Selank
Mechanism.
Selank is a synthetic peptide developed at the Institute of Molecular Genetics of the Russian Academy of Sciences. It is a synthetic analogue of the naturally occurring immunomodulatory peptide tuftsin (a tetrapeptide produced by enzymatic cleavage of IgG) with an added Pro-Gly-Pro sequence for stability. Selank is approved in Russia as an anxiolytic and nootropic medication. It has not undergone clinical trials for FDA approval.
Selank is like a two-for-one supplement that works on both your brain and immune system. For your brain, it calms anxiety by boosting your natural feel-good molecules (enkephalins) and protecting them from being broken down too quickly. For your immune system, it fine-tunes the balance between different immune responses.
