What Is Pinealon?
Pinealon (Glu-Asp-Arg) is a synthetic tripeptide bioregulator developed by Professor Vladimir Khavinson at the St. Petersburg Institute of Bioregulation and Gerontology. It belongs to the Khavinson bioregulator peptide family — a class of ultra-short synthetic peptides (2–4 amino acids) designed to regulate tissue-specific gene expression. Pinealon is the brain- and pineal gland-specific bioregulator in this family.
Unlike conventional Western peptides that typically work through receptor binding and acute pharmacological effects, Khavinson bioregulators operate on a fundamentally different paradigm. The theory proposes that these short peptides interact directly with DNA regulatory regions in target cells, modulating gene expression in a tissue-specific manner. For Pinealon, the target tissues are neurons and pinealocytes (the melatonin-producing cells of the pineal gland).
Pinealon's proposed mechanisms include regulation of melatonin synthesis in pinealocytes, neuroprotective effects against oxidative stress and excitotoxicity, normalization of circadian rhythms via pineal function restoration, and enhancement of cognitive function. It is often compared to Epitalon — another Khavinson peptide targeting the pineal gland — but the two serve distinct purposes. Epitalon (Ala-Glu-Asp-Gly) primarily activates telomerase for anti-aging via telomere maintenance, while Pinealon (Glu-Asp-Arg) focuses on neuroprotection and melatonin regulation. They are complementary, not redundant.

Key Characteristics:
- Khavinson bioregulator — part of the short peptide bioregulator family developed at the St. Petersburg Institute of Bioregulation and Gerontology
- Tripeptide — 3 amino acids: Glu-Asp-Arg (glutamic acid–aspartic acid–arginine)
- Brain & pineal gland specific — targets neurons and pinealocytes for neuroprotection and melatonin synthesis regulation
- Gene expression modulation — proposed mechanism involves direct peptide-DNA interaction at regulatory regions in target cells, not conventional receptor binding
- Short intensive cycles — 10–20 day cycles repeated every 3–6 months — standard Khavinson bioregulator protocol
- Short plasma half-life — rapid clearance (minutes), but bioregulatory effects on gene expression are theorized to persist well beyond administration

How Pinealon Dosage Is Determined
Pinealon dosing follows the Khavinson bioregulator paradigm, which differs fundamentally from conventional Western peptide pharmacology. Rather than dose-response curves based on receptor saturation kinetics, Khavinson bioregulators use standardized short-cycle protocols established through decades of research at the St. Petersburg Institute. The dosing framework is based on published Russian research, preclinical studies, and clinical observations.
The Khavinson Bioregulator Framework
Khavinson's bioregulation theory proposes that short peptides (2–4 amino acids) can be synthesized to match the regulatory peptides naturally produced during protein metabolism in specific tissues. When administered exogenously, these peptides are theorized to interact with complementary DNA sequences in target cells, restoring optimal gene expression patterns that may decline with aging or disease. The standard protocol uses intensive short cycles (10–20 days) rather than continuous administration, because the gene expression changes are proposed to persist long after peptide clearance.
Preclinical Neuroprotection Studies
Research from Khavinson's group has demonstrated Pinealon's neuroprotective effects in cell culture models. Studies published in the Bulletin of Experimental Biology and Medicine showed that Pinealon protected cortical neurons against oxidative stress-induced apoptosis and reduced markers of excitotoxicity. These studies used concentrations in the nanomolar-to-micromolar range, supporting the low-dose protocol used clinically.
Gene Expression Studies
Published work from the St. Petersburg Institute has demonstrated that Pinealon modulates expression of genes involved in neuroprotection, antioxidant defense, and melatonin synthesis in pinealocyte cultures. Khavinson et al. reported that short peptides, including Pinealon, can penetrate cell membranes and interact with DNA in the nucleus, affecting transcription of target genes. These findings, while published in peer-reviewed journals, await independent replication by Western laboratories.
