithalamin is a cow pineal gland extract, given as shots in the Russian studies. Endoluten is a capsule you swallow. Sellers hint that they are the same. No published test confirms it.
Did epithalamin really cut deaths by 28 percent?
That is what a 12-year study of older heart patients reports. It came from the institute that made the extract. Nobody else has repeated it, and it was never a registered trial. It is a real published number. Weigh who ran the study, and how, before you repeat it.
Will Endoluten help me sleep?
Nobody has tested it. The closest thing is a different product, Pineamin. In 55 older people it raised a melatonin marker 1.9-fold, with no comparison group. That is a chemical change from a different product. It is not better sleep from this one.
Is Endoluten safe?
Nobody knows. None of the study summaries we found in this whole family report side effects. These Russian papers do not usually track safety, so read the silence as missing data.
