you apparently don't understand how creatine works.
the only reason not to use creatine on a cutting cycle is if you start taking it, you'll retain some extra water, which will affect your weight by a few pounds. it can be discouraging, because you really are losing fat, but the net weight loss is 0 because you hold a few extra pounds of water.
after 3 weeks, you hit creatine saturation, and thus water saturation, so then you finall start seeing weight loss on the scale.
