Focus & Neuroprotection Stack
BDNF amplification with cognitive and mood support.
Combines the nootropic triad of Semax (ACTH analogue), Selank (anxiolytic), and Dihexa (HGF/MET pathway, synaptogenesis). This stack targets BDNF, NGF, and HGF simultaneously.
What's in this stack
Research Protocol
- Semax: 300 mcg intranasal AM
- Selank: 250 mcg intranasal twice daily
- Dihexa: 10–15 mg oral daily

Frequently Asked Questions
What makes Semax and Selank different from other nootropic research compounds?
Semax is an ACTH-derived peptide that upregulates BDNF and VEGF in the prefrontal cortex, while Selank is a synthetic analogue of tuftsin with anxiolytic and memory-enhancing properties. Both are endogenous-pathway compounds rather than receptor agonists.
Can cognitive peptides be taken in oral capsule form?
Semax and Selank are traditionally studied as nasal sprays or injectables due to blood-brain barrier considerations. Dihexa and 5-Amino-1MQ have demonstrated oral bioavailability in research and are available as capsules.
What is the research rationale for combining Semax and Selank?
Semax addresses cognitive enhancement and BDNF upregulation while Selank modulates anxiety and enkephalin metabolism. Research suggests their combined use may address both the cognitive and anxiolytic axes of nootropic research without overlap.
How long are cognitive peptide research cycles?
Cognitive peptide research typically uses 10–14 day cycles with equal rest periods, based on published neurotrophin regulation studies. Longer continuous use has not been well characterised in the available literature.
