Got on a GLP-1 back in 2005 knowing it would likely become forever medication. Also understood unlike insulin, coverage isn't guaranteed, so staying on it indefinitely wasn't a sure thing. Once byetta shifted from twice daily to once daily, I realized every future version would live or die by whether it did the job it was designed for, and a small formula tweak could just as easily make it useless. Across twenty years on GLP-1s I've seen the full range, meds that worked great, worked weakly, or failed completely. With original semaglutide, 0.25 did nothing for insulin needs and A1C kept climbing, while 0.5 helped active insulin needs but not background insulin, though it stabilized A1C. 1mg knocked down background insulin further but stopped helping A1C, which honestly was a relief.
