A small number of peptides have been studied in the context of cognitive performance, neuroprotection, and stress modulation — primarily in preclinical settings and limited human research. These pages summarize that research for educational purposes only.
Cortexin-10, Cortexin polypeptide complex
A cortex-derived polypeptide bioregulator widely used in Russia and Eastern Europe for cognitive enhancement and neuroprotection. Improves learning, memory, and EEG activity.
DDAVP, dDAVP, Minirin
A synthetic vasopressin analogue with preferential V2R activity. Used medically for diabetes insipidus; studied off-label for memory enhancement and cognitive improvement.
PNB-0408
An extremely potent cognitive enhancer that promotes synaptogenesis and neuroplasticity. Shows remarkable results in Alzheimer's and cognitive decline models.
N-phenylacetyl-L-prolylglycine ethyl ester, Omberacetam
A synthetic dipeptide nootropic with potent cognitive-enhancing and neuroprotective effects. Much more potent than piracetam at lower doses.
CNTF fragment, Peptide 21
A CNTF-derived peptide that stimulates neurogenesis and BDNF production. Shows promise for cognitive enhancement and neurodegenerative disease prevention.
Cortagen, EDR tripeptide
A short synthetic peptide targeting brain tissue with neuroprotective and antioxidant properties. Part of the Khavinson peptide bioregulator family.
TP-7
Selank is a synthetic heptapeptide analogue of tuftsin. Developed in Russia alongside Semax, it is researched for its anxiolytic and nootropic properties without the sedative effects associated with benzodiazepines. It is commonly studied for stress reduction, anxiety management, and cognitive performance in high-demand environments.
ACTH(4-10) analogue, Meksidol
Semax is a heptapeptide analogue of the adrenocorticotropic hormone fragment ACTH(4-10), developed in Russia. It has been approved for use in Russia and Ukraine for cognitive enhancement and neuroprotection. It is researched for nootropic, anxiolytic, and neuroprotective properties in the context of focus, stress resilience, and cognitive performance.
Thyrotropin-Releasing Hormone, Protirelin, Thyroliberin
The hypothalamic tripeptide that regulates thyroid function and has direct CNS effects. Shows antidepressant, neuroprotective, and cognitive-enhancing properties independent of its endocrine role.
ADH, Antidiuretic Hormone, Arginine Vasopressin
A neuropeptide with established effects on memory consolidation, particularly for social and declarative memory. Studied off-label for cognitive enhancement and social memory deficits.
Vasoactive Intestinal Peptide, Vasoactive Intestinal Polypeptide
A 28-amino acid neuropeptide with potent anti-inflammatory and neuroprotective effects. Commonly used in Chronic Inflammatory Response Syndrome (CIRS) protocols.
