There is absolutely no need to cycle creatine. All it is is an amino acid. If you don't get enough in your diet, your liver can synthesize it, but it can only produce ~2g a day. By supplementing creatine, you get more than you otherwise would. That's like saying that you need to cycle protein, makes no sense.
Loading can help you see results faster as the creatine transporter is saturated faster. But once it's full, it's full.
