Best Peptide Stack for Brain & Cognition

Enhanced Semax with modifications for better absorption and potency. Stronger BDNF boost with longer-lasting cognitive benefits.

Brain-repair peptide blend from pig brain tissue containing natural nerve growth factors. Used for stroke and TBI recovery in 50+ countries. Strongest RCT evidence of any brain peptide.

Brain-boosting peptide that increases BDNF by ~1.4x at the protein level and up to 3x at mRNA level in animal studies. Promotes neurogenesis, improves cerebral blood flow. Used clinically in Russia for stroke recovery and cognitive decline.

Rapid-acting antidepressant peptide. Inhibits TREK-1 potassium channels, boosting neuronal excitability and triggering fast BDNF upregulation. Mouse studies show antidepressant effects within days.

Enhanced Selank with better stability and bioavailability. Delivers stronger anxiolytic and immune-boosting effects than regular Selank.

Brain booster enhancing dopamine systems and promoting nerve branch growth. Works through a unique mechanism. Must avoid sun/UV exposure while using.

Russian anxiolytic peptide working on GABA, serotonin, and enkephalin systems. Eases anxiety without sedation or dependence risk. Also boosts immunity. Decades of clinical use.

Engineered to target inner mitochondrial membrane via cardiolipin binding. Stabilizes cristae, improves ATP production, and reduces oxidative stress. FDA-approved for Barth syndrome (as Forzinity) — the first FDA-approved mitochondria-targeted therapy.

Critical molecule for cellular energy and DNA repair. Levels may drop ~50% by middle age. Activates sirtuin longevity genes and powers PARP DNA repair enzymes. Injectable form bypasses oral absorption issues.