Clinical Use in Russia
In Russia, Pinealon has been used clinically as a dietary supplement for age-related cognitive decline, sleep disorders, and neuroprotection. The oral capsule form (10 mg, 1–2x daily for 10–30 days) has been available through Russian pharmacies. Clinical observations from Russian practitioners inform the dosing ranges used in the research peptide community, though formal Western clinical trials have not been conducted.
Standard Pinealon Dosage Ranges
Pinealon is available in multiple administration routes: subcutaneous injection (most common in the research peptide community), intranasal, and oral capsules (primarily in Russia). The standard Khavinson protocol uses short, intensive cycles of 10–20 days, repeated every 3–6 months.
Dosage by Administration Route
| Route | Dose | Frequency | Cycle Length | Notes |
|---|---|---|---|---|
| Subcutaneous (standard) | 1–5 mg | 1x daily | 10–20 days | Most common research protocol; best bioavailability |
| Subcutaneous (extended range) | 5–10 mg | 1x daily | 10–20 days | Higher dose used by experienced users; limited additional data |
| Intranasal | 1–5 mg | 1x daily | 10–20 days | May offer more direct CNS access; variable absorption |
| Oral capsule (Russia) | 10 mg | 1–2x daily | 10–30 days | Higher dose compensates for lower oral bioavailability |
Dosage by Experience Level (Subcutaneous)
| Level | Dose | Frequency | Cycle | Notes |
|---|---|---|---|---|
| Beginner | 1–2 mg | 1x daily | 10 days | Assess tolerance; standard starting point for first cycle |
| Intermediate | 3–5 mg | 1x daily | 10–20 days | Standard protocol for most users after initial cycle |
| Advanced | 5–10 mg | 1x daily | 15–20 days | Upper range; limited data above 10 mg supporting additional benefit |
Injection Timing
- Morning or evening: Either timing is acceptable. Some users prefer evening administration due to Pinealon's potential effects on melatonin regulation and sleep quality
- Consistency matters: Choose a consistent time each day throughout the 10–20 day cycle
- Fasting not required: Unlike GH-releasing peptides, Pinealon does not require fasted injection. However, empty stomach may improve absorption
- Once daily is sufficient: The bioregulator paradigm uses single daily dosing — multiple daily injections are not part of the standard protocol

Calculate Your Pinealon Dose
Pinealon is supplied as a lyophilized (freeze-dried) powder, typically in 5 mg or 10 mg vials. You reconstitute it with bacteriostatic water, then draw your dose using an insulin syringe. The concentration depends on how much water you add to the vial.
Worked Example:
- Vial size: 10 mg (10,000 mcg) of Pinealon
- Bacteriostatic water added: 2 mL
- Concentration: 10,000 mcg ÷ 2 mL = 5,000 mcg per mL (5 mg/mL)
- Target dose: 3 mg (3,000 mcg)
- Volume to draw: 3,000 ÷ 5,000 = 0.6 mL = 60 units on an insulin syringe

Pinealon Dosage by Goal
Pinealon's primary applications center on neuroprotection, cognitive support, sleep quality, and brain anti-aging. The optimal protocol varies depending on whether you are targeting sleep and circadian rhythm restoration, cognitive enhancement, neuroprotection, or comprehensive brain anti-aging.
Sleep Quality & Circadian Rhythm Restoration
For users seeking to normalize melatonin production and improve sleep quality through restoration of pineal gland function. This is one of the most common applications, particularly for individuals with age-related melatonin decline or disrupted circadian rhythms. Effects on sleep quality are often the first noticeable benefit, typically within 5–10 days.
- Dose: 1–3 mg SubQ daily
- Timing: Evening administration (2–3 hours before bed)
- Cycle: 10–20 days, repeat every 3–6 months
- Note: Pinealon aims to restore the pineal gland's own melatonin production — it is not exogenous melatonin. Effects may be gradual and persist beyond the cycle
Cognitive Enhancement & Neuroprotection
For users targeting improvements in memory, attention, and neuronal health. This protocol uses the mid-range dose and full cycle duration for maximum neuroprotective benefit. Cognitive effects are typically more subtle than sleep improvements and may develop over weeks to months, including during the rest period.
