TB500 peptide, also written TB-500, is a synthetic peptide modelled on the active region of thymosin beta-4, a protein found in almost every animal cell. Vi Corpus supplies it as a 5 mg lyophilised vial for Australian laboratories studying cell migration, actin dynamics and wound models.
Key research features of TB500 peptide
- Actin-binding focus. Thymosin beta-4 regulates G-actin, so TB-500 is widely used to study how cells move and remodel.
- Wound and tissue models. Preclinical papers cover dermal wounds, cardiac tissue and corneal injury.
- Small, mobile molecule. Its size lets researchers study effects beyond the local site.
- Wolverine stack partner. It is commonly paired with BPC-157 in combined recovery research.
- Third-party tested. Batch results can be requested through our Lab Tests page.

Research applications
Thymosin beta-4 has been studied for decades. For instance, researchers have examined its role in endothelial cell migration, new blood vessel formation and the reduction of inflammatory signalling after injury. Animal work has also looked at heart muscle repair after induced infarction. Because TB-500 reproduces the protein’s actin-binding sequence, it gives labs a cost-effective tool for these questions. Even so, it is not approved for human use, and our supply is limited to research settings.
Why labs choose Vi Corpus TB500 peptide
Our vials ship from Australia, so there are no international customs delays. In addition, orders placed before 12pm AEDT on weekdays leave the same day. Each batch is third-party tested, and you can explore matching compounds in our recovery and regenerative peptides range.
Frequently asked questions
Is TB-500 the same as thymosin beta-4?
Not exactly. Thymosin beta-4 is a 43-amino-acid protein, while TB-500 is a synthetic peptide based on its active actin-binding region.
What is the wolverine peptide stack?
It is the research pairing of TB-500 with BPC-157. Many labs study the two together because they act through different pathways.
How should TB-500 be stored?
Keep unopened vials refrigerated. After mixing with bacteriostatic water, store the solution at 2–8 °C.
