ephedrine puts a big toll on your cns too. for some reason, clen is much better for me personally. i take too much ephedrine and i get chest pains like like you wouldn't believe. with the clen, my bp never went up, my hr only went up a very small amount, and i got much better results as far as decreasing bf% and it even helped me increase lean muscle mass while i was on a calorie-restriced diet. my only issue i had on clen was it gave me a lot of anxiety and once when i was doing cardio at too high of a hr (160bpm), i started having funny feelings in my chest which lasted for about 10mins. after cooling down. then again, i know now i shouldn't have been doing my cardio above 140bpm while on the clen, so that was my mistake. oh, and this stuff did wonders for my asthma while i was on it too.
there is some research that will say clen is worse and others saying the opposite. it's highly controversial and really does seem to be dependent on the personalized experience while on it. however, as long as you monitor your rhr, bp, cardio hr, and body temp while on clen, you should be fine. if you combine clen and t3, that will be far more effective than eca, but again you're increasing your risk for side-effects, though not necessarily heart issues since t3 doesn't seem to affect the heart.
