USP Labs have had their original pre-workout concentrate Jack3d in the backgrounds of the supplement marketplace for some time now. It has remained available in a number of stores in various flavors most of which were released after the original three, grape, lemon lime, and tropical. For example you can still find the original Jack3d at GNC in fruit punch. Unfortunately for those who were hanging on to those last USP DMAA sources. The brand will be discontinuing the generation one formula and replacing it with the tentatively titled Jack3d Advanced Formula. Nothing has been said about the supplement and it’s contents apart from it’s booting of 1,3D. Although USP Labs have confirmed that the reformulated Jack3d will contain, like the original, a total of 45 5g servings, and be available in the Micro inspired flavor blue raspberry.
