Best options to research first

Ranked for this goal by evidence first, then risk. This is a research starting point, not a clinical recommendation.

Semax

ACTH fragment analogue with preclinical neurotrophic signaling and limited clinical stroke/cognition data.

Tier B-Cmed-high riskintermediate

Routes: intranasal. Timeline: Gene expression changes within hours (animal); clinical stroke outcomes are longer-horizon.
