Nitric Oxide (N02) is currently one of the most recent and most popular forms of supplementation currently available. Nitric oxide can help develop strength, stamina and pump up the body for more exercise. It is also believed to be a very effective fat burner for people trying to enhance muscle definition and reduce excess adipose tissue. Nitric Oxide works by causing the muscles to dilate, which releases more blood and results in feeling instant muscle growth. Incorporating Nitric Oxide with exercise means that the micro-tears produced as a result of high intensity exercises heal quicker, and this increases muscle size and mass.
 

NO2 gives users a "perpetual pump" that lasts long after the workout is over. There is also a massive motivational, almost placebo-like effect with this supplement. This is because once taken, the brain and the body are led to believe that they are stronger and more powerful.
