This comprehensive nootropic capsule represents a multi-pathway approach to cognitive optimization, combining four research compounds with distinct and complementary mechanisms. Dihexa (PNB-0408) is an angiotensin IV analog reported to be approximately 10 million times more potent than BDNF at promoting synaptogenesis in the hippocampus. Selank is a heptapeptide analog of tuftsin developed at the Institute of Molecular Genetics in Russia, where it received regulatory approval for the treatment of anxiety disorders; it modulates GABAergic and serotonergic systems while also upregulating BDNF. Semax is a synthetic analog of ACTH(4-7) developed in Russia, where it is approved for use in stroke and cognitive impairment; it directly upregulates BDNF and NGF while activating dopaminergic and serotonergic pathways. NAD+ (nicotinamide adenine dinucleotide) is a fundamental coenzyme involved in over 500 enzymatic reactions, with particular importance in mitochondrial energy production and sirtuin-mediated gene regulation. Together, these four compounds address synaptogenesis, anxiolysis, neurotrophic factor upregulation, and cellular bioenergetics simultaneously.
