Different people have different diet and fat loss management needs. Some people what the Thermorexin energy and want something for fat loss AND appetite suppression. Others want something like Cardio Breeze for energy and fat loss but want something they can use on an empty stomach.
Levorex is stimulant free and a lot of people like that because you can use it alone or if you do add it to your stimulant fat burner like Thermorexin it increases your fat burning without jacking you even higher.
SesaPure is great because you don't have to be so strict with your diet. It causes fat loss even during a normal diet, and again, no stimulants. You add Glucorell because it stops the excess insulin from halting your fat burning.
Yohimburn ES is for problem areas.
