TB 500 is a synthetic fraction of the protein thymosin beta-4, which is present in almost all human and animal cells. The main purpose of this peptide is to promote healing. It also promotes the production of new blood and muscle cells. The curative effects of TB 500 have been observed in tendons, ligaments, muscles, skin, heart and eyes.
Thymosin beta-4 is naturally produced in higher concentrations where tissue is damaged. This peptide is also a very powerful anti-inflammatory agent.
TB 500 differs from other repair factors (growth hormone, IGF-1) in that it promotes endothelial and keratinocyte migration. It also does not bind to the extracellular matrix and has a very low molecular weight. This allows it to travel long distances through the tissues in the human body.
One of the main mechanisms of action of TB 500 is its ability to regulate the cell-building protein actin. Of the thousands of proteins present in human cells, actin represents about 10% of the total. So it is an essential part of cell structure and movement.
