About This Compound

TB-500 is a synthetic analogue of Thymosin Beta-4, a naturally occurring 43-amino-acid regenerative peptide. Its defining feature is the conserved actin-binding LKKTET motif, through which it binds G-actin to promote cell migration, endothelial tube formation and tissue regeneration throughout the body.

Unlike locally-acting repair peptides, TB-500 distributes systemically — making it well suited to whole-body recovery, connective-tissue flexibility, and vascular regeneration. In research models it has demonstrated accelerated wound closure, muscle and cardiac tissue repair, and resolution of inflammation.

TB-500 is commonly combined with BPC-157, which acts at the local injury site, to provide complementary local + systemic repair coverage.

Research & Mechanism Notes tap to view
Mechanism
Binds G-actin via the conserved LKKTET / SDKP motif, promoting cell migration, angiogenesis and stem-cell mobilisation system-wide.
Preclinical Evidence
Accelerated dermal wound healing, muscle and cardiac repair, and improved connective-tissue flexibility in rodent injury models.
Synergy
Systemic action complements BPC-157's local repair — the basis of the BPC-157 & TB-500 blend and the GLOW / KLOW stacks.
Storage Note
Lyophilised form stable at −20 °C for up to 24 months. After reconstitution, refrigerate and use within 28 days.
