Recovery & Healing

TB-500 (Thymosin Beta-4 Acetate)

CAS #: 77591-33-4

TB-500 is a synthetic heptapeptide derived from thymosin beta-4, an endogenous protein essential for cell migration, tissue repair, and regeneration. It promotes healing by regulating actin for cell movement, stimulating angiogenesis, and reducing inflammation. Widely used for sports injuries, joint pain, and post-surgical recovery. Available as lyophilized powder with ≥99% purity.

Product Overview

TB-500 corresponds to the N-acetylated active fragment of thymosin beta-4, which plays a fundamental role in cell migration, survival, and tissue repair. TB-500 is specifically designed to harness the powerful regenerative capabilities of its parent molecule. It moves systemically through muscles, joints, and tissues, targeting areas in need of repair.

Mechanism of Action

TB-500 regulates actin polymerization, a protein essential for cellular structure and movement, enabling repair cells to migrate to injury sites. It promotes angiogenesis to ensure damaged tissues receive oxygen and nutrients, and reduces inflammation and oxidative stress to create a favorable healing environment.

Key Benefits

Wound Healing Acceleration — Stimulates endothelial cell migration and angiogenesis, re-establishing vascular networks to deliver oxygen and nutrients to damaged areas. Supports faster wound closure in skin, corneal injuries, and internal organ lesions.

Muscle Repair & Growth — Directly supports regeneration of muscle fibers, repairs torn or damaged tissue, reduces inflammation around injuries, and accelerates post-exercise recovery.

Anti-Inflammatory Properties — Modulates the body's inflammatory response, reducing swelling and discomfort from injuries and chronic conditions, enabling faster pain relief and improved mobility.

Tendon & Ligament Repair — Addresses the challenge of slow-healing connective tissues by promoting angiogenesis in poorly vascularized tendons and ligaments, enhancing collagen deposition and long-term structural integrity.
