PUBMEDLow

Mechanistic literature suggests Semax may influence hippocampal BDNF/trkB-related signaling; this is supportive biology rather than definitive clinical efficacy.

Overall brain health evidence appraisal
Humans (evidence review)Independent evidence review
PUBMEDLow

An independent cognitive vitality report reviews Semax & emphasizes limited high-quality human clinical evidence for cognitive outcomes.

Dose:
Neurotrophin signaling & gene expression after cerebral ischemia (mechanistic)
Rats (ischemia/reperfusion model)Mechanistic/animal
PUBMEDLow

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.
