How often should i take creatine ethyl ester?

Yeah, basically ive just started a workout. well have been doing so for a few months but no change. So i've started to take Whey Protein shakes and WILL be purchasing Creatine caps. Ethyl Ester to be precise. Anyhow, how often shall i take it? Like one tablet a week? per work out? I literally have no idea.
