Looking for guidance regarding fat burners. The one I am considering is non-stimulant and contains Garcinia Cambogia as its main ingredient. Looking for non-stim so as not to compete with my pre-workout, which has caffeine. Will this suffice? It is not a thermo type fat burner. What type of fat burner is recommended? There are so many, some which seem to be mostly appetite suppressants to others that are loaded with caffeine for “extreme” results. Thank you
