TB4 (Thymosin Beta 4)
Investigational Thymosin Beta-4 peptide (regenerative / cytoprotective) · Pre-filled pen
TB4 is the naturally occurring peptide Thymosin Beta-4, a regulator of actin dynamics within cells. Preclinical work links it to cell migration, tissue remodelling, angiogenesis and the modulation of inflammation and fibrosis during healing. Human evidence is early-stage, so its role in recovery is studied rather than established.
Studied use areas
- Wound-healing signalling (research context)
- Tissue protection and regeneration
- Cell migration during repair
- Fibrosis and inflammation interface during healing
- Multi-tissue recovery frameworks
Safety & status
- Investigational and not an approved medicine; human safety data are early-stage and limited
- Prohibited in competitive sport under the WADA prohibited list
- Use only under qualified physician oversight with appropriate screening
