Hi, my name is Anthony and I'm on day 3 of 14 of my Ephedrine/Caffeine stack (200mg Caffeine/26mg Ephedrine HCL). I'm 19 years old with a high metabolism and I'm approximately 126lbs/5'5". I work out 3-4x a week and have done this before. But I feel a bit worried that this could be bad for my mind or heart in some way. I'm jittery and a bit paranoid/worried. I have done extensive research on the EC stack and I do it correctly and only once in awhile. I drink plenty of water and when I do cardio, I make sure it's light(my heart rate should not exceed 160bpm). I don't know if there are any long term effects to this if I continue to do cycles every once in awhile (usually every few months when I have some extra money for an ephedrine cycle). What is your opinion on this to lose some body fat for a bit better shape? Should I not do another cycle later on? Should I be worried about being addicted to working out?
