What Is Pinealon?
Pinealon is a synthetic tripeptide made from three amino acids: glutamic acid (Glu), aspartic acid (Asp), and arginine (Arg) — written in shorthand as EDR. It is one of the smallest research peptides studied in neuroscience, with a molecular weight of just 418.40 g/mol. That small size is one of its most important properties — it allows Pinealon to potentially cross the blood-brain barrier and reach neurons directly, which most larger peptides cannot do.
Despite the name “Pinealon” suggesting a pineal gland origin, the peptide was actually isolated from Cortexin — a polypeptide extract from bovine and porcine brain cortex tissue. Khavinson’s team identified EDR as one of the most active short sequences within Cortexin responsible for its neuroprotective properties. They then synthesised it as a standalone tripeptide for research. The name refers to its proposed biological target — the pineal gland and central nervous system — rather than its source.
Pinealon belongs to the Khavinson bioregulator family — the same programme that produced Epithalon (AEDG; pineal/telomere), Thymalin (thymic immune complex), and Vilon (Lys-Glu; immune). Like the other bioregulators, Pinealon’s proposed mechanism is epigenetic: it is thought to bind directly to specific regulatory sequences in DNA, changing which neuroprotective genes are switched on or off. This gene-level mechanism means its effects build up gradually and can persist long after the peptide itself is cleared from the body.
The most studied applications are neuroprotection in Alzheimer’s disease models, oxidative stress reduction in neural tissue, dendritic spine preservation (the structural basis of synaptic connections and memory), and support of serotonin synthesis pathways. Researchers also study Pinealon in models of prenatal hyperhomocysteinemia, traumatic brain injury, and retinal neuroprotection.
How Pinealon Works — Mechanism of Action
Step 1 — Blood-Brain Barrier Penetration
Most peptides cannot reach the brain. They are too large to cross the blood-brain barrier (BBB), and even if they survive gut digestion, the BBB blocks their entry. Pinealon is different. At 418 Da, it is small enough to be transported across the BBB by two peptide transporter systems — PEPT2, which is expressed in the choroid plexus and handles small peptide transport into cerebrospinal fluid, and LAT1, a large neutral amino acid transporter expressed at the BBB that computational studies suggest can bind EDR. Radiolabelled biodistribution studies in rodents (Khavinson group) showed tissue distribution consistent with CNS penetration after systemic injection.
It is important to note the limitation here: while the transporter hypothesis is pharmacologically plausible and the radiolabelled data is suggestive, no independent Western pharmacokinetic study has formally confirmed Pinealon’s brain exposure, distribution volume, or CSF kinetics using modern methods. This is a genuine gap in the current evidence base.
Step 2 — Direct DNA Binding and Epigenetic Gene Regulation
Once inside a neuron, Pinealon is proposed to enter the nucleus and bind directly to specific hexanucleotide sequences in DNA — particularly CCTGCC and CCAGCC motifs. These are the regulatory sequences (promoter regions) that control whether certain genes are transcribed or silenced. Molecular modelling and docking studies published in Pharmaceutics (2021; MDPI) confirmed that EDR binds to B-form double-stranded DNA with lowest-energy contacts at these specific hexanucleotide sequences.
The genes whose promoters contain these EDR-binding sequences include some of the most important in neuroprotection: CASP3 (apoptosis execution), PPARA and PPARG (neuroinflammation regulators), SOD2 and GPX1 (antioxidant enzymes), GAP43 (axonal plasticity), NES (neurogenesis), APOE (Alzheimer’s risk gene), and S100B (synaptic plasticity and neuroprotection). By modulating transcription at these gene promoters, EDR influences multiple neuroprotective pathways simultaneously — not through a single receptor, but through a broad epigenetic programme.
Step 3 — Antioxidant Defence Activation
One of Pinealon’s most documented effects is reduction of reactive oxygen species (ROS) in neural tissue. ROS accumulation damages neurons through lipid peroxidation, protein oxidation, and DNA strand breaks — a key driver of both acute neurological injury and chronic neurodegenerative disease. In prenatal rat models of hyperhomocysteinemia (elevated homocysteine causes oxidative stress in developing brain tissue), Pinealon significantly reduced intracellular ROS accumulation in cerebellum and decreased necrotic cell counts. The mechanism runs through upregulation of SOD2 (superoxide dismutase 2; mitochondrial) and GPX1 (glutathione peroxidase 1) — both confirmed as EDR gene targets by promoter analysis.
