How TB-500 works
Upregulates actin, a cell-building protein that plays a crucial role in cell movement and tissue repair. This helps cells migrate to damaged areas faster and promotes new blood vessel growth.
What research has looked at
- Enhanced wound healing
- Reduced inflammation
- Improved flexibility and reduced joint stiffness
- Hair regrowth potential
- Cardiac tissue repair support
Evidence level: Preclinical. Evidence comes from animal or lab studies; effects in people are not established. These are areas studied or reported, not promised effects.
