Switching generic brands fin 1mg

Hi guys I recently ordered some more 1mg pills and they sent me milparm which I’ve been on for maybe 2 months now. (Think I was on relonchem before) and I think I’ve noticed a tiny amount of progress lost. I haven’t really been taking pictures from the year I’ve been taking the medication but I did make some decent progress. I’ve also read other people saying the same thing about milpharm. Should I keep up with this supply or switch to another? I could maybe get these accord below. Any help is appreciated.
