I would like to know if someone take steroid, did he must stop all other stuff like protein, creatine, arginie, glutamine and fatburn ?

Of course not bro, you must combine all these.
Using steroids doesn't mean that you have to eat less or train less, you must improve your routine, it depends on what are you going to use.

bump - if anything you will want to train harder and eat better to get the best possible gains
