TB-500
Research Peptide | Lyophilized Powder | Batch Tested
For laboratory research use only. Not for human or animal consumption. Insulated shipping · Styrofoam box available.
Product Overview
TB-500 is a synthetic peptide corresponding to the active region of Thymosin Beta-4, a naturally occurring protein that is one of the primary regulators of the cytoskeletal protein actin. Because actin dynamics underlie cell migration, wound closure and blood-vessel growth, TB-500 is a central tool compound in tissue-repair and regeneration research.

SKU & packaging
Nominal sizes describe the product label; measured results are listed in each batch report. Published reports do not confirm the batch allocated to a future order.
Product & documentation questions
How do I read the size and pack quantity?
The per-vial size and number of vials per pack are listed separately in the table. The displayed price is for one pack. A blend’s stated size can describe combined ingredients; check its product label and report for individual components.
How do I find the matching COA?
Match the product, SKU and batch number with the published report. Open the batch page to read the actual results, original report and laboratory verification link. Ask support to confirm the allocated batch if it is not on your order.
Does a purity result mean every test passed?
No. Identity, purity, fill and endotoxin are separate measurements. Read each reported result and unit. An absent result is not a pass, and a less-than result is not zero.
Research Information
TB-500 is studied for its regulation of actin polymerization, cell migration, angiogenesis and the recruitment of repair cells to injured tissue in wound-healing and regeneration models. It is frequently examined alongside BPC-157, where researchers study whether the two peptides act through complementary repair mechanisms. Supplied strictly for in-vitro and laboratory research use only — not for human or animal consumption.
