I have decided that i am going to start taking creatine. Which brand of creatine is regarded as the best and most widely used (ie. Safest but very effective). Also, how do you use it correctly, like when do you take it, how many times a day, and what do you mix it with for maximum results? I am currently 5'7 at 135, i was 130 about 4 weeks ago, and i hope creatine will help me fill out more and get stronger. Thanks.
