Semax vs Selank

Two Russian-developed nootropic research peptides studied for neuroactive properties via distinct pathways.

Semax derives from an ACTH fragment and is studied around BDNF/neurotrophic signaling.
Selank derives from tuftsin and is studied around GABA/monoamine systems.
Both are sold strictly for laboratory research use only.

Semax

A synthetic peptide derived from a fragment of ACTH, studied in neuroscience research, particularly in Russian literature.

Selank

A synthetic analog of the immunomodulatory peptide tuftsin, studied in neuroscience and anxiety-model research.
