About this material

What it is

A short fragment of the thymosin β4 sequence, supplied lyophilised under nitrogen and released at 98.8%. Frequently ordered with BPC-157 as the two-vial tissue-repair reference kit, where both component certificates remain individually traceable rather than being merged into one kit-level document.
