Semax vs. Selank: Two Nootropic Research Peptides Compared
Semax and Selank are both short synthetic peptides developed at the Institute of Molecular Genetics in Russia, and both are studied in the nootropic space — but they come from different parent molecules and are researched for different things.
SEMAX
Semax is a 7-amino-acid analog of a fragment of ACTH (adrenocorticotropic hormone), modified for stability. Research has focused on cognition, attention and neuroprotection, including its influence on BDNF (brain-derived neurotrophic factor) expression.
SELANK
Selank is a 7-amino-acid analog of tuftsin, an immune-modulating peptide. It is mostly studied for anxiolytic (stress-reducing) effects and mood, with research also touching on immune signaling.
SIDE BY SIDE
- Parent molecule: Semax — ACTH fragment; Selank — tuftsin
- Primary research focus: Semax — cognition and neuroprotection; Selank — stress and anxiety
- Both: short, stabilized heptapeptides supplied as lyophilized powder
