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.
