Is TB-500 the same as thymosin beta-4?
No, though the names are swapped almost everywhere the product is sold. Thymosin beta-4 is the full 43 amino acid protein, about 4,963 daltons in weight. It has been through early, mid-stage, and late-stage studies in people. TB-500 is a lab-made 7 amino acid piece of it, about 889 to 949 daltons depending on the salt form, with no published study in people at all. A 2012 lab test at Ghent University confirmed that products sold as TB-500 really did contain this shorter piece.
