Creatine is the most popular and effective supplement on the market for building muscle. Our bodies naturally produce creatine, and it is used to supply energy to our muscles. Creatine is 100% natural and can be found in many of the foods you eat, including beef, salmon and tuna. Creatine can increase overall lean muscle mass in less than two weeks in some cases.
There have been over twenty studies done on creatine that have shown increased energy levels as well as increased strength and endurance while reducing recovery time. These studies also have not found any adverse effects from the use of creatine whatsoever.
