How to read this list

The BPC-157 TB-500 references below are the complete cited basis for this site. Citations 1-5 are the constituent studies — the established single-compound mechanisms and the flagship tendon finding. Citations 6-8 are the recent systematic and narrative reviews that bound the evidence honestly. Citation 9 consolidates the dosing-context and human-data record. Citations 10-12 are the FDA sources for the regulatory and access page. No claim on this site is made without a numbered source here; where a claim is blend-level, the citation establishes that the controlled evidence does not exist. The full set is gathered as the Wolverine blend references index.
