TB-500
TB-500
TB-500 is the synthetic form of the active region of Thymosin Beta-4, a naturally occurring 43-amino-acid protein present in nearly all human cells and first identified in the thymus. As the body's primary actin-sequestering peptide, it regulates the cytoskeletal dynamics essential to cell migration, proliferation, and differentiation. Research shows TB-500 upregulates actin, promotes angiogenesis, and recruits endothelial and stem cells to sites of injury, accelerating wound closure and tissue remodeling. Studies demonstrate enhanced healing of muscle, tendon, ligament, skin, and corneal tissue, along with cardiac repair through new blood-vessel formation and reduced fibrosis. The peptide also exhibits anti-inflammatory activity and upregulates genes tied to cell survival. Its exceptional mobility through tissue, owing to a low molecular weight and flexible structure, allows systemic distribution to distant injury sites. These characteristics make TB-500 a key model compound in regenerative, cardiovascular, and wound-healing research.

Frequently Asked Questions
Are your products third-party tested?
Yes. Every batch is independently tested for identity and purity by HPLC and mass spectrometry at U.S. accredited labs, and a Certificate of Analysis is available for each batch.
What purity can I expect?
All compounds are 99%+ purity, verified by HPLC.
How should this be stored?
Store lyophilized (freeze-dried) material cool and dry; refrigerate once reconstituted. Refer to the product details for compound-specific guidance.
How fast do you ship?
Orders generally ship within 1–2 business days in temperature-controlled, tamper-evident packaging with tracking.
Are these safe for human use?
No. All products are sold strictly for in-vitro research and laboratory use only and are not for human or animal consumption.
