Scientific Background

Looking to support faster recovery and tissue renewal? This powerful synthetic fragment offers promising benefits for those exploring advanced healing protocols. Whether addressing injury repair or overall resilience, it can make a real difference in your progress.

TB-500 is a lab-created version of a key active portion of thymosin beta-4, a naturally occurring protein that plays a central role in cell structure, movement, and repair processes. It supports tissue regeneration by influencing actin dynamics and promoting blood vessel formation.

This compound mirrors the biologically active region of thymosin beta-4, focusing on actin binding to drive cell migration, new vessel growth, and reduced scarring. Preclinical work shows it helps lower cell death, ease swelling, and accelerate wound closure while supporting stem cell activity.

Intended Research Use

Accelerates wound closure and tissue rebuilding
Promotes new blood vessel development for better nutrient delivery
Reduces inflammation and scar tissue formation
Supports cell movement and differentiation
Aids neurological and cardiovascular recovery pathways
Enhances hair follicle activity in certain models
Boosts antibiotic effectiveness in infection studies
