Thymosin Beta-4
Healing & RegenerationThymosin Beta-4 is an endogenous peptide critical for cellular repair and cytoskeletal regulation. It plays a key role in tissue regeneration, inflammation control, and angiogenesis. Distinct from synthetic TB-500 fragments, full-length TB4 is being studied for cardiac recovery, neurological healing, and advanced wound care.
