Pinealon is a synthetic 3-amino-acid peptide (glutamic acid, aspartic acid, arginine, often written EDR) from the St. Petersburg Institute of Bioregulation and Gerontology in Russia, the same group behind epitalon.[1][3] In lab and rat studies it protected brain cells from oxidative stress and low oxygen.[1][7] But nearly all research comes from Russian groups tied to its developers, and the few human studies are small and thinly described.[10][14] It is not approved as a medicine anywhere we could confirm.
What is pinealon?
Pinealon belongs to a family of very short “peptide bioregulators” developed by Vladimir Khavinson’s group. The group’s theory is that these tiny peptides enter cells, bind to DNA or histone proteins and switch particular genes on or off.[3] That idea rests mainly on computer docking models and cell studies, not on direct evidence in people.[3][5]
Despite the name, pinealon is studied mostly as a brain peptide, not a pineal one. In a Russian study of rat pineal tissue, epitalon raised markers of pineal cell growth and secretion, while pinealon did not.[13]
Pinealon benefits: what the research shows
Cell and animal studies
- Oxidative stress: in rat brain cells, immune cells and a nerve-like cell line, pinealon cut levels of harmful reactive oxygen species and reduced cell death.[1]
- Low oxygen: among four Khavinson peptides tested in an animal model of low air pressure, pinealon had the strongest effect against low-oxygen stress.[7]
- Learning in rats: in a Russian rat study, pinealon improved maze learning in young and old animals more than the brain-extract drug Cortexin.[8] In old rats exposed to low oxygen, a separate study suggested it brought inflammation markers back toward normal.[9]
- Blocked neck arteries: in old rats whose carotid arteries were tied off, pretreatment with pinealon or Cortexin improved survival, although pinealon also reduced exploration and movement and moderately raised caspase-3, an enzyme involved in cell death.[19]
- Prenatal stress: rats born to mothers with high homocysteine learned better if their mothers had received pinealon.[2]
- Alzheimer’s models: in mouse nerve cells exposed to amyloid, the toxic protein linked to Alzheimer’s disease, pinealon restored the number of mature dendritic spines (the contact points between neurons).[4] A follow-up in Alzheimer’s-model mice reported similar protection of spines.[5]
- Serotonin: in aging brain-cell cultures, pinealon raised serotonin expression.[6]
Human studies
| Study | People | What was reported |
|---|---|---|
| Adults with organic brain syndrome (Russia, 2015) | 32 adults aged 41 to 83 | Slower “biological age” markers with pinealon and a related peptide, vesugen; vesugen did better[10] |
| Truck drivers (Russia, 2012) | 150 truck drivers (150 metal workers served as a survey comparison group) | Better stress and mood scores with peptide bioregulators, best when pinealon and vesugen were combined[11] |
| Comparison of anti-aging methods (Russia, 2016) | 110 people | Pinealon plus vesugen had the largest effect on biological-age markers[12] |
Why the pinealon evidence is hard to judge
- One research network. Nearly every study comes from Khavinson’s institute or Russian groups working with it, often in a Russian-language journal. We found no independent replication outside Russia.[14]
- Mechanism by modeling. The claim that pinealon switches genes on and off rests largely on computer docking, which shows where a peptide could bind DNA, not that it does so in a living brain.[5] Even how such short peptides would get into cells has been studied mainly by computer modeling.[20]
- Mixed lab signals. Pinealon is marketed as an antioxidant, yet one Russian lab study found that short peptides including pinealon had no direct antioxidant activity and raised steady-state levels of reactive oxygen species inside nerve cells, even as fewer cells died.[21]
- Thin human reports. The human studies measure “biological age” scores and questionnaires, not memory tests, sleep or disease outcomes.[10][12]
Pinealon vs epitalon
| Pinealon | Epitalon | |
|---|---|---|
| Structure | 3 amino acids: Glu-Asp-Arg[1] | 4 amino acids: Ala-Glu-Asp-Gly[13] |
| Main research focus | Brain cells, oxygen stress, learning in rats[1][8] | Telomeres, pineal gland, lifespan in animals (see our epitalon profile) |
| Effect on rat pineal tissue | No effect on growth or secretion markers[13] | Raised growth and secretion markers[13] |
| US regulatory picture | Not on any FDA compounding list[15] | Reviewed by FDA advisers in 2026 |
Both peptides come from the same institute and share the same evidence problem: almost all research comes from one network of Russian scientists. For other Russian brain peptides with more clinical history, see Semax and Selank.
Pinealon dosage
There is no approved or established dose. The Russian human studies do not report doses in their abstracts, and no human pharmacokinetic data (how the body absorbs and clears it) have been published that we could find.[10][12] Doses discussed online come from vendors and forum users, not trials. If you are trying to understand vial math in general, our peptide calculator explains how concentration and syringe units relate, but it cannot make an untested dose safe.
Pinealon side effects
- Largely unknown in people. No long-term safety, cancer or reproductive studies have been published.
- Blood and oxidation signals: one Russian study of 32 adults reported pro-oxidant activity and a drop in CD34+ blood stem cells with pinealon and vesugen; the authors still described them as safe at the genetic (chromatin) level and said this needs further study.[10]
- Product quality: pinealon sold online is a research chemical, so purity, dose and sterility are not checked by any regulator.
Is pinealon legal?
- US: not FDA-approved. Pinealon does not appear on any of FDA’s 503A bulk substance lists (under evaluation, safety concerns or inadequate support) as of May 14, 2026, which suggests no one has nominated it for compounding.[15] It is also absent from FDA’s list of substances with significant safety risks.[16] In our reading, that leaves no legal route for pharmacies to compound it.
- Sports: pinealon is not named on WADA’s 2026 list, but as a substance with no government approval for human use, in our reading it falls under the S0 category, which is banned at all times.[17]
