What is TB-500?
TB-500 is a synthetic peptide derived from thymosin beta-4 (TB4), comprising a 43-amino-acid sequence that mimics the active region of TB4. It binds actin and regulates cytoskeletal dynamics to facilitate cell migration and tissue repair.
When you buy TB-500 from Mega Protide, you’re getting a research-grade peptide that has been third-party tested for purity and potency. This TB-500 research peptide is widely used in tissue repair, angiogenesis, and wound healing research.

Mechanism of Action of TB-500
TB-500 exerts its effects through actin binding and cytoskeletal modulation:
| Mechanism | Effect |
|---|---|
| Actin Polymerization | Sequesters G-actin and promotes F-actin polymerization, enhancing cell motility by 20-30% |
| Angiogenesis Promotion | Upregulates VEGF expression by 15-25%, stimulating new blood vessel formation |
| Anti-Inflammatory Effects | Reduces TNF-α and IL-6 by 20-25%, mitigating inflammation and tissue damage |
| Cell Migration | Facilitates fibroblast and endothelial cell migration to injury sites |
| Extracellular Matrix Remodeling | Increases collagen and fibronectin deposition by 15-20% |
| Tissue Regeneration | Promotes repair of skin, muscle, and connective tissue |
Key Advantage: TB-500 is a synthetic fragment of thymosin beta-4 with a long half-life (48-72 hours), allowing for flexible dosing schedules in research protocols.
