METHOD
Numbers stay if a paper or an official page supports them.
Phases are from Miller 2011. Sleep studies before GH are from the 2024 UK guidance and a 2022 sleep-medicine review. Drug status comes from FDA and ClinicalTrials. Gastric steps come from association alerts. Posters are labelled as posters.
