TB-500 acts as a primary G-actin sequestering molecule in mammalian cells. By regulating actin polymerization, it facilitates rapid cell motility to sites of injury, promoting angiogenesis, dermal wound closure, and muscular tissue repair.
A synthetic version of the naturally occurring actin-sequestering protein Thymosin Beta-4, researched for cell migration and tissue regeneration.

TB-500 acts as a primary G-actin sequestering molecule in mammalian cells. By regulating actin polymerization, it facilitates rapid cell motility to sites of injury, promoting angiogenesis, dermal wound closure, and muscular tissue repair.
Binds monomeric actin to facilitate cytoskeletal remodeling, upregulates endothelial cell migration, and downregulates inflammatory cytokine cascades in damaged tissues.
Peer-reviewed publications, clinical trials, and preclinical research investigating TB-500.
Documented literature dosing intervals and published clinical trial protocols.
Biological delivery routes and standardized laboratory reconstitution principles.
Investigated via subcutaneous and intramuscular injection.
Lyophilized peptides must be reconstituted using sterile bacteriostatic water (0.9% benzyl alcohol) and maintained strictly refrigerated between 2°C - 8°C (36°F - 46°F), shielded from light.
