I have taken many different pre workout supps including no xplode, super pump 250, NO vapor, and a few others. Granted I have only taken jacked four times now, but to this point it is by far the best thing that I have tried. I felt incredibly strong and was extremely intense throughout my workout. I felt pumped before i even touched a weight. I will post again once i finish the container to see if the results decline over time. Great product at a great price, fuck muscletech. |
