Jefferson Steelflex asked:


I take 400mg of caffeine a day and they're not working like they used to. I take both of those tablets when I first wake up. Would it help me get more energy and speed up my metabolism if I take 600mg a day but only take 1 every 3-4 hours instead of one time? Would there be any health risks at 600mg a day? Would it give me more energy and speed up my metabolism better if I take it every few hours instead of all at once? Sources?
I'm 16, 5'5", and 140 lbs.
Caffeine tablets give me enrgy without the fatning calories.
