About Selank Nasal Spray
This supplies Selank — the tuftsin analogue with a Pro-Gly-Pro tail — in solution in a metered 20ml intranasal bottle.
As with Semax, much of the primary research on this compound used the intranasal route, so the presentation aligns a study with the published method rather than departing from it.
What the research covers
Research context is unchanged from the vial: GABAergic and serotonergic signalling, anxiolytic endpoints without the sedation profile of classical GABA-A agents, and the immunomodulatory strand that follows from its tuftsin origin.
Concentration is fixed, which suits repeated-session consistency and does not suit dose-ranging. Semax versus Selank sets out why the two are complementary rather than interchangeable. The cognitive and sleep research peptides hub covers this group.
Handling Selank Nasal Spray
Supplied as a metered preparation, so there is no reconstitution step and no reconstitution error — and no opportunity to set the concentration, which is fixed at what is supplied.
Store cold, upright and away from light. A peptide already in aqueous solution has a shorter usable life than a sealed lyophilised vial; this format trades shelf stability for immediate usability and for consistency between sessions.
Other formats
The same compound is supplied as a lyophilised Selank vial, which gives control over concentration that a fixed solution cannot.
Common questions about Selank Nasal Spray
Is this the same compound as the Selank vial?
Yes. The compound is identical; it is supplied already in solution in a metered intranasal bottle instead of as a lyophilised powder.
When is the nasal spray the better choice?
When the intranasal route is itself part of the study design, or when consistency between sessions matters more than control over concentration.
When is the vial the better choice?
When the protocol needs to set its own concentration or run dose-ranging. A fixed-concentration solution cannot be varied.
How long does the spray remain usable?
A peptide in solution has a shorter usable life than a sealed lyophilised vial. Keep the bottle cold, upright and protected from light, and treat its life as limited.
