Description
Selank + Semax Nasal Spray — Neuropeptide Pair for CNS Research
What is this combination spray?
This nasal spray contains two synthetic heptapeptides widely used in neuropeptide research: Selank (Thr-Lys-Pro-Arg-Pro-Gly-Pro) and Semax (Met-Glu-His-Phe-Pro-Gly-Pro). Both peptides are derived from naturally occurring regulatory sequences — Selank from tuftsin and Semax from ACTH(4-10) — and are studied for their effects on the central nervous system.
Selank is investigated for anxiolytic-like (anxiety-modulating) properties and its influence on the enkephalin and serotonin systems, while Semax is studied as a nootropic peptide for cognitive enhancement, neuroprotection and BDNF-related neuroplasticity. This combined nasal spray kit delivers both peptides as lyophilised powder, with a metered-dose spray bottle and bacteriostatic water for reconstitution — a complete kit for comparative CNS peptide studies.
Mechanism of Research Interest
- Selank — Anxiolytic-like Activity: Studied for modulation of anxiety-related behaviour and interaction with the endogenous enkephalin degradation system.
- Selank — Serotonergic Effects: Research examines effects on serotonin metabolism and turnover in brain tissue models.
- Semax — Nootropic Activity: Investigating for effects on learning, memory and attention in behavioural research models.
- Semax — Neuroplasticity: Studied for upregulation of BDNF and modulation of synaptic plasticity markers.
- Combined Research Value: Provides both peptides in one spray for comparative neuropeptide studies and protocol flexibility.
Research Applications
- Anxiety and stress behaviour research
- Cognitive function and memory studies
- BDNF and neuroplasticity research
- Neuropeptide pharmacokinetic comparison
- Intranasal peptide delivery research

Quality & Sourcing
All Cronopharm research products are sourced from reputable manufacturers and undergo quality verification. Each batch is tested for purity using HPLC analysis. We maintain strict cold-chain handling from warehouse to dispatch to ensure product integrity throughout the supply chain.
Key Research Benefits
- Dual Neuropeptide Research: Selank (anxiolytic-like) and Semax (nootropic) in one spray for comparative CNS studies.
- Intranasal Delivery: Reconstituted solution is transferred to the metered-dose spray bottle for nasal route bioavailability research.
- Combined Protocol Flexibility: Both peptides in a single format simplifies comparative study design.
- Complete Kit: Includes lyophilised peptide vial, spray bottle and bacteriostatic water — everything needed for intranasal research protocols.
How to Use (Research Application)
For experienced laboratory personnel only. This product is supplied as a lyophilised kit and must be reconstituted before use.
- Allow the peptide vial to equilibrate to room temperature. Wipe the rubber stopper with an alcohol swab.
- Using a sterile syringe, inject the supplied Bacteriostatic Water slowly down the inner wall of the vial.
- Gently swirl until the powder is fully dissolved — do not shake, as this can denature the peptide.
- Draw the reconstituted solution into a sterile syringe and transfer it into the empty metered-dose nasal spray bottle.
- Reattach the spray nozzle and prime the pump 2–3 times until an even mist is produced.
- Follow the administration schedule defined in your research protocol. Store at 2–8°C and use within the timeframe defined in your protocol.
