Epitalon vs Endoluten
Written by Aaron CuhaReviewed Sep 2026
The short answer
The lab made four building block peptide, and the capsule sold on its reputation. A PubMed search for Endoluten finds nothing. Every lifespan and death rate number attached to it came from epitalon or from epithalamin, an extract of cow pineal gland. Neither has been shown to be what is in the capsule.

Dose
No human dose established
Amounts that circulate in forums and on vendor pages are not a human dose. Amounts that were given in studies sit in Human evidence on this page.
Commonly reported amounts, in mg, given as short courses. The underlying work is Russian and largely not replicated.
Amounts commonly reported by people buying Epitalon, recorded for this archive's reconstitution calculator, are 5 and 10 mg. They are self-reports rather than trial doses, and this archive does not recommend any of them. No human dose has been established for Epitalon.
| Reported amount | Where the number comes from |

| 10 mg | Commonly reported, no published human dosing trial |

No published study on this page has given this compound to people and reported a result.
3 human studies where nobody was given it
First-hand reports are counted on each profile and never added together. This page sets two published records side by side. It does not pick a winner.
Column A
EpitalonEpitalon (Epithalon, pineal tetrapeptide)
A lab-made peptide based on a pineal gland extract. It has more human data than its reputation suggests, including 266 older people followed for 6 to 8 years and heart patients followed for 12 to 15 years. Almost all of it comes from one research group. None of it used a hidden dummy treatment to compare against.
Column B
EndolutenEndoluten, retail pineal peptide complex capsule
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.
Side by side, on the facts we can check
| What we compare | Epitalon | Endoluten |
|---|---|---|
| Category | Anti-aging | Anti-aging |
| FDA status | Not FDA-approved. On July 24, 2026 the FDA's Pharmacy Compounding Advisory Committee voted 7 to 4, with one member abstaining, in favor of letting pharmacies make it for insomnia. The FDA has not written the rule yet | 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. |
| Half-life | Short (minutes) | 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. |
| Molecular weight | 390.3 Da | Not applicable. This is a peptide complex rather than a single molecule. For comparison, the synthetic tetrapeptide epitalon designed from the parent extract is about 390 Da. |
| How it works | The idea is that Epitalon works as a signal that turns genes on or off, not by fitting a receptor. In people, the most repeated finding is about melatonin, the sleep hormone. A course of the parent pineal extract raised night-time melatonin in older people whose levels were low. It tended to lower it in people whose levels were normal. In human fetal skin cells in a dish that had no telomerase, Epitalon switched on the telomerase gene. The enzyme became active and the telomeres got longer. Untreated cells stopped dividing at round 34. Treated cells kept going to round 44, about ten extra rounds of division. A 2025 study from an unrelated lab found the same direction of effect in normal human cells: longer telomeres, more so at higher doses. Cancer cells in that study used a different route. The step that would link the two ideas is a tiny peptide getting into the cell's nucleus and acting on DNA directly. Only the group that made it has reported that, and it is not settled. | 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. |

Frequently asked questions
What is the difference between Epitalon and Endoluten?
Epitalon: A lab-made peptide based on a pineal gland extract. It has more human data than its reputation suggests, including 266 older people followed for 6 to 8 years and heart patients followed for 12 to 15 years. Almost all of it comes from one research group. None of it used a hidden dummy treatment to compare against. Endoluten: 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.
Which has stronger research evidence, Epitalon or Endoluten?
Each compound gets a band worked out from facts we counted, with the math shown. Epitalon is Moderate (5 completed trials, 266 people given it). Endoluten is Preliminary (3 human studies where nobody was given it). That counts how much has been done in people. It does not rate whether either one works, and neither one is called the winner.
Are Epitalon and Endoluten FDA-approved?
Epitalon: Not FDA-approved. On July 24, 2026 the FDA's Pharmacy Compounding Advisory Committee voted 7 to 4, with one member abstaining, in favor of letting pharmacies make it for insomnia. The FDA has not written the rule yet. Endoluten: 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..
