Cognitive Stack
Neuropeptide Cognitive Stack.
Three Russian-origin neuropeptides — Selank, Semax and DSIP — structured as one bundle covering anxiolytic, BDNF and sleep-architecture research pathways.
Fresh-batch only — per-batch COA included with every shipment.
Why It Works
Built for the fastest neuropeptide research decision.
Anxiolytic angle
Selank is the canonical Russian-origin anxiolytic-research peptide — tuftsin-derived, GABA-system literature.
BDNF angle
Semax (ACTH(4-10) analog) anchors the BDNF-expression and neurotrophic-factor research framing.
Sleep-architecture angle
DSIP (Delta Sleep-Inducing Peptide) is the reference compound for slow-wave-sleep and circadian-rhythm research.
Stack Composition
The three compounds anchoring the offer.
Each compound is available standalone in the shop — the stack bundles them at flagship positioning.

FAQ
Clear answers remove hesitation.
Which cognitive tier fits me?
Starter (Selank alone) for the anxiolytic-research entry. Advanced adds Semax for the BDNF-expression angle. Ultimate adds DSIP for the sleep-architecture layer.
Why these three compounds?
Selank, Semax and DSIP are all of Russian/Soviet-origin neuropeptide research. Together they cover the three most-cited mechanisms in their corpus — anxiolytic, BDNF and slow-wave-sleep.
How does shipping work?
Tracked dispatch with neutral, discreet packaging. Fresh-batch model: 14–21 days transit, per-batch COA included.
