Local precision meets systemic coverage.
The BPC + TB stack pairs a local-acting pentadecapeptide (BPC-157) with a systemic thymosin β4 fragment (TB-500). Preclinical research has treated the two as complementary: BPC-157 is associated with site-specific angiogenesis* and tendon-to-bone healing, while TB-500 is investigated for its systemic actin regulation* and cell migration activity.
Combining the two allows a single protocol to address both an acute local injury and the broader recovery demand* placed on surrounding tissue. In practice, this is how operators who have tried each peptide individually often end up dosing.
The stack is shipped as two independent vials so each compound can be titrated and reconstituted on its own schedule.
Every lot ships with an independent Certificate of Analysis on file. Below is the format your lot's COA arrives in — HPLC chromatogram, identity, endotoxin, the works. Request the document for the exact lot you receive.

“Both vials in the stack had matching lot dates and individual COAs. The packaging held up across the country. This is the third vitalitiRX order — process is consistent every time.”
“Bundled shipping, cleaner unboxing than ordering them as separate products. Customer service confirmed compatibility before I ordered, which was a nice human touch.”
