TB-500, also known as Thymosin Beta-4, is a synthetic peptide composed of 43 amino acids. In animal studies, Thymosin Beta-4 has demonstrated a range of therapeutic effects, including promoting blood vessel formation, accelerating wound healing, reducing inflammation, and limiting oxidative damage in both the heart and central nervous system. It plays a key role in tissue protection, repair, regeneration, and remodeling following injury. Due to these properties, Thymosin Beta-4 is also being actively explored in the field of anti-aging research.
