With creatine monohydrate, there is usually a loading phase. The maintenance phase is about 5 to 10 grams daily - depending on your body weight. To see the best results, start by taking 4 20-gram servings of creatine monohydrate powder a day for 5 days. You can also do a longer loading phase, taking 10 grams a day for 10 days, then switching to the maintenance phase.
