TB-500 is a synthetic version of the 43-amino-acid peptide Thymosin Beta-4, a naturally occurring protein found in virtually all human and animal cells. It is studied for its role in cell migration, actin regulation, and tissue remodelling. Research publications have explored its potential in musculoskeletal and cardiovascular models. NewChem's TB-500 is independently verified at ≥99% HPLC purity with endotoxin testing on every batch.
Add 2 mL bacteriostatic water to the 10 mg vial to yield 5,000 mcg/mL. TB-500 dissolves readily — gentle swirl, do not shake.
