§ 01 — Context
Russian-developed nootropic peptides (semax, selank) and angiotensin IV analogues (dihexa) are the cognition stack's anchor compounds. Most are nasal-spray or injectable, with rapid CNS penetration.
Cognitive-enhancement peptides are the most subjective category — what 'works' depends on baseline. We surface dosing protocols and route-of-administration alongside price so you compare like-for-like.
What to look for
01Route of administration (nasal vs subcutaneous) drives bioavailability
02Stacking pairings — Selank balances Semax's stim profile
03Reputable Russian-source supply chain (post-2022 disruption matters)
04Cycle length — nootropic peptides are not lifetime compounds
