The Cognitive Stack Nasal Kit combines two complete research nasal kits, Semax and Selank, into one convenient package. Each kit includes a 10mg lyophilized peptide vial, sterile saline diluent, an empty nasal spray bottle, and an assembly pouch.

Both peptides are tested at ≥99% HPLC purity, with batch-specific third-party analytical documentation available for research verification.

What’s Included

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

Each peptide is supplied separately, allowing researchers to prepare and evaluate the compounds independently.

Research Overview

Semax is a synthetic heptapeptide derived from the ACTH 4–10 fragment. Research has examined its relationship with BDNF and NGF signaling, neurotransmitter pathways, neuroprotection models, and cognition-related endpoints.

Selank is a synthetic heptapeptide analog of tuftsin. It has been investigated in studies involving GABAergic signaling, stress-response pathways, cytokine activity, and neurobiological mechanisms.

Researchers can explore published literature for Semax and Selank through PubMed.

Kit Advantages

The Cognitive Stack Nasal Kit is designed for research programs that require both compounds in a consistent, organized format. Each peptide remains lyophilized until preparation, while the included components provide the basic hardware needed for laboratory assembly.

The bundle also simplifies procurement by combining the two individual nasal kits into one order.

Quality & Documentation

• ≥99% HPLC purity specification for each peptide
• Third-party analytical testing
• Batch-specific Certificate of Analysis
• Mass spectrometry identity verification
• Individual lot tracking
• Lyophilized peptide presentation

Researchers can review applicable batch documentation through the Lab Reports library.

Storage & Handling

Keep unopened lyophilized vials protected from excessive heat, moisture, and direct light. Follow the storage conditions provided with the applicable product documentation.

The included saline and spray components should remain sealed until required for the approved laboratory procedure. Once prepared, researchers should follow their established laboratory handling and storage protocols.

Product Specifications

Frequently Asked Questions

What is included in the Cognitive Stack Nasal Kit?

The bundle contains one complete Semax nasal research kit and one complete Selank nasal research kit, including the peptide vials, saline diluents, empty spray bottles, and assembly pouches.

Are the Semax and Selank supplied in the same vial?

No. Each peptide is provided in its own individually sealed vial for separate laboratory preparation.

What purity are the peptides tested to?

Both Semax and Selank are specified at ≥99% HPLC purity and supported by batch-specific analytical documentation.

Is this a ready-to-use nasal spray?

No. The kit contains separate components for laboratory preparation and assembly. It is not supplied as a finished nasal formulation.

Is the kit intended for human use?

No. The Cognitive Stack Nasal Kit is supplied strictly for laboratory research and is not intended for human or veterinary administration.

Research Use Only

This product is intended exclusively for qualified laboratory research, analytical work, and permitted preclinical investigation. It is not intended for human or veterinary consumption, administration, diagnosis, treatment, or prevention of disease.

Purchasers are responsible for ensuring appropriate handling and compliance with applicable institutional and regulatory requirements.

For laboratories researching Semax and Selank together, the Cognitive Stack Nasal Kit provides both research formats in one streamlined package.
