Selank
is a peptide developed in Russia as an anxiolytic and nootropic; in animal models it reduces anxiety-like behavior and modulates immune parameters under stress
7 amino acids
Semax
is used clinically in Russia for ischemic stroke and cognitive disorders; in models it improves learning, protects dopaminergic neurons, and modulates stress responses without significant endocrine ACTH-like effects
9 amino acids
DSIP
was originally described for inducing spindle and delta sleep activity when infused into the brain of rabbits; later studies report stress-modulating and endocrine effects, though its physiological role is still debated
6 amino acids
