Dymatize is a solid company that manufactures most of their supplements themselves which helps give decent quality supplements at an affordable price. Optimum Nutrition, PVL, Ultimate Nutrition, Universal, Maxx Essentials, Cytosport, Champion Nutrition, VPX, Interactive Nutrition, Controlled Labs, Weider (LOL), and a few others make their own also. With the continual price war that seems to be going on with supplements these days, these companies have an advantage over their competitors that outsource their manufacturing.
