Bear in mind that I have never used creatine and this is only from a biologists point of view.

One

month should be fine for an off cycle (perhaps even less), as you piss out creatinine (waste creatine) every day.

Creatine is basically your muscles source of energy (do you know what ATP is? Well, sort of like that, it carries

the energy untill it can be used up), so it should be a relatively safe suppliment if used sensibly.

P.s.

consider taking a calcium supp. aswell, as that is very important in muscular function.
