Bought two cans of this recently. As I am a good responder to Vaso6, I figured this would be an effective pump agent. Used it for three workouts in which I got absolutely no pump whatsoever. I would have got more off 250mg of Agmatine. I was led to believe that this company puts out good products and I was going to buy others; however, this product was not filled what it says its filled with 100%. Be warned.
