Jack3d Supplement Review

USPLabs Jack3d is my personal pre-workout supplement of choice. Jack3d remains superior to it’s competitor NO-Xplode with smaller servings, higher potency, and more importantly about $10 cheaper per bottle.

After a Jack3d workout my muscles felt like they had been worked to the point of utter exhaustion. After a Jack3d workout I would suggest eating a lot of food. If you are trying to gain muscle mass make sure your calorie intake is very high. Any pre-workout drink is useless without a good diet to back it.
