Cognitive Enhancement Stack
Nootropic peptides for focus and resilience


Why This Stack Works
Semax upregulates BDNF and stimulates dopamine/serotonin pathways for focus and memory. Selank modulates GABAergic activity for anxiolysis and mental clarity. Complementary nootropic profiles with no overlap in mechanism.
This combination draws from Cognitive research, targeting cognitive, nootropic, BDNF, neuroprotection, focus, memory. The compounds in this stack act on distinct receptor systems and biological pathways, making them suitable for combined use without mechanism overlap.
All compounds in this stack are supplied by Phiogen with independent third-party Certificate of Analysis (COA) documentation confirming 99%+ purity. They are sold strictly for laboratory and educational use only and are not FDA-approved for human therapeutic use.
Research Protocol
Semax: 100β300 mcg intranasal 1β2Γ/day. Selank: 250β500 mcg intranasal 1β2Γ/day. 2β4 week cycles with breaks.
