Cognitive Enhancement
Nootropic peptides and neuro-support protocols for focus, memory, and brain health.
About this treatment area
Cognitive peptide protocols use compounds like Semax and Selank (Russian-developed, registered medicines in Russia but unapproved in the US), Dihexa, and Cerebrolysin. Evidence is thinner here than in weight or hormone categories. Reputable clinics frame these as experimental.
