How does it work?
TB-500 is a synthetic fragment of thymosin beta-4, a protein the body uses in wound healing. Thymosin beta-4 binds actin, a building block cells need to move, which in lab and animal studies helps cells reach injured tissue. Evidence comes mostly from animal studies.
What does the research say?
