Fred, honestly, don't waste your time and money. Supplement companies are essentially quack doctors of the 20th and 21st century. You can get extremely lean with UD2.0 diet and training, for example, but nowhere near muscular levels of drug users.
I tried it myself, for seven months. I looked great, but for my height not overly muscular. 6', 174lbs, 7% BF.
