ALL OF THOSE COMBINATIONS ARE GOOD
NYC
the norephedrine, yohimbine, caffiene stack
is best for dieting because it does have great appetite suppressant effects as well as thermogenic ones. It is also highly reccomended for those wishing to avoid extreme stimulatory effects and the subsequent crash.
EC(forget the aspirin)- is better for pre workout intensity- it will make you more jacked- many women find the EC stack unpleasant even nauseating- an effect not seen with NYC- from a dieting stand point it is less effective-less appetite suppression and the lack of yohimbine to block NE activation of the A2.
I think that both should be used- alternating two weeks on two weeks off- though different patterns may be used. though many people find the more even stimulation provided by NYC to be more palatable and thus maintainable- for many the CNS effects of EC are too unpleasant.
TOPICAL YOHIMBINE- stacks well with either.
