BPC-157 and TB-500: A Comprehensive Research Review
BPC-157 and TB-500: A Comprehensive Research Review
BPC-157 and TB-500 (Thymosin Beta-4) are among the most widely researched peptides in the context of tissue repair and cytoprotection signalling. This review summarises key findings from the research literature.
BPC-157 (Body Protection Compound-157)
BPC-157 is a synthetic pentadecapeptide derived from a protective protein found in gastric juice. It has been studied extensively in models of gastrointestinal, musculoskeletal, and neurological tissue signalling.
TB-500 (Thymosin Beta-4)
Thymosin Beta-4 is a naturally occurring 43 amino acid peptide that plays a central role in actin polymerisation and cell migration. It has been studied in wound healing, cardioprotection, and inflammatory resolution research.
Mechanistic Overlap and Differences
While both peptides have been studied for tissue-supportive properties, they operate through distinct mechanisms. BPC-157 primarily modulates angiogenesis and nitric oxide pathways, while TB-500 acts primarily through actin sequestration and gene expression modulation.
