Research comparison

Semax vs Selank

Semax and Selank are short regulatory peptides studied in neuro and behavioral research. Both originate from Russian peptide research programs but derive from different parent molecules and are investigated for different signaling questions.

Aspect	Semax	Selank
Parent molecule	ACTH(4-10) fragment analog	Tuftsin analog
Primary research focus	Neurotrophic & cognitive-signaling models	GABAergic & immunomodulatory models
Signaling studied	BDNF / neurotrophic pathways	GABAergic & cytokine pathways
Format / purity	Lyophilized · ≥99% HPLC	Lyophilized · ≥99% HPLC

Different parents, different questions

Semax is an ACTH(4-10) fragment analog studied largely around neurotrophic signaling (including BDNF-related pathways), while Selank is a tuftsin analog investigated more for GABAergic and immunomodulatory questions. Researchers choose between them based on the pathway under study.
