sr9009 helps with metabolic disorders... it was first called exercise in a bottle because they were testing it when being completely sedentary and it was burning fat... gw also helps to increase metabolism on top of its capabilities to drastically increase vo2max, which then clearly lets you do FAR more in terms of cardio training and muscular endurance, which is huge for burning fat... you cant just sit on your ass and expect to burn large amounts of fat but when they give you this capability, you can accomplish FAR more than you ever could on your own
