What does Selank peptide do?

In research models, Selank is studied mainly for anxiety and stress behavior. It’s a seven-residue synthetic peptide (Thr-Lys-Pro-Arg-Pro-Gly-Pro) built on tuftsin, an immune peptide, with a Pro-Gly-Pro tail added for stability. In rats under chronic mild stress, Selank improved anxiety measures, and intranasal Selank raised BDNF in the hippocampus. Its effects on anxiety appear to involve GABA signaling and enkephalin breakdown.

Small Russian clinical studies reported anxiety reductions similar to a benzodiazepine, with less sedation, but they had small groups and limited blinding. Selank is registered in Russia and isn’t FDA approved. Other work covers learning, memory and immune signaling in rodents. Labs studying both peptides from the same institute can compare the Selank / Semax blend. Shop Selank Peptide.
