I think most creatine supplements that are simply 100% pure creatine are fine. It's probably more risky when you start looking at other products that are a 'blend' of different ingredients. If you are new to weights then you could probably hold off for a while, just get your nutrition on point and get into a consistent routine with your lifting. Supplements should always be just that ~ supplemental to a good diet and training regime.
