What Is the Semax + Selank Spray?
Semax and Selank are two Russian-developed heptapeptides that share a stabilising C-terminal Pro-Gly-Pro tail but derive from different parent molecules: Semax from the ACTH(4–7) fragment, Selank from the immunomodulatory tetrapeptide tuftsin. They are frequently studied side by side in neuropeptide research, and this spray supplies both in one preserved solution at a fixed 1:1 ratio.
The ready-to-use format is designed for intranasal-delivery models, transmucosal transport assays and other protocols that call for a metered aqueous peptide solution rather than a lyophilised vial. Researchers who need the peptides separately or at different concentrations can choose our Semax 10mg and Selank 10mg lyophilised vials.
Semax + Selank Composition
Semax (10mg)
Semax is studied for its effects on brain-derived neurotrophic factor and nerve growth factor expression, and in neuroprotection models of oxidative stress and ischaemia. Published work can be explored on PubMed.
Selank (10mg)
Selank is studied for its modulation of GABA-A receptor function, its effects in anxiety-related behavioural models and its influence on cytokine signalling as a tuftsin analogue.
Spray vs Lyophilised Vial
A lyophilised vial gives researchers full control over concentration and diluent, and is the better choice for most cell-culture work. The spray gives a metered, preserved solution with no reconstitution step, suited to delivery-model research where a consistent per-actuation dose matters. Many laboratories use both formats for different parts of a study.

Quality Control and Batch Testing
Every batch of the Semax + Selank spray is analysed before release. HPLC confirms purity, and mass spectrometry confirms that both peptides are present and correctly identified. You can view current certificates on our verification and testing page.
Storage and Handling
Store the spray refrigerated at 2–8°C, protected from light, and do not freeze. Once opened, use within 28 days and keep the nozzle clean between uses. For general guidance on solution stability, see how long reconstituted peptides last and our guide on how to store research peptides.
