Remove limits to muscle growth.
If there is one supplement that you use consistently, it should be creatine. Study after study confirms that it works to increase muscle size, strength, power and endurance. New research continues to pile in which shows it has many benefits.
Researchers from the Arak University (Iran) reported in a 2010 issue of the Molecular and Cellular Endocrinology that subjects taking creatine while on a eight-week weight lifting program had significantly lower myostatin levels than those taking a placebo. Myostatin is a protein that limits muscle growth. The Iranian researchers concluded that since myostatin levels were lower in the subjects taking creatine, one way that creatine may work to increase muscle size and strength is by reducing myostatin levels. That, in turn would reduce the limitation that this protein places on the muscle growth.
