TB-500 is used for the purpose of research. It is known to mimic part of the larger peptide known and Thymosin Beta 4. However, because TB-500 has a much smaller molecular weight it is easier to use than the full Thymosin Beta 4 peptide. This synthetic peptide has a long list of benefits and no known side effects which makes it the ideal peptide for those seeking muscle gain and a quick healing time. TB-500 works by building new blood vessels and muscle tissue fiber while assisting in new cell migration and blood cell reproduction. It works based on its ability to upregulate cell building proteins such as actin. In both powder form and in reconstituted form, TB-500 should be stored between thirty-six- and forty-six-degrees Fahrenheit for optimal use.
