Semax vs Selank
Semax and Selank are the two most-studied nootropic research peptides, compared because they are investigated in overlapping cognitive and neuro-research contexts through different proposed mechanisms.
Semax
ACTH fragment analogue — cognitive and neuroprotective research peptide.
Selank
Synthetic heptapeptide analogue derived from tuftsin — supplied for in-vitro neurochemical and receptor-model research.
| Semax | Selank | |
|---|---|---|
| Origin | Synthetic ACTH(4-10) fragment analogue | Synthetic tuftsin analogue |
| Research area | BDNF/neurotrophic pathway models | Anxiolytic and GABA/immune pathway models |
| Studied focus | Cognitive and neuroprotection research | Stress-response and calm-focus research |
| Format | Lyophilised, water-soluble | Lyophilised, water-soluble |
Common questions
What is the difference between Semax and Selank?
Semax research centres on BDNF and neurotrophic pathways in cognitive models, while Selank research focuses on anxiolytic and immune-modulating pathways. They are frequently studied in the same nootropic research context through these different mechanisms.
