I have taken it off and on since I was 16 (8 years). Took it before football practice in HS, used it in the Marine Corps, for fat loss, recreationally (yes, I like the feeling), and now for that edge in the weight room. The longest I went taking it just about every day has been 8 months and the only "ill effect" I got was that I had to take increasingly larger doses toward the end of that period to get the same effect (up to 200mg/dose sometimes 2x/day). This was in 2000 in the Marine Corps. I took some time off of ephedrine after that and everything went back to normal (25mg made me sweat like a horse). I have had ekg's and stress tests over the last 4 years and have never had a single issue on either. If you have heart probs to begin with, probably not a good idea, but as for ill effects, I have never noticed any besides desensitization (and the occasional night of lost sleep here and there
). What is your idea of a "long period of time"? More than 8 months? And what dose?
