TB4 Thymosin Beta-4 is a naturally occurring 43-amino acid peptide that serves as the primary actin-sequestering protein in most mammalian cells. Preclinical research in animal and in vitro models investigates its involvement in cell migration, wound repair mechanisms, and tissue regeneration processes.
TB-500: This is a shorter, man-made chain of only 7 amino acids. It is made in a lab to be easier to produce while keeping the main healing power of TB4.
