What is the difference between TB-500 and Thymosin Beta-4?
TB-500 is a synthetic fragment of the naturally occurring protein Thymosin Beta-4. It contains the active region responsible for healing properties but is shorter and more practical to manufacture. They share the same mechanism of action, though full-length Thymosin Beta-4 may have additional biological activities.
