I recently just started taking 40mg Adderall everyday (20mg 2xday) for ADD. Just wondering if I should be worried about taking these with pre workout supps like jacked or NOxplode? And also should I be worried about my heart rate being higher when I do cardio or while im lifting. Doc said not to worry but they dont always know everything, especially since my doctor weighs 160 pounds soaking wet. thought i would ask some people that might have some experience. btw im 5'11' 235 pounds. been lifting for 8 years. thanks.
