It works, but the market hype makes it sound far better than it is. I took it, and now I'm trying to get a roid hook-up....that should tell you something. If you juiced before, you would think it ain't worth pissing on, but if you're like me and never juiced(want to like hell) then you would actually get something out of it. I don't know the scientific reason for this, but lets face it....nothing on the legal market can come close to touching roids.
Obviously, nothing is as anabolic as juice, not even close.
As for the pumps, I could tell a big difference, but after 1:30-2:00 hrs, my pumps would be history.
