Cognitive & Nootropic Research Peptides

Explore neuropeptides and cognitive enhancers studied for their effects on neurotrophic factor expression, neurotransmitter modulation, and neuroprotection. This category includes compounds derived from endogenous brain peptides with documented influence on BDNF, NGF, and dopaminergic signaling pathways.

Semax, derived from ACTH(4-10), has been extensively researched for its ability to upregulate brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF), with studies documenting neuroprotective effects in ischemia models and cognitive enhancement in attention and memory tasks.

Selank, a synthetic analogue of tuftsin, modulates GABA receptor activity and serotonergic neurotransmission, with research characterizing its anxiolytic properties and effects on learning and memory consolidation. Both peptides offer researchers tools to investigate nootropic mechanisms without the tolerance development associated with many small-molecule cognitive enhancers.
