Oh man. Studies usually begin retatrutide at 2.5 mg, which matches what you did. It doesn't produce noticeable sensations for most. Stick with that amount for a full month prior to any increase. Many don't notice reduced food thoughts until higher amounts, but you might feel full sooner after eating less. It takes about a month to build up fully. Rushing the dose can lead to more side effects like elevated heart rate. What's your aim with it - shedding fat or total weight drop?
I mixed up my 10 mg vial using 2 ml and then injected 0.5 ml, though I'm second-guessing if 1 ml would have been better. Could someone give me some guidance here?
