TB-500: Research Profile, Dosages & Supplier Prices
TB-500 is a repair / recovery research compound with a molecular weight of ~889 g/mol (fragment) and a research half-life of longer-acting than parent thymosin beta-4 in preclinical models due to fragment design. TB-500 is a synthetic research peptide based on the active region of Thymosin Beta-4, a naturally occurring 43-amino-acid protein involved in actin regulation and cell migration. The fragment design was developed to retain the regions most studied for tissue repair while improving stability and synthesis economics.

What is TB-500?
Preclinical research has investigated TB-500 in models of cardiac repair, dermal wound healing, corneal injury, and musculoskeletal damage, with a focus on cell migration, angiogenesis, and inflammation modulation.
TB-500 is frequently stacked with BPC-157 in research settings (the combination is often marketed as the Wolverine blend). When comparing suppliers, verify that the COA matches the fragment sequence actually being sold, as some vendors substitute full thymosin beta-4 or unrelated peptides.
Mechanism of Action (Research Context)
Studied for actin sequestration regulation, promotion of cell migration and differentiation, angiogenesis support, and reduction of inflammatory markers in animal injury models.
Research Areas
TB-500 Dosages in Research
