Pinealon vs Semax

Research material comparison: purity standards, available formats, molecular data, batch COA documentation, and regulatory status. For in vitro research use only.

Pinealon: DSemax: D
AttributePinealonSemax
CategoryNootropic / NeuroprotectiveNootropic / Neuroprotective
Evidence RatingD — Preclinical / Uncontrolled Russian StudiesD — Preclinical
Clinical StatusPreclinical / small open-label Russian studies only. No controlled clinical trials. Sold as a dietary supplement in Russia.Approved in Russia and Ukraine for stroke and cognitive disorders; not approved elsewhere
MechanismAccording to the Khavinson bioregulatory peptide theory, pinealon is proposed to penetrate cell membranes, enter the nucleus, and interact with specific DNA sequences to regulate gene expression related to neuronal function and pineal melatonin synthesis. Preclinical studies from the Khavinson group...Semax is a brain-selective heptapeptide (Met-Glu-His-Phe-Pro-Gly-Pro, MW ~813.88 g/mol) that crosses the blood-brain barrier via intranasal absorption. It increases brain-derived neurotrophic factor (BDNF) expression and upregulates trkB receptors, supporting neuroplasticity and long-term memory for...
Half-Life—~3–5 minutes; intranasal extends effective duration

Molecular Weight~418 g/mol~813.9 g/mol
WADA StatusNot ListedNot Listed
Research Half-Life—~3–5 minutes; intranasal extends effective duration
Key Use Cases
  • Neuroprotection Research
  • Anti-Aging Research
  • Cognitive Enhancement
Safety Concerns
  • No controlled safety studies have been conducted
  • No serious adverse effects reported in Russian open-label observations
  • Long-term safety is unknown
  • Generally favorable safety profile with uncommon mild side effects and no dependence potential
  • No significant hormonal effects despite ACTH-fragment origin — brain-selective mechanism reduces systemic side effects
  • Administered intranasally — mild nasal irritation possible; proper spray technique recommended
Contraindications
  • Pregnancy and breastfeeding (no safety data)
  • No established contraindications due to absence of clinical data
  • Not recommended for use in place of evidence-based treatments for neurological conditions
  • Pregnancy and breastfeeding (insufficient data)
  • Acute psychosis (theoretical concern regarding dopaminergic enhancement)
  • Individuals with mood disorders should use caution (dopamine effects may interact with mood conditions in complex ways)
  • Combining with other dopamine-active substances warrants caution
Regulatory (US)Not FDA-approved or evaluated. Not available as a pharmaceutical. Occasionally sold online as a research peptide.Not FDA-approved. Removed from FDA Category 2 on April 15, 2026. PCAC review scheduled July 23-24, 2026. Previously classified as Category 2, prohibiting compounding. Research chemical.
