Deep Dive Highlights
Semax
Attention, learning, and stress resilience angles in research contexts.
Selank
Anxiolysis without sedation is the key narrative; workplace social and presentation benefits.
P21
CNTF‑derived concept peptide; early evidence and high‑caution profile.
Cerebrolysin
Clinical‑context peptide mixture explored for neuroprotection and recovery.
Dihexa
Preclinical synaptogenic discussions; human data remain limited.
Mechanisms & Pathways
Brain health depends on neuroplasticity, neuroinflammation control, vascular integrity, and metabolic support. Semax/Selank literature discusses neurotrophic and anxiolytic angles; P21/Dihexa target neurotrophic/synaptogenic hypotheses; Cerebrolysin has clinical‑context use. Lifestyle levers — sleep depth, resistance training, cardiorespiratory fitness, and cognitively demanding work — remain primary drivers.
Evidence Landscape
Human evidence varies widely across entries. We emphasize transparent uncertainty: where studies are small, open‑label, or preclinical, interpret cautiously. Build your plan around validated brain health practices first, then explore research literature with a critical eye.
Long‑Horizon Plan
Weekly anchors: 3x resistance training, 150+ minutes zone 2 cardio, skill learning (language or instrument).
Daily basics: 7–9 hours sleep, Mediterranean‑leaning diet pattern, social connection, focused work blocks.
