If i remember correctly you are not from the US either, so getting ephedrine could be more difficult, but since you can get it and wan't it, it's another story. I have pills called: Dymetadrine with: 20 mg ephedrine hcl, 25 mg bromelase, 200 mg caffeine and 200 mg aspirin. I don't really take these eiher, they just sit in my closet waiting for a rainy day. When i did try it, it was more than enough. If i were you i'd split the E down to 50 mg and take it three times a day, it's just because of the half life and taking 150 at a time is too much, unless you are an ex-junkie and in that case should stay away from it alltogether. In any case 150 at a time, could cause arytmia, high blood pressure and diarrhea. And not like "steroids cause cancer" but in away that's more than likely. If 50 mg at a time is not enough take something else or let your tolerance build again.
