Best Peptides for Cognitive Performance
Peptides that enhance focus, memory, neuroprotection, and overall brain function.
Top Peptides for Cognitive Performance
| Peptide | Evidence | Use Case | Actions |
|---|---|---|---|
| SemaxTop Choice Semax is a synthetic peptide derived from ACTH (adrenocorticotropic hormone). Developed in Russia as a nootropic and neuroprotective agent. | high | Well-studied nootropic with BDNF enhancement | |
| DihexaTop Choice Dihexa is a nootropic peptide derived from angiotensin IV. It has shown remarkable cognitive-enhancing properties in animal studies, being described as potentially millions of times more potent than BDNF. | medium | Extremely potent cognitive enhancer in animal models | |
| PinealonTop Choice Pinealon is a short synthetic peptide developed from research on the pineal gland. It has shown neuroprotective and cognitive-enhancing properties in animal studies. | low | Limited but promising research on neuroprotection | |

Also known as NASA, it provides stronger and longer-lasting nootropic effects than standard Semax. | medium | Enhanced Semax with improved stability and potency | |
| NoopeptTop Choice Noopept (N-phenylacetyl-L-prolylglycine ethyl ester) is a peptide-derived nootropic developed in Russia. While technically a dipeptide prodrug rather than a true peptide, it's often discussed alongside peptide nootropics. | medium | Well-studied peptide-derived nootropic with NGF/BDNF effects | |
| P21Top Choice P21 is a synthetic peptide derived from Cerebrolysin, specifically designed to mimic the neurotrophic effects of the parent compound. It promotes neurogenesis and has shown cognitive-enhancing properties in research. | medium | Promotes neurogenesis through GSK-3β inhibition | |
| SelankTop Choice Selank is a synthetic peptide derived from the naturally occurring immunomodulatory peptide tuftsin. Developed in Russia for anxiety and cognitive enhancement. | high | Primary nootropic and anxiolytic effects | |
| CortexinTop Choice Cortexin is a polypeptide complex derived from pig brain cortex, used clinically in Russia and Eastern Europe for neurological conditions including stroke recovery, traumatic brain injury, and cognitive decline. | medium | Used clinically for cognitive support in Eastern Europe | |
| FGLTop Choice FGL (FG Loop) is a synthetic peptide that mimics the neural cell adhesion molecule (NCAM) FG loop region. It promotes neuroplasticity and has shown cognitive-enhancing effects in research. | medium | NCAM mimetic with neuroplasticity-promoting effects in research | |
| PE-22-28Top Choice PE-22-28 is a synthetic peptide fragment derived from research on the SAMP8 mouse model of accelerated aging. It has shown potential for enhancing memory and reducing cognitive decline. | low | Experimental peptide from aging research | |
| Semax & SelankTop Choice A nootropic combination pairing two Russian-developed peptides for cognitive enhancement. Semax provides stimulating focus and neuroprotection while Selank offers anxiolytic and mood-stabilizing effects, creating a balanced cognitive enhancement stack. | high | Primary use - balanced nootropic effects | |
| AdamaxTop Choice Adamax is a modified version of Semax with an adamantane group attached, designed to enhance its nootropic effects and extend duration of action compared to standard Semax. | low | Enhanced Semax variant with potentially stronger effects | |
| CerebrolysinTop Choice Cerebrolysin is a mixture of low-molecular-weight neuropeptides and free amino acids derived from purified pig brain proteins. It is approved in many countries for stroke, traumatic brain injury, and dementia. | high | Extensive clinical research for neurological conditions | |
| NA-Selank AmidateTop Choice NA-Selank Amidate (N-Acetyl Selank Amidate) is an enhanced version of Selank with improved stability and blood-brain barrier penetration. The modifications increase bioavailability and duration of cognitive and anxiolytic effects. | medium | Enhanced version of Selank with better bioavailability | |
| Oxytocin Oxytocin is a natural hormone produced in the hypothalamus, often called the 'love hormone' or 'bonding hormone.' It plays key roles in social bonding, childbirth, lactation, and stress regulation. | medium | Improves social cognition and reduces social anxiety | |
| Humanin Humanin is a mitochondrial-derived peptide with potent cytoprotective effects. Discovered in 2001, it has shown promise in protecting against age-related diseases including Alzheimer's, cardiovascular disease, and diabetes. | medium | Shows neuroprotective effects in Alzheimer's models | |
| Substance P Substance P is an 11-amino acid neuropeptide involved in pain transmission, inflammation, and various neurological processes. While not used therapeutically itself, understanding it is crucial for pain research. | low | Important neuropeptide in pain and mood research - antagonists have therapeutic potential |