Step 4 — Dendritic Spine Preservation and Synaptic Protection
Dendritic spines are the small protrusions on neuron dendrites where synaptic connections form. Losing them means losing memory. In Alzheimer’s disease, dendritic spine loss is one of the earliest and most functionally damaging events — preceding plaque accumulation in many areas and directly causing cognitive decline.
In a 2017 in-vitro study, EDR (Pinealon) and the related peptide KED restored the number of dendritic spines in primary hippocampal neurons exposed to amyloid-beta (Aβ42) oligomers — the toxic species thought to drive synaptic damage in AD. The in-vivo follow-up study (2021; 5xFAD transgenic AD mice; MDPI Pharmaceutics; PMC8227791) confirmed these findings in a living animal model, showing that EDR and KED peptides prevented dendritic spine loss in hippocampal CA1 neurons. EDR also strongly stimulated dendritogenesis — the growth of new dendritic branches — an effect relevant to neuroplasticity research.
Step 5 — Serotonin Pathway Support and Neuroinflammation Modulation
Beyond its antioxidant and structural synaptic effects, Pinealon also acts on the serotonin synthesis pathway. In Alzheimer’s disease cell models, EDR normalised tryptophan hydroxylase expression — the rate-limiting enzyme in serotonin synthesis. Since serotonin deficiency is associated with depression, cognitive decline, and disrupted sleep architecture, this pathway connection links Pinealon to research in mood, circadian biology, and sleep-wake regulation. Separately, Pinealon modulates neuroinflammation through PPARA and PPARG — nuclear receptors that act as master regulators of inflammatory gene programmes in microglia and astrocytes.

Pinealon and Neuroprotection: The Strongest Evidence Domain
The most compelling evidence for Pinealon comes from its effects on dendritic spines in Alzheimer’s disease models. To understand why this matters, you first need to understand what dendritic spines do and why losing them is catastrophic.
Why Dendritic Spines Matter
Dendritic spines are tiny protrusions on the surface of neuron dendrites — there can be thousands on a single neuron. Each spine is the postsynaptic side of an excitatory synapse: the receiving dock where neurotransmitter signals land. When you form a memory, the relevant synapses strengthen — partly by growing more spines, and partly by making existing spines larger and more efficient. When you lose spines, you lose synaptic connections, and with them, the ability to retain and recall information.
In Alzheimer’s disease, dendritic spine loss in the hippocampus is one of the earliest measurable events. It precedes neuron death, it correlates more strongly with cognitive impairment than plaque burden, and it happens before most clinical symptoms appear. Any compound that can protect spines — or stimulate new spine growth — is directly addressing the structural basis of memory loss in AD.
What the 5xFAD Mouse Data Shows
The 2021 study published in MDPI Pharmaceutics (Khavinson et al.; PMC8227791) used the 5xFAD transgenic mouse — the most aggressive genetic Alzheimer’s model available. These mice carry five familial AD mutations that drive rapid amyloid accumulation, synapse loss, and cognitive impairment from the age of two months. It is a demanding test. By four months, they show significant LTP (long-term potentiation) deficits in the hippocampus — the cellular correlate of learning and memory. Dendritic spine counts in hippocampal CA1 neurons are substantially reduced.
Daily intraperitoneal administration of EDR (400 µg/kg) from 2 to 4 months of age prevented this spine loss. The treated mice retained hippocampal CA1 spine density significantly closer to wild-type controls than untreated 5xFAD mice. EDR also stimulated dendritogenesis — the treated neurons showed increased dendritic branching, suggesting not just protection against loss but active promotion of new connections. Molecular docking analysis confirmed that the EDR peptide binds to dsDNA containing hexanucleotide sequences present in the promoter regions of CASP3, GAP43, NES, and APOE — all genes directly relevant to synapse survival, neuroplasticity, neurogenesis, and Alzheimer’s risk.
Honest Assessment of the Evidence
The Pinealon data is genuinely interesting — but it comes almost entirely from Khavinson’s own institute in St. Petersburg, with no independent Western replication. The 5xFAD study is the most rigorous in-vivo data published so far. The human observational TBI data (72 patients) is hypothesis-generating at best — it was not randomised, blinded, or placebo-controlled. There are no Phase 1 or Phase 2 Western clinical trials for Pinealon.
This does not make the research worthless. The mechanistic data — particularly the DNA docking work and the multi-pathway AD cell model findings — is detailed enough to be scientifically productive as a research tool hypothesis. But researchers should treat Pinealon as a mechanistically interesting preclinical compound in need of independent replication, not as a clinically validated neuroprotective agent.

