Selank & Semax: A Neuropeptide Research Overview

Selank and Semax are two synthetic neuropeptides studied in cognitive and neuroregulatory research. This overview explains each, how they differ, and how to source research-grade material.

What is Selank?

Selank is a synthetic heptapeptide (seven amino acids) derived from the immunomodulatory peptide tuftsin. It is studied primarily in anxiolytic and neuropeptide-pathway research.

What is Semax?

Semax is a synthetic peptide derived from a fragment of ACTH. It is studied in cognitive, neuroprotective and BDNF-pathway research models.

How they differ

Both are neuropeptides, but they're studied along different lines: Selank is more associated with anxiolytic/neuropeptide research, while Semax is associated with cognition and neurotrophic-factor research. They're often grouped together in the same research category.

Formats & products

Both sit within the Cognitive & Sleep collection, alongside DSIP.

Handling, reconstitution & purity

Reconstitute lyophilized vials with bacteriostatic water per our reconstitution guide. All material is ≥98% HPLC-verified, documented on the Quality & COA page.

Manufacturing & Quality

Alpha Biologix supplies Selank and Semax under pharmaceutical-grade manufacturing standards: each batch is produced to ≥98% HPLC-verified purity and independently tested by a third-party laboratory. A batch-specific Certificate of Analysis (COA) is available for every lot, giving researchers verifiable documentation of identity and purity before use.
