Protocol rationale
Selank
Selank
Preclinical research on Selank (TP-7) in rodent models has reported anxiolytic and mild cognitive-enhancing effects via GABAergic modulation and BDNF upregulation, without notable motor impairment. Reported research protocols use intranasal dosing of approximately 250–750 mcg/day. No controlled human efficacy trials are published outside the Russian-language literature.

Semax
Preclinical research on Semax (ACTH(4-7) PGP) in rodent models reports BDNF and NGF upregulation in the prefrontal cortex and hippocampus, with neuroprotective effects in ischaemia models. The compound is used clinically in Russia for stroke and cognitive impairment; published research protocols use approximately 300–600 mcg/day intranasal.
