I used this preworkout for the past few weeks. I like this stuff. It works pretty good. It would be nice if it didn't have so much creatine monohydrate in there. Flavor's not bad, but it gives me a bit of stomachache for a few hours after I drink it. I'm really hungry after I work out, so I eat a bunch and the stomachache goes away, so it's no big deal. It gives me really good energy, decent pump, and noticeable beta analine. It's got 1-Andro in it, but I don't know how much. All in all, good stuff.
