Cognitive Enhancement Stack

Published August 27, 2026 1 min read Semax 30mg + Selank 5mg + Dihexa 100mg Nootropic

Overview

Each peptide targets a distinct pathway. Semax rapidly upregulates BDNF and NGF within hours. Selank reduces anxiety-related cognitive impairment and modulates serotonin. Dihexa drives lasting structural changes u2014 increasing synaptic density and dendritic arborisation u2014 over days to weeks. Together they provide immediate performance enhancement (Semax/Selank) and lasting structural improvement (Dihexa).

Dosing & Reconstitution Guide

See individual protocols u00b7 See individual protocols u00b7 Half-life: Semax ~1 min / Selank ~1 hr / Dihexa weeks

Reconstitution Table (Multiple mL BAC water u2192 Multiple)

Compound Dose Route
Semax 200u2013400 mcg Intranasal (morning)
Selank 250 mcg Intranasal (as needed for anxiety)
Dihexa 30u201360 mg Oral (daily or every other day)

Semax and Selank can be administered intranasally in the morning. Dihexa is taken orally. Given Dihexa's exceptionally long duration, consider every-other-day dosing to avoid accumulation.

This is an aggressive nootropic stack. Start each compound individually before combining. Dihexa has minimal human safety data u2014 proceed cautiously. Research use only.
