DMAA Pre-Workout Stack - Jack3D clone with massive pumps (by Bobertsawesome)
Jack3D was a great product but is no longer being sold (unless you want to spend $75 for a bottle). Jack'd Up is an exact clone with added extras but the NOs and other ingredients aren't awesome. They're very impressive but not 100% there yet, with PES High Volume you get every non-stimulant booster you could imagine.
This is a perfect combo, DMAA will always have the best mind-muscle connection and the ingredients in High Volume will have your muscles almost bursting.
