BSN were possibly the originators of official supplement stacks. Muscletech made a clean attempt a few years back with the hardcore musclebuilding and weight loss stacks. Also the champion Jay Cutler stack. The issue that is most upsetting with these is the push to do both. Burn fat an put on muscle at the same time. Everybody has the right to their own opinion but very few companies today are doing the get big then the get lean stack. Example here is VPX with the MMA fight stack. Promotion muscle building Synthesize but at the same time zero impact bars and Clenbutrix. You want to learn how to make good stacks. Get some advice from the Animal Pak club.
