TB-500 (Thymosin Beta-4 Fragment): Research Overview
What TB-500 is, how it relates to thymosin beta-4, and what to look for when sourcing it for research.
What it is
TB-500 is a synthetic peptide related to thymosin beta-4, a naturally occurring protein involved in cell migration and regulation. It is studied in preclinical settings for its role in these cellular processes.
As with all compounds we cover, TB-500 is sold for research use only.
Sourcing considerations
TB-500 is frequently paired with BPC-157 in research blends. Whether buying it alone or in a stack, confirm purity and identity through a batch COA. Suppliers that publish these documents publicly rank higher in our reviews.
