Muscle gainers do require more protein than ordinary people. For general muscle gainers, 1.6-2 grams of protein per kilogram of body weight per day is enough to meet their needs. The excess protein cannot be used by the body. On the contrary, excessive protein is harmful from a medical point of view and will increase the burden on the human liver and kidneys. In addition, a large amount of protein will produce a lot of toxic waste during the metabolism process, causing dehydration and acidification of body fluids, weakening the training effect.
