So yes, these are the first muscletech products I have ever considered trying. I got a pretty fat deal on them (both for $70). I am taking off until wednesday to decondition my CNS after my 20 rep squat workout. I did however go to the gym today for 45 minutes for some low intensity cardio, and a few sets of back and biceps. I took 2 scoops of nanovapor before working out. I have to admit I got a freaking awesome pump. The only thing I did not like is that I'm not used to that much caffeine or yohimbine hcl, and I was definitely feeling it. I felt like I was getting out of breathe significantly easier as well. I took one scoop of the anabolic halo afterwards, and have to admit that I feel that my muscles stayed pumped up for way longer than they usually would. On wednesday I will start logging my workouts on the nanovapor/halo stack, and let y'all know how it goes.
