GLP-1 receptor agonist. Work out exactly what to draw for your own mix, see the doses used in research, and follow a week-by-week plan. Evidence tier: clinical.
These are long-acting and reach steady state over weeks, so a single day’s timing has little effect. Consistency matters more than the hour.
