I dont recommend Lipo6, combining Yombine HCL with Guggulsterones is not a good idea. My brother noticed increased heart rate and dizziness well on Lipo6.
I personally recommend you go with a non stimulant and see how well you respond to them before going to a stimulant. Some good non stimulant are Sesamin, Melting Point, LipidFX. A good non stimulant stack would be either Melting Point+Sesamin or LipidFX+Sesamin.
If you feel the need for a stimulant then I recommend you look into Man Scorch, Basic Cuts, Thermal Rage.
Diet is most important, supplements do have their place. But diet comes first, it will make or break you so make sure your diet is in check.
