Semax & Selank: The Frontier of Nootropic Peptides

Comparing the mechanisms of ACTH-derived analogues in cognitive enhancement and anxiolytic models.

### Semax: Cognitive Clarity Derived from Adrenocorticotropic Hormone (ACTH), Semax has been studied for its neuroprotective and neurogenic properties. Research suggests it increases Brain-Derived Neurotrophic Factor (BDNF) levels, potentially enhancing memory consolidation, focus, and protection against oxidative stress in neuronal tissue. ### Selank: Anxiolytic Modulation Selank is also an ACTH analogue but with a focus on anxiety regulation. It appears to modulate the expression of Interleukin-6 and balance neurotransmitters like serotonin and dopamine. Research models show it may reduce anxiety without the sedation typical of benzodiazepines. ### Research Focus Both peptides are heavily researched for their potential in treating ischemic stroke damage, ADHD, and anxiety disorders. *Advance your neuroscience research with peptides from peptide limited.*
