IronMag Labs Maximum Pump Extreme I'm a big fan of pwo and pump products. I got some of this in over the weekend. Took first scoop today. With in 10 to 20 minutes I felt it kick in and had not only good pumps but sweated a ton which is good for me. The taste was also very pleasing with a kool aid slash jolly rancher type flavor. I will use this for the rest of the month. Def worth the money.
