    Mechanism of Action (Core: Modulation of Neurotransmitters and Neurotrophic Factors)

    Unlike traditional anti-anxiety medications that directly activate GABA receptors, Selank exerts its effects by modulating multiple neurotransmitter systems and neurotrophic pathways.

    1. Modulation of the GABAergic System

    Selank may enhance:

    ·GABA (Gamma-Aminobutyric Acid) neurotransmission
    ·Inhibitory neural signaling

    Potential results:

    ·Reduced anxiety
    ·Relief of tension and nervousness
    ·Decreased stress response

    Compared with benzodiazepines, studies suggest that Selank produces milder sedative effects and is less likely to cause significant drowsiness.

    2. Regulation of Monoamine Neurotransmitters

    Research indicates that Selank may influence:

    ·Serotonin
    ·Dopamine

    Through these effects, Selank may contribute to:

    ·Emotional stability
    ·Motivation regulation
    ·Maintenance of cognitive function
    3. Promotion of BDNF Expression

    Selank may increase the levels of:

    ·BDNF (Brain-Derived Neurotrophic Factor)
    ·NGF (Nerve Growth Factor)

    Potential benefits include:

    ·Neuroprotection
    ·Enhanced neuroplasticity
    ·Support for learning and memory processes
    4. Immunomodulatory Effects

    As a derivative of Tuftsin, Selank also exhibits immunomodulatory properties, including:

    ·Regulation of immune function
    ·Modulation of inflammatory cytokines
    ·Maintenance of immune balance during stress conditions

    Q: How do i keep the peptides when i receive it ?

    A: Peptides in the form of lyophilized powder can be transported at room temperature by vacuum packaging, while polypeptides in the dissolved state need to be refrigerated at 2°C - 8°C. For long-term storage, peptides should be stored in the form of lyophilized powder store at -20°C or -80°C in a sealed container with desiccant, which can avoid the degradation of peptides to the greatest extent.
