Nootropic Peptides Compared

Nootropic and anxiolytic research peptides act on distinct neurotransmitter systems. Semax (and its acetylated derivatives) up-regulate BDNF and modulate dopaminergic signaling; Selank acts on the GABA-ergic and tuftsin-mimetic anxiolytic pathways; DSIP (Delta-Sleep-Inducing Peptide) modulates EEG delta-wave activity and stress-response cortisol.

All compounds ship lyophilized. Available CertikLabs lot reports are linked from the relevant product page.
