Cognitive Domains
5 functional clusters with direct entry access
4 compounds – AMPA / mGluR modulation
Racetams
Racetams modulate AMPA-glutamate and metabotropic glutamate receptors, enhancing cholinergic transmission and long-term potentiation (LTP).
4 compounds – eugeroic stimulants
Modafinil-types
Eugeroic (wakefulness-promoting) agents acting via the dopamine transporter and histamine H3 receptor system. Clinically indicated for narcolepsy and shift-work sleep disorder.
4 compounds – D2/D3 + MAO modulators
Dopamine / Motivation
Modulators of the dopaminergic motivation system: selective MAO-B inhibitor (Selegiline), D2-positive allosteric modulator (9-Me-BC), adaptogen (Bromantane), and caffeine metabolite (Paraxanthine).
5 compounds – BDNF inducers and synaptogenic agents
BDNF / Neuroplasticity
BDNF (Brain-Derived Neurotrophic Factor) and synaptogenesis enhancers: Dihexa (Ang-IV analog), NSI-189 (neurogenic), J-147 (mitochondrial), Semax (Russian ACTH analog) and Adamax (Semax-adamantyl conjugate).
4 compounds – acetylcholine substrate + receptor modulation
Cholinergic Boosters
Acetylcholine precursors (CDP-Choline, Alpha-GPC) elevate synaptic ACh levels. Pramiracetam and AF710B are muscarinic-receptor selective modulators.

MolekulaX is an educational platform that presents the mechanisms of action, pharmacokinetics and research background of peptides, nootropics, performance enhancers and pharmaceuticals on a scientific basis. Content is sourced exclusively from peer-reviewed literature, PubMed, FDA prescribing information, EU EMA SmPC and NIH PubChem. Influencer-style curated notes and RUO-aggregator sites are not part of our source list.

A peptide is a short amino-acid chain (usually 2-50 amino acids) that is almost always injected because oral administration leads to digestion. A nootropic is a broader category: cognition-enhancing substances that can be small molecules (racetams, eugeroics), amino acids (L-Theanine), plant extracts (Bacopa, Rhodiola) or peptides themselves (Semax, Selank, Cerebrolysin). The overlap sits in the peptide-nootropic category.
