# Selank and Semax: The Complete Protocol for Calm Focus and Cognitive Enhancement
Selank and Semax are two of the most studied nootropic peptides in the Russian pharmacological research tradition — and they've earned a dedicated following in the biohacking community for good reason. They're both intranasal, fast-acting, and well-tolerated. But they do very different things, which is why the question of how to use them together matters.
This guide covers both compounds individually, then explains the best protocols for combining them.

What Is Semax?
Semax is a synthetic heptapeptide derived from ACTH (adrenocorticotropic hormone). It was developed in Russia in the 1980s and is registered as a pharmaceutical there for stroke recovery, cognitive impairment, and ADHD.
Mechanism of action:
Increases BDNF and NGF expression
Upregulates dopaminergic and serotonergic signaling
Modulates the HPA axis (stress response)
Enhances working memory and attention via prefrontal cortex activity

What Is Selank?
Selank is a synthetic hexapeptide derived from Tuftsin. Also developed in Russia, where it's registered as an anxiolytic and nootropic.
Mechanism of action:
Modulates GABA-A receptor activity
Regulates enkephalins and endorphins
Increases BDNF expression
Downregulates stress-response hyperactivation in the amygdala

Semax vs. Selank: Core Difference
Semax sharpens. Selank calms. Run together, they create a "calm focus" state that many people find more effective than either alone.

Protocol Options
Option 1: Stack Together (AM — Calm Focus)
Semax: 100–200mcg per dose
Selank: 250mcg per dose
Timing: 5–15 minutes before starting work
Option 2: Split AM/PM
Morning: Semax 200–300mcg
Evening: Selank 250–500mcg
Option 3: Situational Use
Semax before high-stakes work or creative sessions
Selank before stressful events or on high-anxiety days
