BPC-157 / TB-500 is a research peptide blend combining two well-studied synthetic peptides: Body Protection Compound-157 (BPC-157) and Thymosin Beta-4 fragment TB-500. BPC-157 is a stable gastric pentadecapeptide originally derived from human gastric juice, while TB-500 is a synthetic peptide modeled after the naturally occurring thymosin beta-4. Together, this blend is formulated for laboratory research focused on tissue repair, angiogenesis, and cellular regeneration pathways
