Its not bad, Ive taken it along with many others. But let me tell you about the best freakin energy/mood supplements I have yet come across in years...
ALRI's Venom Hyperdrive 3.0, And they just came out with the new formula called 3.0+ I have no doubts about it being even better. Cleanest, best energy supplement Ive taken to date!!! by a long shot!
