SEL-ank
A Russian-developed synthetic peptide that reduces anxiety and supports immune function — based on the body's natural tuftsin molecule.
Also known as: TP-7
Last reviewed: April 2026
Selank is a synthetic analog of tuftsin (a naturally occurring immune peptide) with added amino acids for stability. It modulates GABA, serotonin, and dopamine systems to reduce anxiety and enhance focus — without sedation or addiction potential. Also has documented immune-modulating properties.

Selank is more anxiolytic (calming). Semax is more stimulating (focus/energy). Often used together. Both are Russian-developed nasal peptides.
Semax
A synthetic brain peptide derived from ACTH that enhances focus, memory, and neuroprotection — developed in Russia.
Dihexa
A potent cognitive peptide that promotes new brain connections — millions of times more potent than BDNF at stimulating neural growth.
