Semax vs Selank: Neuropeptide Research Comparison

Semax and selank are two of the most frequently compared neuropeptides in published research literature. Both originate from Russian peptide research programs and both have generated wide research interest. This page compares the two for investigators sourcing material for laboratory research.

Background on each compound

Semax is a synthetic heptapeptide originally derived from a fragment of ACTH(4-10) and is referenced in cognitive and neuroprotective research literature. Selank is a synthetic heptapeptide derived from tuftsin and is referenced in anxiolytic and immune research literature. Their published research footprints overlap but emphasise different endpoints.

Research models in literature

Semax appears in cognitive and neuroprotection research models; selank appears in anxiolytic and stress-response research models. Investigators reference published literature when designing study protocols. Amino Fuel Labs makes no human-use claims for either compound.

Lot documentation

Both peptides are third-party HPLC verified at release and shipped with a Certificate of Analysis. COAs document identity, lot, manufacture and retest dates, appearance, and purity, with vial labels matching COA lot numbers.

Selecting between them

Cognitive-focused research models often reference semax; anxiolytic and stress-response research models often reference selank. Both are research use only. Information here is research peptide information, not medical guidance.
