I've started working out again, been going at it for a few months now. Not lifting super heavy weights yet, trying to gain weight. Is creatine a good idea? Anything to watch it for, as far as brands, side effects, etc? I've been trying to read up on it, it sounds pretty safe but I'm new to all this stuff.
You don't really need it. It helps but it's like 10% more strength and endurance, it's not a huge difference.
Personally I don't like it, it made me nauseous and I didn't even take that much of it. If I ever wanted to train more often I'll consider it again but right now I don't feel like it's necessary.
Just eat a bunch of protein you'll be fine.
