Description

TB-500 (TB4), 10mg

TB-500 is a synthetic peptide associated with the Thymosin Beta-4 (TB4) sequence, and it is commonly referenced in the literature under the name TB-500. It is supplied strictly as a research-grade reference compound for in-vitro and laboratory research use only, and is studied as a model peptide in cell-biology and protein-chemistry research. This listing describes the compound’s identity and use as a research reagent only. It makes no claim regarding any biological effect in humans.

About the name

“TB-500” is used in different ways across the market, sometimes for a short fragment of Thymosin Beta-4 and sometimes for the full protein. Rather than guess, we go by the lab: this product’s certificate lists it as TB500 (TB4), and Thymosin Beta-4 is also what the lab identified in our BPC-157 and TB-500 blend.
