i wouldnt exactly say that using creatine during a cycle is a waste but most people i know who do use creatine stop its use while cycling. if you use winny or something else that may dry you out and you start to get sore joints/muscles from it then that would certainly be a good time to use it during a cycle.
im sure it wont hurt though to keep using it unless your funds are low and you would be better off saving it for a better time.
