What Is TB-500?
TB-500 is a synthetic analog of Thymosin Beta-4, a naturally occurring 43-amino acid peptide present in high concentrations in blood platelets, wound fluid, and various tissues. The active fragment (Ac-LKKTETQ) retains the key biological activity of the full-length peptide.
Research into TB-500 focuses on its role in actin regulation and cell migration. Studies have examined its effects on angiogenesis through upregulation of vascular endothelial growth factor (VEGF), extracellular matrix remodeling, inflammation resolution, and stem cell differentiation.
TB-500 is frequently studied alongside BPC-157 due to their complementary mechanisms. Pure Pharm Peptides also offers a BPC-TB500 Blend for researchers studying both compounds simultaneously.
All TB-500 products are sold strictly for in vitro research and laboratory use. Not approved by the FDA for human or animal consumption.
