INTRODUCTION

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.

What is this used for?

Tissue Repair

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

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

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.

How do you take it?
