PHYSIOLOGICAL OBJECTIVE
Peptides for Cognitive Enhancement & Nootropics
Synthetic neuropeptides that cross the blood-brain barrier to upregulate Brain-Derived Neurotrophic Factor (BDNF), enhance memory consolidation, and reduce central neuro-inflammation.

🏆 Ranked Peptides for Peptides for Cognitive Enhancement & Nootropics
| Peptide | Efficacy Tier | Clinical Rationale | Dosage Summary |
|---|---|---|---|
| Semax | Gold Standard | ACTH(4-10) analogue that dramatically increases BDNF, TrkB, and dopamine/serotonin neurotransmission. | 200mcg - 600mcg intranasal or subcutaneous in the morning. |
| Selank | Gold Standard | Tuftsin-derived anxiolytic peptide that modulates GABA-A receptors and suppresses systemic IL-6 inflammatory cytokines. | 250mcg - 500mcg intranasal 1-2 times daily. |
| Dihexa | High Efficacy | Angiotensin IV analogue that exhibits picomolar affinity for HGF, stimulating synaptogenesis 7 orders of magnitude more potent than BDNF. | 5mg - 10mg oral or transdermal 2-3 times per week. |
📋 Clinical Protocol Recommendation
Combine Semax (morning focus) with Selank (afternoon calm & neuroprotection) for clean cognitive performance without central nervous system overstimulation.
Frequently Asked Questions
❓ Are Semax and Selank administered via injection or nasal spray?
Both peptides are exceptionally effective via intranasal delivery due to direct olfactory mucosal transport to the central nervous system, though subcutaneous injection is also common.
