It's good. It's fiendish.
This is for proper tweaking. Ive only taken 2/3 scoop max and I wind up staying in the gym an hour longer than usual, banging out reps that are normally exhausting with ease. The long term health consequences of this are probably dire but I still highly recommend it. This was delivered in good condition as well (some things from this site don't)
Surprisingly no crash? Ive had some of these ingredients before and I'm used to them causing pretty brutal crashes. So I'm not sure if it's just that I took less or what
