Semax + Selank

Also known as: Nootropic Stack, Cognitive Stack, Russian Nootropic Stack

The established nootropic peptide duo combining a focus/neuroplasticity peptide with an anxiolytic peptide for 'calm focus.'

Components

How it's combined

Research framing: Semax upregulates BDNF to support focus, memory consolidation, and neuroplasticity, while Selank modulates GABAergic activity and stabilizes enkephalins to reduce anxiety without sedation, smoothing the stimulating edge of Semax. Both were developed at the same Russian institute and are most commonly administered intranasally (subcutaneous also used).