Pinealon Pharmacokinetics
| Parameter | Notes | Research Implication |
|---|---|---|
| Plasma Half-Life | Not formally characterised; tripeptides are rapidly degraded by plasma peptidases; biological effects persist far longer than circulating peptide due to epigenetic gene expression changes | Measure downstream endpoints (gene expression, spine morphology, ROS levels) at hours-to-days, not minutes; plasma Pinealon measurement not standard or necessary |
| BBB Penetration | Proposed via PEPT2 (choroid plexus) and LAT1 (BBB); radiolabelled rodent studies suggest CNS distribution; small MW (418 Da) is conducive to transporter-mediated CNS entry; no independent Western PK confirmation | Design brain endpoint experiments (spine counts, gene expression in brain slices) with this caveat clearly noted; independence of replication needed for this claim |
| Routes of Administration | IP (used in 5xFAD in-vivo study; 400 µg/kg daily); SC; IV; oral (proposed for small tripeptide via PEPT1 intestinal transport — bioavailability low but greater than larger peptides) | IP daily dosing at 400 µg/kg is the validated in-vivo protocol from published 5xFAD data — use this as reference starting point for animal studies |
| In-Vitro Concentration Range | 0.1–100 µg/mL used in cell culture studies; concentration-dependent effects on neural differentiation and spine preservation confirmed | Run a 6-point dose-response (0.01, 0.1, 1, 10, 50, 100 µg/mL) in your cell system before committing to a single concentration; direction of effect on differentiation is concentration-dependent |
| Hygroscopicity Warning | Highly hygroscopic — absorbs atmospheric moisture rapidly; this can affect both measured mass and peptide stability | Weigh Pinealon quickly after removing from −20°C storage; reseal immediately; use desiccant; equilibrate to room temperature inside sealed vial before opening to avoid condensation |
| Metabolism | Proteolytic degradation to Glu, Asp, Arg — all naturally occurring amino acids; no toxic metabolites; no CYP450 involvement expected | No known drug-metabolic interactions; metabolites are non-toxic standard amino acids; this supports the generally benign safety profile observed in animal studies |
Pinealon Side Effects and Safety Profile
| Concern | Evidence | Protocol Note |
|---|---|---|
| No serious adverse events reported | No serious adverse events reported in published animal studies or the 72-patient TBI human observational study; good tolerability profile in all published data | Absence of reported events reflects limited study designs, not confirmed safety; no formal toxicology battery published |
| Injection site reactions | Expected for any injectable; mild and transient; standard IP/SC administration consideration | Rotate injection sites in animal protocols; standard technique applies |
| Hygroscopicity risk | Highly hygroscopic — moisture absorption can cause inaccurate dosing and accelerated degradation | Weigh rapidly, reseal immediately, equilibrate sealed vial to room temp before opening; use desiccant in storage container |
| Concentration-dependent effect direction (neural differentiation) | Stem cell differentiation effects are concentration-dependent; different concentrations can produce different or opposing biological responses | Always run dose-response curves; avoid assuming that more is better in differentiation experiments; validate your specific cell system first |
| Critical data gaps | No Western Phase 1 trial; no formal genotoxicity, carcinogenicity, or repeat-dose toxicology published; no independent PK study; all primary data from one Russian institute | Treat as a preclinical research compound with an interesting mechanism but incomplete characterisation; institutional risk assessment recommended before in-vivo protocols |
| No WADA prohibition | Not listed on WADA 2024–2025 Prohibited List; no performance-enhancing mechanism identified | Verify current WADA list annually before sport science use; WADA list is updated yearly |
Pinealon Quality Control at SourceTides
Every batch of Pinealon Peptide 10 mg from SourceTides passes these tests before release. Pinealon’s hygroscopicity makes moisture control during QC particularly important.
