What is TB-500?
TB-500 is a synthetic analogue of Thymosin Beta-4, a naturally occurring peptide found in high concentrations in blood platelets, wound fluid, and various tissues throughout the body. It plays a central role in the body's natural healing and recovery processes, making it one of the most researched peptides for injury repair and performance recovery.
Mechanism of Action
TB-500 works primarily by upregulating actin — a protein essential for cell structure and movement. By promoting actin polymerisation, TB-500 facilitates cell migration to injury sites, accelerating tissue repair. It also promotes angiogenesis, reduces inflammation, and supports the differentiation of stem cells into specialised repair cells. Its low molecular weight and flexible structure allow it to travel systemically, making it effective even when administered away from the injury site.
Key Research Applications
- Muscle Repair: Demonstrated acceleration of skeletal muscle regeneration following injury, with reduced fibrosis and improved functional recovery.
- Tendon & Ligament Healing: Studies show improved collagen deposition and tensile strength in damaged connective tissue.
- Cardiac Repair: Preclinical research indicates TB-500 may support cardiomyocyte survival and regeneration following ischaemic injury.
- Anti-Inflammatory: Exhibits potent anti-inflammatory properties, reducing cytokine activity at injury sites.
- Hair Growth: Emerging research suggests potential for stimulating hair follicle stem cells.
