How it works, simply
It interacts with actin, a structural protein involved in cell movement.
What the evidence tells us
Research on full-length thymosin beta-4 cannot be assigned automatically to products labeled TB-500.
No study-by-study evidence summary has been verified for this profile yet. The explanation above describes its purpose and limits, not a proven benefit for every use.