- Dose: 3–5 mg SubQ daily
- Timing: Morning or evening (consistent timing preferred)
- Cycle: 15–20 days, repeat every 4–6 months
- Stack: Consider adding Semax for complementary nootropic effects through BDNF upregulation
Age-Related Cognitive Decline
For older adults concerned about age-related cognitive decline and brain aging. This is the most studied application in Khavinson's published work. The protocol uses standard dosing with more frequent cycling (every 3–4 months rather than 6) for sustained bioregulatory effects. Combining with Cortagen (brain cortex bioregulator) and Epitalon provides the most comprehensive brain anti-aging approach within the Khavinson framework.
- Dose: 3–5 mg SubQ daily
- Timing: Morning or evening
- Cycle: 10–20 days, repeat every 3–4 months
- Stack: + Epitalon (pineal anti-aging) + Cortagen (brain cortex bioregulation) for comprehensive brain support
Comprehensive Brain Anti-Aging
The most thorough approach within the Khavinson bioregulator paradigm, combining Pinealon with complementary bioregulators for multi-target brain and pineal support. This protocol is used by experienced bioregulator users seeking the full spectrum of proposed neuroprotective and geroprotective effects.
- Dose: 5–10 mg SubQ daily
- Timing: Consistent daily timing throughout cycle
- Cycle: 15–20 days, repeat every 3–6 months
- Full stack: Pinealon + Epitalon + Cortagen (run simultaneously during cycle)
Cycling Protocols
Cycling is the defining feature of Khavinson bioregulator protocols. Unlike conventional peptides that may be used continuously, bioregulators use short, intensive cycles separated by extended rest periods. This is not a desensitization concern (as with GHRPs) but rather the intended protocol design — the theory proposes that gene expression changes initiated during the cycle persist and develop during the rest period.
Standard Cycling Protocols
| Protocol | Cycle Duration | Rest Period | Cycles per Year | Notes |
|---|---|---|---|---|
| Conservative | 10 days | 6 months | 2 | Minimum effective protocol; ideal for first-time users |
| Standard | 10–20 days | 4–6 months | 2–3 | Most common protocol; balances cycle duration with rest |
| Intensive | 20 days | 3–4 months | 3–4 | More frequent cycling for age-related concerns; maximum protocol |
Annual Cycling Strategy
A common approach is to run 2–3 Pinealon cycles per year, spaced evenly. For example: a 20-day cycle in January, a 20-day cycle in May, and a 20-day cycle in September. This provides regular bioregulatory input while maintaining adequate rest periods for the proposed gene expression effects to develop.
Combining Cycles with Other Bioregulators
When stacking Pinealon with other Khavinson bioregulators (such as Epitalon or Cortagen), all bioregulators in the stack are typically run simultaneously during the same cycle window. You do not need to stagger them — they target different aspects of the same tissues and are designed to be used concurrently. This simplifies scheduling and reduces the total number of injection days per year.
Pinealon Stacking Protocols
Pinealon stacking follows the Khavinson bioregulator philosophy of complementary tissue-specific peptides working in concert. The most effective stacks combine Pinealon with other bioregulators targeting the pineal gland (Epitalon) or brain (Cortagen), or with Western nootropic peptides (Semax, Selank) for complementary cognitive and neuroprotective effects.
Pinealon + Epitalon — Comprehensive Pineal Support
The most popular Pinealon stack. Pinealon provides neuroprotection and melatonin synthesis regulation, while Epitalon activates telomerase in pineal tissue for anti-aging. Both target the pineal gland through different mechanisms, making them highly complementary. This is the standard Khavinson pineal gland protocol.
