TB-500 (a synthetic thymosin beta-4 fragment) is supplied by Onyx Peptides as a high-purity research material for laboratory use, with tracked, discreet UK dispatch.
What is TB-500?
TB-500 is a synthetic peptide modelled on the active region of thymosin beta-4, a naturally occurring protein that binds actin, one of the main building blocks of a cell's internal skeleton.
How TB-500 is studied
Thymosin beta-4 has been studied in cell and animal models of cell migration, wound healing and tissue repair. Thymosin beta-4 and its fragments appear on the World Anti-Doping Agency prohibited list.
- Cell migration and actin regulation
- Wound-healing models
- Tissue-repair research, often alongside BPC-157
TB-500 from Onyx Peptides
We supply TB-500 in 5 mg and 10 mg vials, and combined with BPC-157 in our blend. Every batch is independently tested by HPLC to ≥99% purity before it is listed, and carries a batch number that links to its certificate of analysis.
