Peptide Comparison
PinealonvsSelank
Neuroprotective tripeptide bioregulator (Glu-Asp-Arg) that penetrates the DNA major groove to epigenetically regulate serotonin synthesis, preserve dendritic spine architecture, and activate endogenous antioxidant defenses against age-related neurodegeneration
A clever brain-boosting peptide derived from your immune system's natural tuftsin molecule—it calms anxiety and sharpens your mind without the drowsiness or addiction risks of traditional anti-anxiety medications.

suited for
Pinealon
Neuroprotection against age-related cognitive decline and neurodegeneration
Pinealon is particularly effective for individuals focused on neuroprotection against age-related cognitive decline and neurodegeneration. Research supports its use in this area.
Supporting serotonin production in aging individuals with diminished serotonergic function
Pinealon is particularly effective for individuals focused on supporting serotonin production in aging individuals with diminished serotonergic function. Research supports its use in this area.
Bioregulatory approach to brain aging using Khavinson peptide methodology
Pinealon is particularly effective for individuals focused on bioregulatory approach to brain aging using khavinson peptide methodology. Research supports its use in this area.
Complementing other neuroprotective peptides in comprehensive anti-aging protocols
Pinealon is particularly effective for individuals focused on complementing other neuroprotective peptides in comprehensive anti-aging protocols. Research supports its use in this area.
Selank
Anxiety Without the Fog
If traditional anti-anxiety medications leave you feeling sedated, foggy, or 'not yourself,' Selank offers a refreshing alternative. It calms anxious thoughts while keeping your mind sharp—like turning down the volume on worry without muting your brain.
Cognitive Performers
Students, professionals, and anyone facing demanding mental tasks love Selank for its dual action. It simultaneously reduces performance anxiety while enhancing memory and focus—the best of both worlds when you need to think clearly under pressure.
Stress Resilience Seekers
Chronic stress wreaks havoc on your brain. Selank helps protect against stress-induced cognitive decline by supporting BDNF levels and modulating your stress response. Think of it as building a buffer between you and life's daily pressures.
Natural Approach Enthusiasts
Derived from tuftsin—a natural peptide your own immune system produces—Selank appeals to those seeking more 'natural' solutions. It works with your body's existing systems rather than overriding them like synthetic drugs.

Safety Overview
Pinealon shows excellent safety profile in Russian clinical trials with no serious adverse events at therapeutic intramuscular doses. Well-tolerated with minimal injection site reactions; mild headache reported in <3% of subjects during initiation phase. No systemic toxicity in repeat-dose animal studies; no mutagenicity or carcinogenicity observed. Long half-life reduces dosing frequency; epigenetic changes documented are regulatory (H3K9 acetylation patterns) without genetic mutations.
Contraindications
- xKnown hypersensitivity to Pinealon or its constituent amino acids (glutamic acid, aspartic acid, arginine)
- xPregnancy and breastfeeding — insufficient safety data in reproductive studies
- xConcurrent use of serotonergic medications (SSRIs, MAOIs) without medical supervision — theoretical risk of additive serotonergic effects
- xAutoimmune conditions affecting the CNS — immunomodulatory peptide effects may be unpredictable
Selank
Evidence Level
Limited human trials
FDA Status
Research compound
Safety Overview
Selank has demonstrated a favorable safety profile across multiple Russian clinical studies spanning over two decades. In human trials comparing Selank to traditional anxiolytics like phenazepam, Selank showed comparable anti-anxiety effects with significantly better tolerability and no sedation, dependence, or memory impairment. The peptide has been approved for clinical use in Russia since the 1990s for anxiety and neurasthenia.
Contraindications
- xPregnancy or planning to become pregnant
- xCurrently breastfeeding
- xKnown allergy to peptide components
- xChildren and adolescents
- xSevere psychiatric disorders requiring immediate intervention
