TB4-Frag
Thymosin Beta-4 Fragment (Active Fragment)
The short, bioactive core of the Thymosin Beta-4 molecule, specifically the 17-23 amino acid segment believed to drive many of TB-500's healing and anti-fibrotic effects. A more targeted alternative to the full TB-500 chain.
Growing evidence. Some early human studies
Tissue Repair
Studied as the core active sequence responsible for Thymosin Beta-4's anti-inflammatory and tissue healing properties, with research suggesting equivalent or superior efficacy in some models.
Anti-Fibrotic Support
Studied for reducing the formation of scar tissue and fibrosis following injuries, potentially preserving tissue quality better than full-chain TB-500.
Neuroprotection
Published research suggests this specific fragment has independent neuroprotective properties, separate from the full Thymosin Beta-4 molecule, with potential applications in brain and nerve injury recovery.
