So i got a free sample of the stuff.  Im only 18 and I dont wanna mess around with testosterone boosters and such at this age but I figured one wouldnt kill me.  Today was one hell of a workout.  I havent used my no-x in about 6 days and i used this today...it was just weird.  I would of loved to see my bench if i had used this stuff.  I started with bi's doing 21's with the 70lb bar...which aint easy for me.  I normally struggle and can barely do the 60lb as where today i did 70 just for kicks and wow.  everything i did today with shoulders, bis, and my traps...everything felt huge.  The feeling i got felt as if i was on painkillers, it was very different but i felt way different than normal.  It was very noticeable.  Although i enjoyed it like i said im staying away from the stuff maybe until later in life.  I was wondering if anyone had any experience with the stuff or had any insight on it.  I cant find much about it online except for where to buy it.  Expensive too..
