Compounds studied for cognitive and neuropeptide research.
Cognitive and neuropeptide research investigates how synthetic peptides modulate neurotransmission, BDNF and nerve-growth-factor expression, and stress-resilience pathways. The compounds grouped here — the Selank and Semax neuropeptides studied so often together they function as a single research pairing — are investigated in animal and early-stage models for anxiolytic, nootropic, and neuroprotective effects. They are referenced solely as subjects of cognitive research, not as treatments or performance products for human use.
For laboratory research use only. Compounds are catalogued by research interest, not as treatments or outcomes for human use. Last reviewed May 29, 2026.
Each compound below is drawn from our catalog and grouped here by the research interest that defines it. Every card links to its full research and sourcing page; dosing figures are summarized from published research literature, not advice.
anxiolytic neuropeptide
Selank is a synthetic neuropeptide studied in cognitive and anxiolytic research.
nootropic neuropeptide
Semax is a synthetic neuropeptide studied for cognitive research, frequently paired with Selank.

Curated multi-compound protocols built only from compounds we cover, dosed with the published-research literature range, and rated by how mature the research base actually is.
Selank + Semax
The two synthetic neuropeptides are studied together so often they are effectively a single research pairing. Selank is investigated for anxiolytic effects, Semax for nootropic and neurotrophic effects, and research designs combine them for a balanced cognitive profile.
