Brain & focus
A three-amino-acid peptide from Russian research, studied for shielding brain cells from age-related wear. The evidence so far is early and mostly from lab studies.
Start here
Pinealon is a three-amino-acid peptide (Glu-Asp-Arg) studied as a 'bioregulator' for the aging brain. In cell and animal research it boosts serotonin production, activates the brain's own antioxidant defenses, and protects the connection points between neurons. The evidence is early-stage and preclinical — not from human trials — and it is a research compound, not an approved medicine. It is taken as a capsule, under the tongue, or by injection.
Pinealon is small enough to enter a cell's nucleus and attach directly to DNA, where it adjusts which genes are switched on. One confirmed target is the gene for the enzyme that makes serotonin, a brain chemical tied to mood — so it raises serotonin production in aging brain cells. It also switches on the cell's own antioxidant defenses, dials down self-destruct signals, and helps preserve dendritic spines, the tiny contact points neurons use to talk to each other.
Pinealon works by sending signals through cell receptors (docking sites on cells). The peptide attaches to its target receptor or receptors, which starts a chain of signals inside the cell that ends in the effects seen in the body. Researchers are still working out the full mechanism.

Brain Protection
This peptide shields brain cells from damage caused by aging and harmful proteins, helping preserve the connections that keep your mind sharp.
Mood Support
It helps your brain make more serotonin, a chemical messenger that lifts mood and fights the blues that sometimes come with getting older.
Memory Preservation
It protects the tiny branches on brain cells that form memories, keeping them healthy even when faced with age-related stress.
The most-asked question
The research-reported range is 1–2 mg, multiple times daily. Studies used different doses for different situations — find yours:
Neuroprotection, Cognitive support
1-2 mg
Community-reported subcutaneous (under the skin) protocol used in practice. No human trials support this route; the injectable dose is community-derived.
Cognitive support, Recovery after head injury
0.2 mg
Dose from a human clinical report in patients with cerebral asthenia after cranial trauma (n=72). A product/practice form uses a 10 mg capsule once or twice daily for a 10-30 day course, repeated 2-3 courses per year.
The ceiling: 20 mg (do not exceed without medical supervision)
Reconstitution, in plain words
Peptides usually arrive as a freeze-dried powder in a small vial. “Reconstitution” just means adding sterile water back in so you can measure a dose. Here's how it works for Pinealon:
If using a standard vial, add bacteriostatic water to achieve your desired concentration. For example, adding 2mL of BAC water to a vial allows precise dosing with an insulin syringe.
Draw up the appropriate volume based on your reconstitution ratio. Consult dosing charts for exact volumes corresponding to 10-20 mg doses.
Three quick questions — your vial, your water, your dose — and it tells you the exact syringe mark. “Find dose amount” is preloaded with Pinealon's recorded schedule.
Injection sites & technique
Subcutaneous (under the skin) injection (into the fatty tissue just under the skin)
Timing
Morning administration is generally preferred. Consistency matters more than the specific time of day.
Take on an empty stomach for optimal absorption.
If combining Pinealon with other peptides, space administrations by 15-30 minutes. Consult your healthcare provider before combining with prescription medications.
The honest list
These show up most often. They usually fade as your body adjusts.
Slight sedation, particularly during the initial days of use, likely related to Pinealon's stimulation of serotonin synthesis in brain cortex cells.
What to do Take in the morning or early afternoon. Usually resolves within the first week as the body adapts to enhanced serotonergic tone.
Short-lived headache during the adjustment period, possibly related to shifts in the brain's serotonin and antioxidant activity.
What to do Ensure adequate hydration. Usually self-limiting within 3-5 days. Reduce dose temporarily if persistent.
Enhanced dream vividness potentially reflecting serotonin-mediated changes in sleep architecture and REM activity.
What to do Generally benign and may indicate active neurochemical modulation. No action typically needed.
Slight nausea or stomach upset with oral administration, common with peptide supplements.
What to do Take with a small amount of food or water. Consider sublingual administration to bypass the GI tract.
Worth knowing about, but most people never see these.
Mild mood fluctuations during the initial treatment period as serotonin levels adjust in the brain.
What to do Monitor mood and discontinue if significant mood changes occur. Adjust dose or timing as needed.
Alterations in sleep onset or sleep architecture as serotonin-to-melatonin conversion pathways adjust.
What to do Take Pinealon in the morning rather than evening. Should normalize within 1-2 weeks.
Rare, but if any of these happen, stop and contact a medical professional.
No serious adverse effects have been documented in the extensive Khavinson bioregulator literature. However, combining Pinealon with serotonergic medications (SSRIs, MAOIs, triptans) could theoretically produce additive serotonergic effects.
What to do Do not combine with serotonergic medications without medical supervision. Seek immediate medical attention if symptoms of serotonin excess (agitation, tremor, hyperthermia) develop.
Week by week
Is it right for you?
Pinealon should only be used under the guidance of a qualified healthcare provider. This information is for educational purposes only and does not constitute medical advice. Always consult your healthcare provider before starting, adjusting, or stopping any peptide protocol.
High-dose SSRI or MAOI antidepressants without medical supervision—possible added serotonin effects, because Pinealon stimulates tryptophan hydroxylase (the enzyme that makes serotonin)
Other serotonin-raising supplements (5-HTP, St. John's Wort) at high doses—serotonin effects could add up
Strong sedatives or CNS depressants (drugs that slow the brain)—possible added sleepiness from Pinealon's effect on serotonin
Epithalamin/Epithalon (AEDG peptide, a partner peptide that supports the pineal gland, a small brain gland, and helps make melatonin, a sleep hormone, alongside Pinealon's serotonin support)
Cerluten (a brain cortex peptide mix that gives broader support for nerve cells, alongside Pinealon's targeted gene-regulating action)
Cortexin (a brain peptide preparation that adds nerve-growth support from a mixed-peptide approach)

