Selank is investigated in preclinical models for anxiolysis, cognitive modulation, and stress-response stabilization without sedative effects. Applications include laboratory evaluation of allosteric GABA-A receptor signaling, monoamine neurotransmitter turnover (specifically serotonin and dopamine), enkephalinase inhibition, and neurotrophic factor expression including BDNF and NGF.

Persistent stress, mental chatter, and social tension frequently drain cognitive energy and undermine daily focus. While conventional anxiolytics often result in daytime sedation, sluggishness, or dependency risks, Selank Nasal Spray provides calm composure without blunting mental sharpness. By delivering active tuftsin-derived heptapeptides straight across the nasal mucosa, Selank balances central neurotransmission, preserves endogenous enkephalins, and stabilizes emotional resilience under cognitive strain.

Key Highlights of Selank Nasal Spray

  • Allosteric GABA-A Modulation: Modulates central inhibitory GABA-A receptor signaling to reduce mental tension and anxiety without daytime grogginess.
  • Enkephalin Degradation Defense: Inhibits the enzymes that break down endogenous enkephalins, helping sustain a balanced mood and neurochemical equilibrium under pressure.
  • Needle-Free Nasal Delivery: Liquid spray formulation engineered for direct mucosal absorption, bypassing gastrointestinal digestion and hepatic first-pass metabolism.
  • Supports Neurotrophic Signaling: Stimulates expression of Brain-Derived Neurotrophic Factor (BDNF) and Nerve Growth Factor (NGF) to maintain memory retention and executive clarity.

Shipped Unmixed — And Why That Matters

Standard Labs does not ship pre-diluted peptide nasal sprays. Peptides in liquid solution are substantially less stable than in dry form; when dissolved in water, molecular bonds gradually break down over time through hydrolysis. A pre-mixed bottle begins degrading the day it is filled and continues to lose potency during transit, temperature fluctuations, and warehouse storage.

To guarantee maximum molecular integrity, our kit is shipped unmixed:

  • Unmixed Freeze-Dried Peptide: Pure, lyophilized peptide powder sealed in a vacuum-tight glass vial to preserve biological stability and prevent degradation during transit.
  • Dedicated Nasal Saline Solution: Pre-measured sterile nasal saline formulated specifically for gentle, non-irritating mucosal absorption—no need to purchase separate reconstitution water.
  • Precision Spray Atomizer: A specialized metered nasal actuator engineered to deliver an ultra-fine aerosol mist evenly across the nasal mucosa.
  • Controlled Freshness Window: Because you dissolve the powder into the nasal saline only when you are ready to begin, you maintain a fresh, known in-use window rather than guessing how long a pre-mixed solution sat in transit.

What’s Included in the Kit

  • 1x Vial Lyophilized Peptide (Freeze-dried research powder)
  • 1x Bottle Sterile Nasal Saline Solution (Formulated diluent for nasal delivery)
  • 1x Metered Nasal Spray Atomizer (Precision calibrated pump bottle)
