- Before integrating this stack, understanding how each peptide contributes individually versus synergistically clarifies why the combination outperforms single-compound protocols.
- Selank
- Enkephalin modulation + substance P stabilisation
- GABAergic, serotonergic, immune
- Reduces anxiety without sedation; lowers cortisol; improves emotional regulation
- ~30 minutes (intranasal)
- 300–600 mcg 1–2x daily
- Clears the interference pattern. Removes the cortisol brake on memory consolidation and executive function
- Semax
- Melanocortin receptor agonism (MC4R)
- BDNF, NGF upregulation
- Enhances neuroplasticity, synaptic efficiency, cerebral blood flow
- 70 minutes (standard); 4–6 hours (Amidate)
- 600–900 mcg 1–2x daily (standard); 300–600 mcg (Amidate)
- Amplifies the signal. Drives neurotrophic factor expression and long-term potentiation when cortisol interference is minimised
- Combined Stack
- Dual-pathway modulation
- Anxiolytic + neurogenic
- Synergistic cognitive enhancement. Memory retention improved 24–31% vs baseline
- N/A
- Selank 300–600 mcg + Semax 600–900 mcg, sequential dosing
- The only nootropic stack where clinical evidence supports true synergy rather than additive redundancy
