TB-500 (Thymosin Beta-4 Fragment Peptide)

TB-500 (Thymosin Beta-4 Fragment) is a synthetic active fragment of Thymosin Beta-4 (Tβ4). It consists of a 7-amino acid sequence Ac-LKKTETQ-OH with acetylation modification, corresponding to amino acids 17–23 of Tβ4. Retaining the actin-binding domain of the full-length peptide, it serves as the core fragment responsible for tissue repair.

As a synthetic fragment of naturally occurring human Thymosin Beta-4, TB-500 regulates the cytoskeletal protein actin to facilitate cell migration and wound healing, and promotes the migration of stem cells to damaged areas. In cardiology research, it has demonstrated protective and reparative effects on cardiomyocytes.

This product regulates actin, promotes cell migration and angiogenesis, and delivers anti-inflammatory and anti-fibrotic effects. It is applicable to sports injuries, joint inflammation, as well as the repair of various wounds and scars. It also helps improve myocardial and nerve damage and regulate general physical functions. Well tolerated by the body, it accelerates tissue healing and boosts recovery efficiency, serving as a widely used pharmaceutical-grade repair peptide.

Core Mechanisms
1.Actin regulation (primary mechanism)
lt binds and sequesters intracellular G-actin monomers, modulates actin polymerization kinetics, and facilitates cell migration, proliferation and tissue remodeling, laying a structural foundation for tissue repair.

2.Angiogenesis
It upregulates the VEGF pathway to stimulate neovascularization, improves oxygen and blood supply to poorly vascularized tissues such as tendons and ligaments, and accelerates recovery.
3.Anti-inflammation and anti-fibrosis
It inhibits the Akt signaling pathway, reduces the release of inflammatory factors, lessens scar tissue formation, and promotes functional repair rather than fibrosis.
4.Cell protection and regeneration
It suppresses cell apoptosis, boosts stem cell differentiation, enhances the migration of endothelial cells and keratinocytes, and speeds up the healing of skin, muscles and tendons.

Core Efficacy and Application Scenarios

1.Sports Injury Repair: Helps address tendinitis, ligament strains, muscle tears and articular cartilage damage, and shortens recovery time.

2.Chronic Pain and Inflammation: Relieves pain and swelling associated with arthritis, synovitis, tennis elbow and Achilles tendinitis.

3.Skin Repair and Anti-Aging: Promotes healing of wounds and burns, improves postoperative scars and acne scars, boosts collagen deposition and enhances skin elasticity.

4.Cardiovascular and Nerve Repair: Assists in repairing myocardial damage and improving microcirculation. Researches indicate it facilitates nerve regeneration.

5.Systemic Recovery: Repairs body tissues comprehensively, enhances athletic endurance and muscle recovery, and alleviates post-exercise soreness.
