2. Molecular origins — gastric BPC vs thymosin beta-4
BPC-157 is a synthetic pentadecapeptide (15 amino acids) with sequence GEPPPGKPADDAGLV. It is derived from a fragment of the human gastric juice protein Body Protection Compound, identified and characterised primarily by the Sikirić research group at the Unive

- BPC-157 is a synthetic pentadecapeptide (15 amino acids) with sequence GEPPPGKPADDAGLV. It is derived from a fragment of the human gastric juice protein Body Protection Compound, identified and characterised primarily by the Sikirić research group at the University of Zagreb.
- TB-500 is a synthetic peptide based on the active region of thymosin beta-4 (TB-4), a 43-amino-acid naturally occurring peptide expressed in most mammalian cells. TB-500 is typically sold as a 17-amino-acid peptide encompassing the biologically active region (residues 17-23) responsible for actin binding, and can refer to either the N-acetylated LKKTETQ heptapeptide core or longer sequences surrounding this core.
- The origins are biologically quite different: BPC is a gut-protective fragment of stomach protein; TB-4 is an intracellular actin-sequestering peptide expressed broadly across tissues.
