Creatine monohydrate is absorbed by the muscle and is believed to increase the rate of protein synthesis in the body. A higher rate of protein synthesis puts the body into an anabolic state. EAS was the first to introduce it, but almost all creatine is the same. A company called ‘Pfanstiehl‘ makes about 40% of all the creatine produced in the US. You can get 1000 grams of creatine for about $25.
