I watched the UFC fights last night and a lot of those guys are under contract with Xyience. They also ran commercials with the fighters endorsing the products. It usually seems like the supplement companies with the most hype are the most expensive (MuscleTech, InStone, VPX). Also, I think "proprietary blends" are bull and a way for companies to say, "we have this and that in our product", but not list how much. I want to know miligrams if I am going to shell out some cash for something.
