B.S. in Nutrition, not going to register because it is not my career choice. Lam is right about it being subjective. In the body building community, clen would not be considered anabolic. In the nutritional sciences, it would be addressed in the ways it has both catbolic and anti-catabolic properties. Clen has highly catabolic properties (in the nutritional sciences). Catabolism is defined as: "reactions in which large molecules are broken down to smaller ones. Catabolic reactions usually release energy". Clen catabolizes fat big time. In BB we talk about catabolism in reference to muscle breakdown, but it applies to fat too (scientifically speaking). So, in BB terms we say it is anti-catabolic because it spares muscle breakdown. As far as science terminology is concerned, Clen is more of a catabolic agent because if you hold all other factors constant (diet, exercise, rest, etc.) and add clen, the net result would be increased breakdown of tissue (fat in this case). Clen has both catabolic (breakdown of fat) and anti-catabolic (preservation of muscle) properies. It is not anabolic in the steroid since. But, since it causes the body to use more fat for it's energy, it is protein sparing. This allows the protein ingested to be used to build new tissue (anabolism)--and therefore has anabolic properties, just as protein has anabolic properties. If you don't believe protein has anabolic properties--and is therefore anabolic--cut it out of your diet for a few weeks and post your results. I'd like to see if your protein intake affects your body's ability to build new tissue.
