"The recommended dosage for a normal person is 5 grams per day. And if you think that taking 10 grams creatine per day you will gain twice, then you are absolutely wrong. Once the muscles have reached the saturation point - all extra creatine that you will be eating will just go waste and will be just excreted out as a waste product."

Your body reaches saturation -- and then cannot absorb any more.
"You've seen those sick bodybuilders chugging down 10-20 grams of creatine. Is it worth it? According to scientists at St. Francis Xavier University in Nova Scotia, at 0.1 grams per kilogram of bodyweight, male athletes excreted 46% of the ingested creatine within 24 hours. For a 220 pound lifter, this means that if he consumes 10g of creatine, 46%, or 4.6g of creatine, is wasted. In another study performed at the Human Performance Laboratory at Ball State University, scientists confirmed that lower doses of creatine monohydrate (5g/day) are effective, and that results can even be achieved without a loading phase."
