I had the raspberry lemonade flavor which is okay. As far as pumps, it worked, but there are far better pump products out there, such as Spartan Nutirition Pump or Alpha Lions pump product in my opinion and both taste better.
Had to cut back on Stem preworkouts but still wanted a good pump during my workouts. This stuff does the job pretty well though had to give a 4 star because seems it was exposed to moisture.
This is hands down the most effective pump product I have used. It is definitely worth the price.
