Selank is a synthetic heptapeptide based on the immune peptide tuftsin. It's studied mainly as an anxiolytic research peptide and for its effects on cognition.
Mechanism
Selank acts on several pathways tied to anxiety, including the opioid system, and in research it has been shown to modulate the activity of other anxiolytic compounds (Seredenin et al., 2012). Its anxiolytic and cognitive effects were examined by Kasian et al. (2017) and Volkova et al. (2018).
