    About TB-500 (Thymosin Beta-4)

    TB-500, also known as Thymosin Beta-4, is a potent peptide naturally found in the cells of almost all animals and humans. It plays a significant role in promoting tissue repair and accelerating wound healing, and is widely evaluated in the fields of sports rehabilitation, medicine, and scientific research. Extensive studies have shown that TB-500 is effective in repairing injuries such as tendon and ligament damage and bone fractures; its regenerative capabilities have also been validated in cardiac tissue repair. Favored by athletes for accelerating recovery and enhancing performance, it is also suitable for managing acute or chronic injuries, post-surgical rehabilitation, and recovery from various medical conditions. TB-500 offers a powerful solution for those seeking rapid repair, reduced inflammation, and improved overall tissue health.

    Key Advantages:
    Potent Tissue Repair: By regulating intracellular actin, TB-500 promotes cell migration and proliferation, accelerates wound healing and angiogenesis, and facilitates the regeneration of damaged fibers, thereby shortening recovery times.
    Significantly Faster Recovery: In both animal models and clinical trials, TB-500 has demonstrated the ability to significantly improve tissue damage conditions in a short period, helping patients and athletes recover quickly.
    Significant Anti-inflammatory Effects: Reduces local tissue inflammation, alleviates pain and swelling, and improves the tissue environment.
    Promotes Angiogenesis: Stimulates the formation of new blood vessels, enhances nutrient and oxygen supply to tissues, and accelerates the repair process.
    Versatile Applications: Beyond sports rehabilitation, it shows great potential in areas such as soft tissue injury repair, post-surgical recovery, cardiac tissue repair, and aesthetic medicine.
    Product Overview:
    This product is a high-quality TB-500 peptide, manufactured under strict quality control to ensure high potency and stability. It is designed to meet the needs of various sectors, including medicine, scientific research, sports rehabilitation, and aesthetics.

    ECHEMI Editorial Reference
    TB 500 is a synthetically made version of TB4 that facilitates healing and recovery by helping build new blood vessels, muscle tissue fibers, blood cells, and facilitating cell migration. It acts on the muscular system and has anabolic properties. TB 500 is used primarily for race animals (horses and dogs).

    Research
    Class:

    Actin-sequestering protein / 43-amino-acid peptide

    Status:

    Research compound — Not FDA approved (investigational: RGN-259 for dry eye / neurotrophic keratitis)

    Mechanism:

    A naturally occurring 43-amino-acid peptide (Ac-Ser-Asp-Lys-Pro-Asp-Met-Ala-Glu-Ile-Glu-Lys-Phe-Asp-Lys-Ser-Lys-Leu-Lys-Lys-Thr-Glu-Thr-Gln-Glu-Lys-Asn-Pro-Leu-Pro-Ser-Lys-Glu-Thr-Ile-Glu-Gln-Glu-Lys-Gln-Ala-Gly-Glu-Ser-OH) that binds G-actin (sequesters monomeric actin), preventing F-actin polymerization. Promotes cell migration, angiogenesis, wound healing, and anti-inflammatory responses via integrin-linked kinase (ILK) and HIF-1α/VEGF pathways. TB-500 is the synthetic fragment Ac-LKKTETQ (MW ~895) often sold under this CAS.

    Activity note:

    Thymosin Beta-4 is an actin-binding protein, not a receptor agonist. Functional activity is measured by actin sequestration (Kd ~0.7–1 μM) and cell migration assays, not EC₅₀.
