How to read this list

This is the full reference list with PMIDs and DOIs for the BPC-157 TB-500 digest. Entries 1-9 are the peer-reviewed mechanism, efficacy, identity, and review literature for the two constituents; entries 10-12 are the FDA primary sources behind the regulatory and access statements. Where a peptide finding is attributed to "TB-500," the underlying source frequently studied full-length Thymosin Beta-4 — that distinction is preserved in the citations and throughout the site.
