TB 500 10mg
TB 500 is the synthetic version of Thymosin Beta-4 (Tβ4), a naturally occurring 43-amino-acid peptide present in virtually all human and animal cells. Each vial contains 10mg of lyophilized, high-purity TB 500, making it a popular choice among researchers studying tissue repair, inflammation, and cellular regeneration.
 
What Is TB 500?
Thymosin Beta-4 is one of the most abundant and versatile peptides in the body, playing a central role in the polymerization of actin — a protein critical for cell structure, movement, and repair. TB 500 mirrors the active region of Tβ4 and has been extensively studied in preclinical models for its potential role in wound healing, muscle recovery, and angiogenesis. Its low molecular weight and flexibility allow it to travel long distances through tissue, making it a uniquely systemic research compound.
