Takes about a hour to kick in and feel anything, that's with adding coffee in the morning. And any energy or uplift that you get from this supplement only last 2 hours, if lucky. No offense, but VPX Meltdown works 10 times better. VPX worked wonders with out the so called, Ephedra extract. Plus, the caffeine content doesn't even match the average 200mg in most supplements containing it. Save the money and buy a product that delivers results. Such as VPX Meltdown or Lipo 6 (original).
