SOURCES

The twenty-one sources this desk is built on

Fixed, numbered once, and never renumbered — every bracketed figure on the site points here.

How to read this list

The list below is the complete set of sources cited anywhere on this site. It is numbered once and the numbers never move, so a bracket in the text always resolves to the same entry.

Five entries cover BPC-157, five cover NAD+, seven cover semaglutide and four cover tirzepatide, with one head-to-head trial serving both incretin compounds. Nothing is cited in the text that is absent from this list, and no source appears here that is not used somewhere.

Where a documented caution on a compound page carries no bracket, that is deliberate rather than an omission: the concern is real and documented in the audited material behind this site, and no paper on this list supports it directly. Attaching the nearest available number would look tidier and would be wrong.
