Every quantitative claim on this site traces to one of these studies. PubMed and DOI links for each.

How this list is used

This is the complete reference list for the Ipamorelin digest. Each numbered entry corresponds to the bracketed citations throughout the site, so any figure — the ~2-hour half-life, the swine ED50, the failed-trial p-value — can be traced to its source. The list leans on the small body of human ipamorelin data (the PK/PD study and the single Phase 2 trial) and the broader preclinical and class-level literature that frames the mechanism and safety. Links go to PubMed or the DOI of record.
