Quick Answers
Which is better, Selank or Semax?
Neither compound has a universal evidence advantage. Research distinction: Anxiety, stress, and mood-related cognitive impairment research vs. Stroke recovery, neuroprotection, or cognitive performance enhancement research focused on BDNF mech.
What is the key difference between Selank and Semax?
Selank (tuftsin analog) targets anxiety via GABA/serotonin modulation; semax (ACTH4-7 analog) targets cognitive enhancement and neuroprotection via BDNF - the distinction matters for application-specific research.
Evidence Comparison
Both: approved in Russia, Russian RCT data, no Western regulatory review. Semax has the more robust stroke indication (Lebedeva 2008 multicenter RCT n=60). Selank's anxiolytic RCT is smaller (Semenova 2010, n=38). Both face the same Western validation gap.
Evidence Context Favoring Selank
Anxiety, stress, and mood-related cognitive impairment research.
Evidence Context Favoring Semax
Stroke recovery, neuroprotection, or cognitive performance enhancement research focused on BDNF mechanisms.
