There are side effects with all supplements including protein powders. Even with protein powder, especially if you just started using it, you can have a bad stomach/wind. Creatine makes you lethargic if you don't drink enough water and can disrupt your sleep. Those are just small side effects.
Protein powders aren't a steroid though, they're a food source.
No, protein powder is not necessary for any fitness goal. If your goal is to build muscle then you will require a set amount of protein intake per day, all protein powder does is help you to reach that target but it can be done easily enough without it.
