everyone is different when it comes to stims, personally for the first two weeks 100mg of caf twice a day is more then enough for me. I will usually up it from there as a tollerance builds. Just make sure your taking in enough water, and make sure to count however much caf is in san's tight and add that to your daily estimates.
