How to read this list

Every bracketed number on this site — [1], [2], and so on — points to an entry below. The list spans the founding 1998 selectivity paper, the human pharmacokinetic study, the failed Phase 2 trial, the preclinical bone and body-composition work, and the 2024-2026 studies and reviews that make up the recent-research frontier this digest leads with. A few entries are class-level or scaffold studies where ipamorelin was not the tested molecule; those are noted in the text where they are cited so no finding is misattributed.
