TB-500 (Thymosin Beta-4)

Thymosin Beta-4 (TB-500) is supplied as a lyophilized powder in a single sealed vial. Thymosin Beta-4 is a 43-amino-acid, naturally occurring protein (almost all cell types make this) [1]. The peptide in our TB-500 5mg vials is an acetate of the same, not a short fragment (as other TB-500 vials are). The acetate salt form of Thymosin Beta-4 makes it more stable and soluble for lab research. The term “TB-500” is used for both, the full-length Thymosin Beta-4 molecule and its shorter active fragments, depending on the supplier. But as you’ll be able to verify from our Certificate of Analysis, our TB-500 is precisely an acetate of the full-length Thymosin Beta-4. Our products come with maximum purity, HPLC and MS verification, and a COA. Made in a WHO/GMP, ISO 9001:2015 certified EU manufacturing facility, our TB-500 includes no unnecessary additives. If you’re looking to buy TB-500 (Thymosin Beta-4), there are two ways. You can either buy the TB-500 directly here on this page, or go for the BPC-157 + TB-500 blend, which is the protocol many studies require.
