The body's can't store protein, and people vary widely in their daily protein needs. Recommendations from the government (0.8 gram of protein per kilogram (2.2 pounds) of bodyweight) totally contradict what many hardcore actually do (1 gram or more per pound of bodyweight), but the truth for you may lie somewhere in between. Whatever your protein needs, if you exceed them without following an accompanying mass-building program, the excess calories won't translate into muscle. I believe in small amounts throughout the day builds mass muscle without fat gains far more than large amounts of protein at one time (See Grazing). Also, if you aren't eating enough carbohydrate, you'll waste that precious protein on the fueling of basic metabolic processes and daily activity. In some cases, when people increase their protein intake drastically and then gain muscle, it may not be due to protein intake but to raising their calorie intake to a point at which growth can be supported. A final thought on protein: If your kidneys aren't in good shape, or you have kidneys disease, using excess alcohol, steroids, or any other medications that are hard and the kidneys and liver, a high-protein diet isn't a good ideal. You should determine a proper protein intake only.
In closing, remember that protein powders should be treated as a supplement to a food-based diet. Ideally, you should eat a variety of protein sources throughout the day, as well as enough carbohydrate to provide energy and prevent the protein you consume from being broken down to fuel basic energy needs. Any protein supplement, and long as you consume it with a a well-balanced mixed diet of different proteins, then all of your amino acids bases will be covered.
