Pinealon
Pinealon (EDR Peptide)
Pinealon (EDR peptide) is a synthetic tripeptide composed of glutamic acid, aspartic acid, and arginine (Glu-Asp-Arg) originally developed by the St. Petersburg Institute of Bioregulation and Gerontology in Russia. It is primarily used as a neuroprotective and nootropic agent, with particular focus on improving cognitive function, supporting sleep quality via pineal gland modulation, and exhibiting cytoprotective effects on brain tissue. Research, largely from Russian institutions, suggests applications in age-related cognitive decline, neuroprotection following hypoxia, and circadian rhythm regulation.
Mechanism of Action
Pinealon is a peptide bioregulator believed to interact with DNA regulatory sequences in pineal and brain cells, influencing gene expression related to neuronal survival, antioxidant defense, and melatonin synthesis pathways. It appears to upregulate expression of proteins involved in neuroprotection, including those limiting apoptosis in neurons under oxidative or hypoxic stress. Additionally, its action on pinealocytes may support endogenous melatonin production, contributing to its effects on circadian rhythm and sleep architecture.

Dosing Protocols
30 minutes before bed
Cycle: 10 days on, 20 days off
Sublingual administration is preferred over oral to bypass first-pass hepatic metabolism and improve bioavailability of the intact tripeptide. Most common protocol in research contexts.
30 minutes before bed on an empty stomach
Cycle: 10-14 days on, 20-30 days off
Higher dose recommended orally due to reduced bioavailability from gastrointestinal proteolysis. Some formulations use enteric-coated capsules to improve delivery.
Evening, approximately 1 hour before sleep
Cycle: 10 days on, 20 days off
Subcutaneous or intramuscular injection provides superior bioavailability. Reconstitute lyophilized powder with bacteriostatic water. Sterile technique is mandatory.
Safety & Side Effects
Pinealon has a generally favorable safety profile based on available Russian preclinical and limited clinical research, with no significant toxicity reported at recommended doses; however, the evidence base is largely from non-peer-reviewed or Russian-language studies with limited independent replication. It is not approved by the FDA or EMA, is sold as a research chemical in most Western countries, and long-term safety data in humans remains insufficient to draw definitive conclusions.
Possible Side Effects
- !Excessive daytime sedation or drowsiness, particularly when dosed in the morning
- !Vivid or unusually intense dreams due to melatonin pathway modulation
- !Mild headache during initial days of use
- !Transient fatigue or low energy during daytime at higher doses
- !Local injection site irritation or redness with subcutaneous administration
- !Potential disruption of circadian rhythm if taken at inconsistent or daytime hours
- !Rare hypersensitivity reactions including mild skin flushing or itching
Interactions
- -May potentiate sedative effects of melatonin supplements, benzodiazepines, and other sleep aids — avoid concurrent use or reduce doses accordingly
- -Potential additive neuroprotective or sedative effects when combined with other peptide bioregulators such as Epithalon or Cerebrolysin
- -May enhance the effects of antioxidant supplements (e.g., NAC, alpha-lipoic acid) through synergistic upregulation of endogenous antioxidant pathways
- -Theoretical interaction with anticoagulants if arginine-mediated NO pathways contribute to mild vasodilation — monitor with blood thinners
- -May modulate cortisol circadian patterns — use caution in individuals on corticosteroid therapy or with HPA axis dysregulation
Cost & Where to Buy
Cost depends significantly on form (oral capsules vs. injectable lyophilized powder), source country, and vendor quality. Russian-manufactured formulations are generally cheapest; Western research peptide vendors charge a premium. A typical 10-day cycle uses minimal product, making monthly costs relatively modest.
