JACK3D is back! A completely legal intenese pre-workout supplement. Years ago JACK3D was one of the most popular and most powerful pre-workouts on the market. It along with many other pre-workouts and fat burners was eventually taken off the market. USP Labs removed the DMAA, and added DMHA and Geranium Extract in it's place. It's now back with a better formula than ever!
