Thymosin Beta-4 is a 43 amino acid peptide sequence. In animal models, Thymosin Beta-4 has been shown to improve blood vessel growth, regulate wound healing, decrease inflammation, and reduce oxidative damage in the heart and central nervous system. Thymosin-beta-4 has a role in protection, tissue repair, regeneration and remodeling of injured or damaged tissues. It is also of active interest in anti-aging research.
