Selank vs Semax
An educational, source-based comparison of Selank and Semax — how each peptide works, what it's researched for, and what to know before going deeper.
A synthetic analog of the immunomodulatory peptide tuftsin. Research suggests it modulates GABAergic and serotonergic systems and influences expression of brain-derived neurotrophic factor without the sedation or dependence profile of benzodiazepines.
- Generalized anxiety models
- BDNF expression
- Immune modulation
- Memory and learning in rodent models
- • Not FDA-approved.
- • Most studies are Russian clinical literature.
A synthetic heptapeptide derived from ACTH(4-10). Research suggests it modulates BDNF and NGF expression, dopaminergic and serotonergic tone, and shows neuroprotective effects in ischemia models.
- BDNF/NGF upregulation
- Ischemic stroke recovery (clinical use in Russia)
- Attention and cognitive performance
- Anxiolytic-style effects
- • Approved as a medication in Russia; not FDA-approved in the US.
- • Most clinical literature is in Russian.
Selank vs Semax — Key differences
- Class: Selank is classified as Anxiolytic · Nootropic, while Semax is Nootropic · Neuroprotection.
- Primary research focus: Selank — generalized anxiety models; Semax — bdnf/ngf upregulation.
- Tag: Calm · Cognition vs Cognition.
