Prolific for me is a good no wasted ingredients PW and at 2 scoops it delivers BUT PES needs to drop that L-Theanine down to 50mg a scoop so you can feel the not so high stimulant blend better when you do use the 2 scoops. There have been times when I used it and really didn't feel the stimulant effects at all and I don't need a caffeine break cause I only use caffeine or stimulants before I train. I've given samples of this PW to others to try and they also commented that it tasted good, pumps were good but they didn't feel the stimulant effects.
