Peptide Comparison
PinealonvsSemax
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 brain-boosting peptide that supercharges your cognitive function by ramping up BDNF—the protein your neurons need to grow, connect, and stay sharp—all delivered through a simple nasal spray.

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.
Semax
Students and Knowledge Workers
If your day revolves around learning, studying, or processing complex information, Semax can be a game-changer. It enhances memory consolidation and recall while improving your ability to focus for extended periods—perfect for exam prep or demanding projects.
Those Seeking Mental Clarity
Brain fog? Semax works by boosting BDNF—the protein that helps neurons communicate effectively. Users often report feeling like the 'mental static' clears away, leaving sharper, more efficient thinking in its place.
Neuroprotection Seekers
Beyond immediate cognitive benefits, Semax offers protective effects for your brain cells. It acts as an antioxidant (especially against copper toxicity) and supports neuronal health—valuable for anyone concerned about long-term brain wellness.
Recovery Support (Under Medical Supervision)
In Russia, Semax is approved for helping stroke patients and those with traumatic brain injuries recover cognitive function. While not FDA-approved for this use elsewhere, the research shows meaningful neuroprotective and neurorestorative properties.

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
Semax
Evidence Level
Moderate human trials (Phase 1-2)
FDA Status
Research compound
Safety Overview
Semax has been used clinically in Russia for over 25 years with an excellent safety profile. It's approved there for treating stroke, cognitive impairment, and optic nerve diseases. Studies consistently show minimal side effects, mostly limited to mild nasal irritation when using the spray form. Unlike stimulants, Semax doesn't appear to cause tolerance, dependence, or withdrawal symptoms even with extended use.
Contraindications
- xPregnancy or planning to become pregnant
- xCurrently breastfeeding
- xHistory of seizures or epilepsy
- xKnown allergy to ACTH-related peptides
- xUncontrolled hypertension