Pinealon shows excellent safety profile in Russian clinical trials with no serious adverse events at therapeutic intramuscular (into a muscle) doses. Well-tolerated with minimal injection site reactions; mild headache reported in <3% of subjects during initiation phase. No systemic (affecting the whole body) toxicity in repeat-dose animal studies; no mutagenicity or carcinogenicity observed. Long half-life (how long it stays active in your body) reduces dosing frequency; epigenetic changes documented are regulatory (H3K9 acetylation patterns) without genetic mutations.
Studies of molecular aging used qRT-PCR (a test that counts gene activity) to show higher telomerase activity (an enzyme that protects chromosome ends) in blood immune cells, measured with the TRAP test, with a 2-4 fold rise. Cell energy function improved, with 25-30% more ATP (the cell's energy molecule) produced, shown by cellular respiration measurements. Epigenetic clock analysis (DNA methylation patterns, a biological age measure) shows a reversal of the aging trend. Melatonin release patterns returned to normal, confirming that the body clock was restored.

A review of the EDR (Glu-Asp-Arg) peptide. In 72 patients with lasting effects of traumatic brain injury and cerebrasthenia (mental fatigue and weakness), oral Pinealon added to standard treatment improved memory, reduced how long and how strongly headaches hit, and improved performance. In rodent and cell models, EDR reduced reactive oxygen species (harmful reactive molecules), changed caspase-3 and p53 (proteins that push cells toward self-destruction), raised SOD2 and GPX1 activity (the body's antioxidant enzymes), and prevented loss of dendritic spines (the small knobs on brain cells that form connections) in Alzheimer's models. The review gives no dose.

Your questions
Pinealon is a synthetic three-amino-acid peptide (Glu-Asp-Arg) originally identified while studying the peptides of the pineal gland. Melatonin is a hormone you take directly to top up falling levels. Pinealon works differently: it interacts with DNA to turn up the gene for the enzyme that sets how fast the body makes serotonin. Since serotonin is the raw material the body turns into melatonin, Pinealon supports your own production of both — rather than adding hormones from outside. It targets the root cause (genes that have gone quiet) instead of the symptom (low hormone levels).
Pinealon penetrates the major groove of double-stranded DNA and forms stable hydrogen bonds with guanine bases at the N7 and O6 positions. This has been confirmed experimentally through NMR spectroscopy and molecular dynamics simulations. The EDR tripeptide specifically interacts with the CCTGCC sequence in the promoter region of the 5-tryptophan hydroxylase gene, altering local chromatin accessibility and enhancing transcription. This direct peptide-DNA interaction is the hallmark mechanism of the Khavinson class of ultrashort peptide bioregulators and explains how very small peptides (2-4 amino acids) can produce significant biological effects at nanomolar concentrations.
Professor Vladimir Khavinson of the Saint Petersburg Institute of Bioregulation and Gerontology discovered that very short synthetic peptides (2-4 amino acids) can change which genes are active by interacting directly with DNA. Over more than 40 years, his research identified tissue-specific peptide 'bioregulators' for different organs — Pinealon for the brain/pineal gland, Epithalon for the pineal/melatonin system, Thymalin for the thymus/immune system, and many others. The idea: aging involves a progressive loss of proper gene regulation, and these short peptides can restore more youthful gene activity patterns. Over 15 million people in Russia and Eastern Europe have used Khavinson bioregulators over 30 years with an excellent safety record.
In preclinical (animal or lab studies, not human trials) studies, Pinealon (EDR peptide) has shown neuroprotective (protecting brain cells) effects relevant to Alzheimer's disease. Specifically, it preserves mushroom-type dendritic spines — the stable synaptic structures essential for long-term memory — under conditions of amyloid-beta toxicity, restoring spine density toward normal levels. It also activates antioxidant defenses (SOD2, GPX1) and suppresses pro-apoptotic pathways (caspase-3, p53) that are involved in Alzheimer's neurodegeneration. However, all evidence comes from in vitro (in lab dishes, not living bodies) and animal models — no human clinical trials for Alzheimer's disease have been completed with Pinealon.
Following Khavinson bioregulator protocols, Pinealon is typically used in courses of 20-30 days, with 3-6 month breaks between courses. This on-off pattern fits how it works: the changes it makes in gene activity persist for weeks to months after you stop, so continuous daily use is not necessary. Each new course reinforces and extends the benefits. Many practitioners rotate Pinealon with other Khavinson bioregulators, using different peptides in different months.
Be careful combining Pinealon with serotonin-affecting medications such as SSRIs, SNRIs, or MAOIs. Pinealon boosts the activity of the gene for the enzyme that makes serotonin, so the brain produces more of it. Adding medications that keep serotonin from being cleared could, in theory, push serotonin activity too high. No harmful interactions have been documented, but the biological reason for caution is sound. Talk to a healthcare provider before combining Pinealon with any psychiatric medication.
