Scientific background
Independent researchTB-500 (thymosin β4 fragment)
TB-500 is marketed as a synthetic version or fragment of thymosin β4 (Tβ4), a naturally occurring protein involved in cell migration and tissue repair1.
Research evidence
Independent researchTB-500 (thymosin β4 fragment)
Thymosin β4 accelerated dermal healing in animal models and in phase 2 trials in patients with pressure ulcers, venous stasis ulcers and epidermolysis bullosa wounds1. Those trials used the full natural protein in clinical settings, not TB-500 products.
