Confused of dose

Hey guys. I’ve been on it for 3 months and started with .25 (25units) , then .5 (50 units) , then 1 (100 units) And I just received my new batch of meds. I’m supposed to start 1.5 today but the medication says inject 0.6 (60 units) and the needles I got are the same exact gauge and size and the ones I was using before. So wouldn’t this be going down in dose? Any help is appreciated!
