A fixed-formulation 1:1 research blend containing **5 mg BPC-157 and 5 mg full-length thymosin beta-4 (TB4) per vial**.

BPC-157 is a synthetic pentadecapeptide commonly investigated in research involving tissue integrity and repair-associated signaling. Thymosin beta-4 is a naturally occurring actin-binding peptide studied for its roles in cell migration, tissue remodeling, and related cellular processes.

This formulation contains **full-length thymosin beta-4 (TB4), commonly marketed in peptide research as TB-500 — not the shorter TB-500 fragment (17–23).**

The two components are supplied together in a fixed 5 mg / 5 mg formulation. Lot-specific independent testing is available through the CS Research Testing Library.
