I have been Taking Dexedrine for about 4 years now, I have had the Glaxo name brand years ago before I was even prescribed it. I have always taken the Barr brand for my spansule and my IR's. I recently found another pharmacy that said he could order them for me because I like the Xanax he gets better then my current Pharm (he has the yellow bars) So I asked him about it and he said they would be from Core. Does anyone have an opinion on what is better? Or are they pretty much the same? Let me know your opinions please. I have noticed My dex isn't working as good lately. I take 3 15mg caps and 2 5mg IR tabs a day.
