youtube 2026-06-07 source →
Supplement formulator compares neuropeptides to traditional nootropics. Dihexa described as 'hundreds of times more powerful than lion's mane' for neurogenesis. P21+Dihexa combined in 'Neurorigen' product. Semax compared to alpha-GPC but far more potent. All peptides positioned as tools to combat neurodegenerative disease beyond what supplements alone can achieve. Also discusses dopamine resensitization via Semax, P21, Dihexa.
