Doses of pure creatine monohydrate typically cited in the scientific literature range from between 2 and 25 grams per day for an average framed male (70 kilograms/154 pounds).

More isn’t necessarily better. The actual amount of creatine monohydrate taken in a single day should never exceed more than ten-times your normal daily turnover of creatine. Creatine turnover is a function of total muscle mass and for an average sized male is rougemy 2 grams per day. Therefore, an average sized male (70 kilograms / 154 pounds) should never take more than 20 grams per day!
