the reason you like jack3d is because of the 1,3 dimethylamylamine. several other supps have it in them (phenadrine, AMP, etc). hard to find it by itself since bulk nutrition stopped selling it. sucks that all those supps have caffeine in them because straight 1,3 dimethylamylamine is better in doses around 250mg. you'd be consuming more than 600mg of caffeine to get that dose with jack3d, phenadrine, etc.
also, arginine, beta alanine and creatine are worthless for energy. they're included in jack3d to increase muscle edurance/volume during workouts. for mental/CNS energy you're better off with phenadrine, AMP or straight 1,3 dimethylamylamine.
