    The Importance of Peptides:

    Many active substances in the human body exist in peptide form. Peptides participate in hormonal, neural, cellular growth and reproductive processes, regulating the physiological functions of various systems and cells. They activate relevant enzyme systems, promote the permeability of intermediate metabolic membranes, influence DNA transcription, or affect specific protein synthesis, ultimately producing specific physiological effects. As key participants in numerous cellular functions, peptides can be synthesized by cells and regulate their functional activities. They also act as neurotransmitters to transmit information and serve as transport carriers, delivering nutrients, vitamins, biotin, calcium and beneficial trace elements to the cells, organs and tissues of the body. As important physiological regulators, peptides comprehensively modulate physiological functions, enhance physiological activity, and play significant biological roles.

    Product Benefits



    I. Core Efficacy

    • Anxiolytic: Selank effectively regulates the brain's neurotransmitter system by acting on gamma-aminobutyric acid (GABA) receptors. It promotes the neurotransmission function of GABA, inhibits excessive excitation of the nervous system, and thus alleviates anxiety. Clinical studies have shown that Selank can significantly relieve symptoms in patients with generalized anxiety disorder. Moreover, unlike traditional anxiolytic drugs, it does not cause common side effects such as drowsiness or addiction, thereby improving the quality of life of patients.

    • Cognitive Enhancement: It has a positive impact on brain regions related to learning and memory. Selank the expression of brain-derived neurotrophic factor (BDNF), promotes the growth, survival, and differentiation of neurons, and enhances synaptic plasticity. This helps users improve memory, attention, and learning ability, making it beneficial for students facing academic challenges and professionals aiming to boost work efficiency.

    • Immune Regulation: As an analog of tuftsin, Selank participates in the regulation of the human immune system. It enhances the activity of immune cells, for example, by promoting the phagocytic function of macrophages. It also regulates the secretion of inflammatory factors, improving the body's resistance to pathogens and helping the body defend against various diseases.

    II. Mechanism of Action

    In the nervous system, Selank inhibits the activity of enkephalinase in the brain, reducing the degradation of enkephalin and increasing its levels. It binds to opioid receptors in the body, producing anxiolytic and pain-relieving effects. At the same time, it regulates the release and metabolism of neurotransmitters such as serotonin and dopamine, stabilizing mood, enhancing motivation, and improving cognition. In the immune system, Selank regulates the signaling pathways of immune cells, enabling immune cells to better recognize and eliminate pathogens and maintaining immune balance in the body.

    Ⅲ. Safety and Precautions

    Selank has good safety characteristics. It is free from embryotoxicity, teratogenicity, allergenicity, and irritation, and does not cause drug dependence. However, pregnant women, breastfeeding women, and individuals under 18 years of age are not recommended to use it due to the lack of relevant safety and efficacy research data. People who are taking other medications, especially psychiatric drugs or drugs with central nervous system effects, must consult a doctor before using Selank to avoid drug interactions.

    Product Usage


    Metabolic Research Applications

    In addition to its involvement in glucose-related metabolic pathways, tirzepatide has been widely studied in areas such as appetite signaling, dietary intake, energy homeostasis, and body weight regulation. Its activity across two receptor pathways provides a broader approach for metabolic research.

    Appetite and Satiety

    Tirzepatide is studied for its interaction with signaling pathways associated with hunger and satiety. Research suggests that these pathways may influence appetite, feelings of fullness, and overall food intake.

    Dual-Receptor Activity

    Through simultaneous activity at GIP and GLP-1 receptors, tirzepatide enables researchers to explore metabolic regulation through two complementary pathways rather than a single-receptor mechanism.

    Energy and Lipid Metabolism

    Tirzepatide is also investigated in studies involving adipose tissue, energy utilization, lipid metabolism, and body composition, providing additional research perspectives on metabolic balance and fat distribution.

    Integrated Metabolic Regulation

    The combined activity of GIP and GLP-1 pathways may contribute to coordinated metabolic responses and overall metabolic homeostasis. Experimental results can vary depending on study design, models, dosage, and other research conditions.

    ECHEMI Editorial Reference
    Selank is a synthetic derivative of the tetrapeptide tuftsin that contains a proline-glycine-proline sequence at the C-terminus and has anxiolytic and anti-inflammatory activities. It increases the amplitude and discharge rate of inhibitory postsynaptic currents of neurons in the rat hippocampal CA1 region when used at a concentration of 1 μM. It decreases the level of affective responses and the number of erroneous escape attempts in rats in an acute stress situation, increases orientational-investigative responses of rats in an unfamiliar situation, and reduces the time mice spend immobile in the forced swim test. It increases locomotor activity of high-anxiety Balb/c, but not C57Bl/6, mice in the open field test. Selank (0.01 mg/kg) decreases verticalization induced by apomorphine in mice. It also decreases expression of the inflammation-related genesIl2rgandXcr1in mouse spleen after 90 minutes when administered at a dose of 100 μg/kg.
    SELANK Synthetic is a single, non-glycosylated polypeptide chain containing 7 amino acids, having a molecular mass of 751.89  Dalton and a Molecular formula of C33H57N11O9.
