Per-milligram prices for 10 cognitive enhancement & neuroprotection compounds, read automatically from public storefronts across shops with third-party lab tests on file. Prices exclude shipping, taxes and customs. Browse six cognitive enhancement and neuroprotection peptides tracked on Peptigrity, with verified third-party HPLC purity data, shop coverage, and mechanism research for each. The category covers four mechanism classes: ACTH-derived nootropics (Semax, Selank), the sleep-regulating neuropeptide DSIP, the social and stress-modulating peptide oxytocin, and microtubule-stabilizing neuroprotective peptides (Adamax/davunetide, P21). Most compounds in this category have substantial Russian-language research bases with limited Western RCT replication.

Per-milligram cost falls as vial size rises, so compare within a size band rather than across the whole list — the lowest figure on a compound is often a bulk vial. Read the cognitive enhancement & neuroprotection guide for what these compounds are and how they are tested.
