The way you are using tirzepatide makes no sense at all. The standard schedules and step-up rules were created through actual research and they work. These drugs need time to reach a steady level in the body. Jumping between 7.5 mg one day and much higher amounts a few days later will not produce reliable results. Adding retatrutide on top of that same random pattern would only make things worse. Get a consistent schedule in place first and then check how you feel after four weeks. These medications are not something you can just blast for an immediate effect.
Right now I use tirzepatide in a loose way, adjusting the weekly amount between 7.5 mg and 15 mg and sometimes splitting it. Last Thursday a 7.5 mg shot felt too weak so I added 11.25 mg on Sunday and things have felt right since then. No negative reactions at all. I am thinking about bringing in retatrutide but do not know the smartest way to do it. Maybe I should switch to a steady routine with both drugs instead. Still, the loose method has worked fine because I just pay attention to how I feel. How have other people handled adding it? Keep the tirzepatide amount high while starting retatrutide low, or the opposite? So far I have only used tirzepatide.
