99% Peptides Selank peptide CAS NO. 129954-34-3 with Stable Global Supply for Research Use

Selank is a synthetic peptide derived from the naturally occurring peptide tuftsin, which is associated with immune function. It is primarily recognized for its anxiolytic (anxiety-reducing) and nootropic (cognitive-enhancing) properties. Developed in Russia, Selank has been studied for its potential benefits in treating anxiety disorders, enhancing memory and learning, and improving overall cognitive function.

Mechanism of Action

Selank's mechanism involves several key actions:
GABA Modulation: Selank is thought to modulate the GABAergic system, enhancing the effects of GABA (gamma-aminobutyric acid), a major inhibitory neurotransmitter in the brain. This modulation may help reduce anxiety and promote relaxation without the sedative effects commonly associated with traditional anxiolytics.
Neurotransmitter Regulation: It influences levels of serotonin, noradrenaline, and dopamine, which are critical for mood regulation and cognitive functions. Increased serotonin levels can improve mood and appetite while reducing anxiety.
Brain-Derived Neurotrophic Factor (BDNF) Enhancement: Selank has been shown to increase BDNF levels, which are essential for neuroplasticity, learning, and memory. This effect may contribute to its cognitive-enhancing properties.

Applications

Selank is indicated for:
Generalized Anxiety Disorder (GAD): Clinical trials suggest it can effectively reduce anxiety symptoms without the sedative effects or addiction risks associated with benzodiazepines.
Cognitive Enhancement: It may improve memory, learning abilities, and overall cognitive function.
Stress Reduction: Selank can help manage stress responses and improve resilience to stressors.
Immune Function Support: By modulating immune responses, it may enhance the body's ability to fight infections.

Routes of Administration

Selank is primarily administered via:
Intranasal Spray: This method allows for effective delivery directly into the bloodstream and brain.
Subcutaneous Injection: An alternative route that may be used in certain clinical settings.

Safety and Side Effects

Common Side Effects
While Selank is generally considered safe, some users report mild side effects, including:
Nasal irritation or discomfort (when administered as a nasal spray)
Headaches
Fatigue
Dizziness
Mild gastrointestinal discomfort
Serious Side Effects
Serious adverse effects are rare but can include:
Allergic reactions (e.g., rash, swelling)
Changes in blood pressure or heart rate
Severe headaches or visual disturbances
Precautions
Caution should be exercised in individuals with allergies to peptides or those with pre-existing health conditions. It's advisable to consult healthcare professionals before starting Selank therapy.

Pharmacokinetics

Absorption and Distribution
Selank is rapidly absorbed through the nasal mucosa when administered as a spray. Its pharmacokinetic profile indicates quick onset of action due to direct absorption into systemic circulation.
Metabolism and Excretion
As a peptide, Selank is likely metabolized by proteolytic enzymes in the body. Detailed studies on its metabolic pathways are limited.
