The Cognitive Stack Nasal Kit from NXTSTATE pairs two research-grade nasal DIY kits, Semax and Selank, into a single research bundle. Each kit ships with all hardware needed to reconstitute and prepare the compound on-site. Both vials are tested at ≥99% HPLC purity, with a third-party Certificate of Analysis included on every lot. The Cognitive Stack Nasal Kit is sold at a 15% discount versus purchasing the two nasal kits individually.

What the Cognitive Stack Nasal Kit Includes

Semax Nasal Kit:

• 1 × Semax 10mg lyophilized vial
• 1 × 5ml sterile saline diluent
• 1 × 10ml empty nasal spray bottle
• 1 × assembly pouch

Selank Nasal Kit:

• 1 × Selank 10mg lyophilized vial
• 1 × 5ml sterile saline diluent
• 1 × 10ml empty nasal spray bottle
• 1 × assembly pouch

Lot-specific Certificate of Analysis for each compound is available from the NXTSTATE Lab Reports library.

Semax Research Background

Semax is a synthetic heptapeptide derived from a fragment of adrenocorticotropic hormone (ACTH 4-10). It was originally developed in Russia and remains the subject of an active body of preclinical and clinical research literature. Investigators have studied Semax for its effects on BDNF (brain-derived neurotrophic factor) and NGF (nerve growth factor) expression, dopaminergic and serotonergic signaling, attention and working memory in rodent models, and post-ischemic neuroprotection. A summary of published literature is indexed on PubMed.

Selank Research Background

Selank is a synthetic heptapeptide derived from a fragment of the immunomodulatory peptide tuftsin. It is most often studied for its anxiolytic profile, modulation of GABAergic transmission, enkephalin enzyme inhibition, and effects on interleukin signaling and stress-response behavior in rodent models. Published Selank literature is indexed on PubMed.

Why the Cognitive Stack Nasal Kit Is Bundled

Semax and Selank are frequently studied together because their mechanisms are complementary. Semax is most often characterized for activation, neurotrophic-factor expression, and cognitive enhancement endpoints, while Selank is most often characterized for anxiolytic, anti-stress, and immunomodulatory endpoints. The nasal kit format is favored in research settings that prioritize precision dosing and reproducible delivery volumes. Bundling both nasal kits as the Cognitive Stack Nasal Kit reduces per-compound cost and ensures researchers receive matched-lot inventory in a single shipment.

Quality Standards

• ≥99% HPLC purity on both compounds (independently verified)
• Third-party lab tested with Certificate of Analysis on every lot
• Lyophilized for storage stability and predictable reconstitution
• Sealed and shipped from NXTSTATE
• Lot tracking enabled for audit and reproducibility

Handling and Storage

Both vials ship lyophilized and may be stored at room temperature for a short period after arrival. Long-term storage prior to reconstitution is recommended at refrigeration temperatures (2 to 8 degrees Celsius). Once reconstituted with the included sterile saline diluent, both peptides should be refrigerated and used within the timeframe outlined in standard peptide handling references.

Important: Research Use Only

The Cognitive Stack Nasal Kit is sold strictly for in vitro research, laboratory analysis, and preclinical investigation. It is not a medicine, supplement, or cosmetic. It is not intended for human or veterinary consumption, ingestion, or administration. By purchasing this product, you confirm you are a qualified researcher and that all materials will be handled in accordance with applicable laws and institutional protocols.
