Selank vs Semax

Anxiolytic versus nootropic heptapeptides. Here is how the two research peptides compare on class, format and price.

Selank

Selank is a synthetic heptapeptide derived from the immunomodulatory peptide tuftsin. It is supplied lyophilised in a 10 mg vial for laboratory and in-vitro research use only.

Selank is studied for anxiolytic and neuromodulatory activity in behavioural-research models, and is often examined alongside Semax.

Semax

Semax is a synthetic heptapeptide derived from a fragment of ACTH. It is supplied lyophilised in a 10 mg vial for laboratory and in-vitro research use only.

Semax is studied for nootropic and neuroprotective activity, including BDNF-related signalling, in cognition-research models, and is frequently paired with Selank.

Which do researchers choose?

Selank and Semax are anxiolytic versus nootropic heptapeptides. The right choice depends on the research question: they differ in class (Anxiolytic heptapeptide vs Nootropic heptapeptide) and strength (10 mg vs 10 mg). Both are supplied lyophilised, third-party HPLC tested, and shipped express post Australia-wide for laboratory and in-vitro research use only.