| Test | Method | Specification | Why It Matters |
|---|---|---|---|
| Purity | RP-HPLC (C18; UV 220 nm) | ≥99% peak area purity | As a tripeptide, synthesis impurities are typically dipeptide by-products (Glu-Asp or Asp-Arg); these have different or absent epigenetic activity and confound experiments at >1% contamination |
| Identity | ESI-MS (expected [M+H]⁺ = 419.41 Da) | Confirmed MW 418.40 g/mol; sequence Glu-Asp-Arg confirmed | At 418 Da, EDR is easy to confirm by MS; also confirms the tripeptide sequence vs the dipeptide impurities which appear at different masses |
| Endotoxin | LAL chromogenic assay | <1 EU/mg | Critical for neuronal cell culture experiments — LPS activates NF-κB and inflammatory pathways in neurons and microglia that directly overlap with Pinealon’s PPARA/PPARG anti-inflammatory targets |
| Residual Moisture | Karl Fischer titration | <5% w/w | Especially important for Pinealon given its high hygroscopicity; excess moisture causes dosing inaccuracy and promotes hydrolytic peptide bond degradation |
| Appearance | Visual inspection | White powder; no visible clumping, discolouration, or caking | Clumping is an early sign of moisture absorption; any discolouration indicates oxidation or contamination |
| Cold-Chain Dispatch | Dry-ice packaging; temperature-logged | ≤−20°C throughout transit | Maintains both thermal stability and minimises condensation risk during shipping |
| Certificate of Analysis | Lot-specific PDF | HPLC trace + MS + endotoxin + moisture + dates | Required for research traceability and journal submission |

Frequently Asked Questions
You can buy Pinealon Peptide 10 mg directly from SourceTides. Every order includes a lot-specific Certificate of Analysis with the HPLC chromatogram (≥99% purity), ESI-MS identity confirmation (Glu-Asp-Arg sequence and MW 418.40 Da verified), and the LAL endotoxin result (<1 EU/mg). All vials are lyophilised and dispatched on dry-ice cold chain to protect this hygroscopic compound during shipping.
For primary neuronal culture, dendritic spine morphology assays, and gene expression studies, ≥99% HPLC purity is the recommended minimum. The key impurity concern for Pinealon is incomplete synthesis products — specifically the dipeptides Glu-Asp and Asp-Arg. These appear at different masses (easy to detect by MS) and have different or absent epigenetic activity. At more than 1% contamination, they can confound spine morphology and gene expression results. Mass spectrometry confirmation, included with every SourceTides Pinealon CoA, confirms the correct tripeptide sequence. Endotoxin testing (<1 EU/mg) is equally important — LPS activates NF-κB and PPARA/PPARG pathways that directly overlap with Pinealon’s anti-inflammatory targets.
Hygroscopicity is Pinealon’s most important handling consideration. At 418 Da, it is small and polar enough to absorb atmospheric moisture rapidly. Moisture causes two problems: it makes weighing inaccurate (your measured mass includes water) and it accelerates hydrolytic degradation of the peptide bonds. To handle it correctly: (1) Store the sealed vial at −20°C. (2) Before opening, let the sealed vial equilibrate to room temperature inside the bag — this prevents condensation from forming inside the vial when cold glass meets warm humid air. (3) Open the vial, take what you need, reseal immediately, and return to −20°C. (4) Keep a desiccant (silica gel) in the storage container. (5) Reconstitute in sterile water at 2 mg/mL and use within 7 days (store at 2–8°C) or freeze as single-use aliquots. All SourceTides Pinealon is shipped on dry-ice cold chain with moisture-protective packaging.
Pinealon can be purchased as a research compound in all major Western jurisdictions. In the USA, it is not a DEA scheduled substance and is legally sold as a research chemical. In the UK, it is not a controlled drug under the Misuse of Drugs Act 1971. In Australia, it is an unapproved therapeutic good available for laboratory research. In Canada, it is an unapproved new drug accessible for research use. Pinealon is not on the WADA Prohibited List. SourceTides supplies exclusively for in-vitro laboratory research use only. See the SourceTides shipping policy for jurisdiction-specific dispatch information.
The research base for Pinealon is genuinely interesting but comes with important caveats. The strongest findings are:
Dendritic spine preservation: In vitro (2017) and in vivo 5xFAD mouse (2021) studies showed EDR prevented hippocampal CA1 dendritic spine loss caused by amyloid toxicity and also stimulated new dendrite growth.
Five-pathway AD protection: In AD cell culture models, EDR simultaneously normalised serotonin synthesis, restored antioxidant balance (SOD2/GPX1), suppressed apoptosis (caspase-3, p53), reduced neuroinflammation (PPARA/PPARG), and protected dendritic spines.
Prenatal neuroprotection: Reduced ROS and necrotic cell counts in rat offspring exposed to hyperhomocysteinemia in utero.
TBI human data: 72-patient non-randomised observational study showed cognitive and headache improvements when Pinealon was added to standard TBI therapy.
The key limitation: virtually all primary data comes from Khavinson’s own institute in St. Petersburg. No independent Western replication has been published. All SourceTides Pinealon references are linked on the product page.
