sure try caffeine, you should notice and effect pretty quickly.
try geranamine in AMP, quite the stimulant in my books. Surely caffeine or ephedrine have shown effects. What about belladonna have you tried that, i bet you would notice effects from that

That's a bit of a cheap shot. In my posts you can see that I said I agree that E, C, and A have an effect, just like e.g. cardio. The question was not if there are supps which have any effect at all, the question was, do they have the effects desired for bodybuilding. I never tried E, but C and A did not improve the ratio of fat loss vs. muscle loss at the same rate of weight loss (than without them) for me.
