I have bought some of the MuscleTech products over the years and have come to the conclusion;
NitroTech- overprized and useless.
Nortesten- overprized and useless.
CellTech- not so overprized and useful!

Of their products I can only recommend one; CellTech. I had some good pumps with that creatine and dextrose, of course I paid some good money for it too, but of all their products and of those I tested, the only one I want to buy again is CellTech ´cause of it´s pump quality...