This is one of the most important and most debated questions about Pinealon. The short answer is: probably yes, at least partially — but it has not been confirmed by independent Western pharmacokinetic methods.
The evidence for BBB penetration comes from three sources: (1) Khavinson group radiolabelled biodistribution studies in rodents showing tissue distribution consistent with CNS penetration after systemic injection. (2) Computational modelling showing that EDR is a plausible substrate for both PEPT2 (expressed in choroid plexus, important for peptide entry into cerebrospinal fluid) and LAT1 (expressed at the BBB). (3) The biological plausibility argument: at 418 Da, Pinealon is small enough and has the right polarity profile for transporter-mediated BBB crossing — unlike most larger peptides.
The limitation is that no independent Western PK study has formally measured Pinealon’s brain concentration, distribution volume, or CSF kinetics. Until that data exists, BBB penetration should be treated as a well-supported hypothesis rather than a confirmed fact. This should be noted as a caveat in any experimental design that depends on it. All SourceTides Pinealon CoAs document purity and identity to research standards.
Pinealon (EDR) and Epithalon (AEDG) come from the same Khavinson bioregulator programme and share the DNA-binding epigenetic mechanism. They have different targets and research applications.
Epithalon targets the pineal gland and systemic aging via telomerase activation and melatonin restoration. Its 2025 independent Western replication (Al-Dulaimi et al., Biogerontology) makes it the more externally validated of the two. It is used in cellular senescence, telomere biology, and circadian rhythm research.
Pinealon targets the brain cortex specifically — dendritic spine preservation, antioxidant gene expression (SOD2, GPX1), apoptosis suppression (caspase-3), and neuroinflammation control (PPARA, PPARG). It is used in Alzheimer’s disease models, ROS biology in neural tissue, and neuroplasticity research.
In multi-system ageing protocols, researchers often study them together: Epithalon for the cellular and systemic anti-ageing axis, Pinealon for the CNS neuroprotection axis. SourceTides supplies both Pinealon 10 mg and Epithalon 10 mg.
No serious adverse events have been reported in any published Pinealon study — including the 72-patient TBI human observational study and preclinical animal models. The most important safety consideration is not toxicity but experimental design: Pinealon’s effects on neural differentiation are concentration-dependent, and different concentrations can produce different or opposing biological responses in stem cell models. Always run dose-response curves in your specific cell system before committing to a fixed concentration protocol.
From a practical laboratory standpoint, Pinealon’s hygroscopicity is a handling risk — not a toxicity risk. Moisture absorption can cause dosing inaccuracy that undermines your experiment without creating an apparent safety signal. The data gaps are significant: no formal Western toxicology battery, no independent PK study, no Phase 1 trial. Treat it as a preclinical compound with an incompletely characterised safety profile, appropriate for in-vitro research use. All SourceTides Pinealon is supplied for in-vitro laboratory research only.
Equilibrate the sealed vial to room temperature before opening (prevents condensation inside). Dissolve lyophilised Pinealon in sterile water or PBS (pH 7.4) to make a stock solution at 2 mg/mL (approximately 4.78 mM). Swirl gently — do not vortex. Pinealon dissolves easily in water. Filter through a 0.22 µm syringe filter before use in cell culture. For working concentrations, the published range in cell studies is 0.1–100 µg/mL. Important: because neural differentiation effects are concentration-dependent, run a pilot dose-response (0.01, 0.1, 1, 10, 100 µg/mL) in your specific cell line before your main experiment. Store the stock at 2–8°C for up to 7 days, or freeze as single-use aliquots at −20°C. The validated in-vivo IP dose from the 5xFAD mouse study is 400 µg/kg daily. Full reconstitution notes are included in the CoA with every SourceTides Pinealon order.
Pinealon (EDR; Glu-Asp-Arg) and Epithalon (AEDG; Ala-Glu-Asp-Gly) are different peptides from the same Khavinson bioregulator research programme. They share one amino acid overlap (Glu-Asp appears in both sequences) but have different lengths, different complete sequences, and different biological targets. Pinealon is a tripeptide (3 amino acids; MW 418 Da) targeting the CNS. Epithalon is a tetrapeptide (4 amino acids; MW 390 Da) primarily targeting the pineal gland and telomere biology. People sometimes confuse them because both are associated with pineal gland research — but Pinealon was actually isolated from brain cortex extract (Cortexin), not from the pineal gland itself. Both are available from SourceTides.
