What is TB-500?
TB-500 is a name used for synthetic peptides based on thymosin beta-4 (Tβ4). Thymosin beta-4 is a 43-amino-acid protein found in most human cells, where its best-known role is binding actin, a building block of the cell’s internal skeleton. In the research-peptide market, “TB-500” is used for two different materials: synthetic full-length thymosin beta-4, and a short seven-amino-acid fragment of it (Ac-LKKTETQ, residues 17–23). Check the certificate of analysis for your batch to confirm which form you have.
TB-500 product specifications
- Compound: TB-500 (thymosin beta-4 related peptide)
- Reference protein: thymosin beta-4, 43 amino acids, about 4.9 kDa (gene TMSB4X)
- Vial sizes: 5mg and 10mg
TB-500 in laboratory research
Thymosin beta-4 and peptides derived from it are studied mainly in cell and animal models, including work on actin dynamics and cell migration. Results from those models cannot be taken as evidence of safety or effect in people.
Regulatory status
TB-500 is not an approved medicine in the US, UK, EU or Canada. Thymosin beta-4 and TB-500 are prohibited in competitive sport by the World Anti-Doping Agency. This product is sold for laboratory research use only.
TB-500 compared with related products
- BPC-157 is a different peptide and is often studied alongside TB-500.
- Combined vials: BPC-157 & TB-500 Blend and BPC-157, TB-500 & GHK-Cu Blend.
- Thymosin Alpha-1 shares the “thymosin” name but is an unrelated peptide.
Available sizes: 5mg and 10mg
TB-500 is offered in two vial sizes: 5mg and 10mg. Both contain the same peptide. The figure is the total amount of peptide in the vial, supplied as a dry (lyophilised) powder; it is not a concentration, so a larger vial is not “stronger”, it simply holds more material.
