After gaining 30 lbs of mass in about 3-4 mnths, I plateaued (sic?). I tried Pink Magic and various other things to get me over the **** but no avail. Arimatest has helped ALOT. Im not putting on any extra lbs but noticing huge differences in strength. I am lifting a great deal more. Stacking w Jack3d, amplified creatine, ON whey, lots of glutamine and arginine. Pretty simple.
