What TB-500 is

TB-500 is a synthetic peptide corresponding to the actin-binding region of thymosin beta-4, an endogenous protein involved in cytoskeletal dynamics. In research catalogues it is the shorter, more practical fragment used when a lab wants a defined actin-sequestering ligand rather than the full parent protein.

It is routinely discussed alongside BPC-157 because the two are studied for complementary steps in wound and connective-tissue models: TB-500 for cell locomotion, BPC-157 for vascular and fibroblast signalling. That pairing is why we stock them together.

Mechanism in published models

TB-500 binds G-actin monomers and shifts the polymerisation equilibrium that lets endothelial cells and keratinocytes move. Papers in this area talk about directed migration to an injury site, VEGF upregulation, and matrix remodelling — systemic, whole-tissue language rather than a single local injection story.

That systemic character is the practical distinction from BPC-157 in the literature. One is more often framed as local repair signalling; TB-500 is framed as cytoskeletal and migratory. Neither frame is a licence to use the material in people.

TB-500 is not TGA-approved for human use and sits on the WADA prohibited list. 10KITSM lists it only as a laboratory reference material.

How 10KITSM supplies TB-500

We do not offer a TB-500-only vial. The 10mg of TB-500 in the catalogue is co-lyophilised with 10mg of BPC-157. If a protocol calls for the pair, that is the SKU. If a protocol calls for TB-500 alone, this site is not the source for a single-compound vial.

Purity is third-party HPLC tested at 99%+. Shipping is discreet express within Australia. Handling notes are in the user guide, written against published research protocols, not as directions for self-administration.

Frequently asked questions

Do you sell TB-500 on its own?

No. TB-500 is supplied as 10mg inside the 20mg BPC-157 + TB-500 blend. There is no standalone TB-500 SKU.

Is TB-500 the same as thymosin beta-4?

TB-500 is a synthetic fragment of thymosin beta-4, corresponding to its actin-binding region. It is not the full parent protein.

Is TB-500 for human use?

No. It is for laboratory research only, not for human or veterinary use, and not for consumption.
