Fishing Romex Electrical Wiring through Conduits that has three 90 degree Elbows

I want to use 12/2 romex wire which I want to fish it through 1/2" conduits. I am installing 5 outlets in the garage, first outlet will be a GFCI. It seems there are quite a few so called electricians who, in my opinion, do not know the NEC code(s) in reference to what I want to do/or use. Too many conflicting answers to my concern.