Pinealon + Cortagen (Dual Brain Bioregulator)
Combines two brain-targeting bioregulators for comprehensive central nervous system support. Pinealon targets the pineal gland and neuroprotection, while Cortagen (Ala-Glu-Asp-Pro) is the cerebral cortex bioregulator, targeting higher cognitive functions. Together they provide multi-region brain bioregulation.
| Compound | Dose | Frequency | Purpose |
|---|---|---|---|
| Pinealon | 3–5 mg SubQ | 1x daily for 10–20 days | Pineal gland bioregulation + neuroprotection |
| Cortagen | 1–3 mg SubQ | 1x daily for 10–20 days | Cerebral cortex bioregulation + cognitive function |
Pinealon + Semax (Bioregulator + Nootropic)
Bridges the Khavinson bioregulator and Western nootropic peptide paradigms. Semax is a synthetic heptapeptide analog of ACTH(4-10) that upregulates BDNF (brain-derived neurotrophic factor) and provides acute cognitive enhancement. Paired with Pinealon's longer-term neuroprotective gene expression effects, this stack provides both immediate nootropic benefit and sustained bioregulatory support.
Pinealon + Selank (Neuroprotection + Anxiolysis)
For users seeking neuroprotection combined with anxiety reduction and stress resilience. Selank is a synthetic heptapeptide with anxiolytic and nootropic properties, modulating GABA, serotonin, and dopamine systems. Combined with Pinealon's melatonin regulation and neuroprotective effects, this stack supports both daytime cognitive resilience and nighttime sleep quality.
Full Khavinson Brain Protocol (Pinealon + Epitalon + Cortagen)
The comprehensive brain and pineal anti-aging stack using three complementary Khavinson bioregulators. This protocol targets pineal melatonin function (Pinealon), telomere maintenance (Epitalon), and cerebral cortex bioregulation (Cortagen) simultaneously. Used by experienced bioregulator users for maximum neuroprotective coverage.

Safety, Side Effects & Contraindications
Reported Side Effects
Rare and generally mild:
- Drowsiness — the most commonly reported effect, likely related to melatonin modulation. Usually mild and may actually be beneficial for users targeting sleep improvement
- Injection site reactions — mild redness, minor soreness at the injection site. Typical of subcutaneous peptide injection and generally resolves quickly
- Headache — rare, usually mild and transient. More commonly reported in the first few days of a cycle
- Vivid dreams — some users report more vivid or memorable dreams during Pinealon cycles, potentially related to melatonin and sleep architecture effects
Not reported in published literature:
- Hormonal disruption (cortisol, prolactin, testosterone, estrogen)
- Organ toxicity
- Dependency or withdrawal effects
- Significant GI disturbance (with SubQ administration)
Contraindications
- Active cancer or history of cancer — any compound that modulates gene expression should be avoided in the presence of active malignancy. While Pinealon has not been shown to promote tumor growth, the theoretical concern is sufficient to warrant avoidance.
- Pregnancy and breastfeeding — no safety data exists for Pinealon during pregnancy or nursing. Any peptide that modulates gene expression should be avoided during these periods as a precautionary measure.
- Autoimmune neurological conditions — conditions such as multiple sclerosis or autoimmune encephalitis represent situations where immune-modulated CNS activity could theoretically be affected by bioregulator peptides. Use only under medical supervision.
- Known allergy to component amino acids — while extremely rare, hypersensitivity to any of the three amino acids (glutamic acid, aspartic acid, arginine) is a contraindication.
- Concurrent melatonin supplementation at high doses — if Pinealon increases endogenous melatonin production as theorized, combining with high-dose exogenous melatonin could lead to excessive melatonin levels. Coordinate with a healthcare provider if using both.
When to Stop or Reduce Dose
- Excessive drowsiness that impairs daytime function — reduce dose or switch to evening-only administration
- Persistent headache beyond the first 3–4 days of the cycle
- Any allergic reaction (rash, swelling, difficulty breathing) — discontinue immediately and seek medical attention
- Any symptom that feels unusual or concerning — err on the side of caution and discontinue
