The 21 citations behind the claims made across this site — clinical trials, meta-analyses, and regulatory references.

## How to use this list

Every bracketed number that appears in the body text of this site — like [1] — points to one of the 21 sources listed below. Each entry links to its original source: a PubMed record, a DOI, or, where no PMID exists, a direct regulatory or clinical-reference link. Citations 1-7 support the semaglutide page, 1 and 8-11 support tirzepatide, 12-16 support tesamorelin, and 17-21 support BPC-157.

API Peptide traces each compound from lab molecule to (sometimes) licensed drug and back only as far as the citation trail actually goes — an editorial desk, not a clinic, a pharmacy, or a source.
