About Thymosin Beta-4
It is found in high concentrations in blood platelets, wound fluid and other tissues in the body.
Tβ4 is not a growth factor; rather, it is a major actin regulating peptide.
Thymosin Beta 4 is a synthetic version of the naturally occurring peptide present in virtually all human and animal cells, Thymosin Beta 4 (Tß4).
TB-500 (Thymosin Beta-4) is a synthetic peptide that mirrors the naturally occurring thymic peptide found in almost all human and animal cells.
