I have been using doing clen. 2 days on/2days off. On the (2) days off of clen I am using 10-20mg. of adderal. I find that it is better than any ephedrine related compounds I have used, because it gives a thermogenic effect, like ephedrine related compounds, but it also gives you more concentration. It helps you stay on task with your workouts and with your eating plan....It also curbs your appetite, like ephedrine related products. One thing adderal does not do that ephedrine does is that it doesn't give me heart palpitations, which is surprising. HERE IS MY QUESTION HOWEVER...How catabolic is adderal in the small doses I am taking??? For anyone that competes and has used adderal, or anyone that has any general knowledge on it, please give some input, it would be greatly appreciated, thanks
