Hot take: Dosing the whole game is "start low" Adult replacement commonly begins around 0.450.9 IU/day (somatropin is quoted in both mg and IU: 0.2 mg 0.6 IU), then titrates gradually every four to eight weeks against symptoms, side effects, glucose, and age-adjusted IGF-1

A scoping review in Cureus (2025) added important context: dual-acting agonists like tirzepatide which targets both GLP-1 and GIP receptors produced greater reductions in weight and insulin sensitivity than GLP-1-only agents
