Semax
ACTH fragment analog researched in neuroprotection/nootropic contexts; most evidence is mechanistic/preclinical or limited clinical literature.

Mechanistic literature suggests Semax may influence hippocampal BDNF/trkB-related signaling; this is supportive biology rather than definitive clinical efficacy.
An independent cognitive vitality report reviews Semax & emphasizes limited high-quality human clinical evidence for cognitive outcomes.
Animal work demonstrates that Semax activates transcription of neurotrophins (BDNF, TrkC, TrkA) & suppresses pro-inflammatory gene expression after cerebral ischemia; this is not direct proof of cognitive improvement in healthy humans.
