Overview
A tuftsin-based peptide developed in Russia and used there clinically for anxiety — notable for reports of calm without sedation or dependence, which is what draws nootropic users. Like Semax, its regional clinical history outpaces independent Western trials.
Mechanism
Modulates GABA/serotonin systems with tuftsin-like immunomodulation in the originating research; the non-sedating anxiolytic profile is its signature claim.
Evidence
Regional clinical use and human studies support the anxiolytic effect; independent RCT replication is limited.
