THE FULL-SPECTRUM HEALER
TB4, Tβ4, Thymosin β-4
Thymosin Beta-4 is a 43-amino-acid peptide that your body naturally produces to orchestrate healing. It promotes blood vessel formation, reduces scarring (fibrosis), and protects tissues from damage. It's particularly valued for heart recovery after injury and reducing inflammation throughout the body. TB-500 is a fragment of this full-length peptide.
