not sure what the totals are but I do use a pre w/o that has caffeine, green tea, creatine, arginine, etc etc, and Ill use a bcaa drink during my w/o. there both I satori brands which ive been very impressed with the products. The pre w/o gets me going and I have found the bcaa keep from burning out to early in the w/o so I can work as hard at the end of the w/o as I do at the beginning. I find myself wanting to keep going and looking for additional lifts to add in at the end instead of deleting lifts or sets. I was kinda surprised to see posts discouraging the use of bcaa because of how much I seem to get out of them.
