Muscle cannot change into flab....you may likely lose some muscle tissues, as you would not have significantly high hormone levels like you do on cycle, but the muscle will not morph into another kind of tissue such as fat. This is biologically impossible, just as it is impossible for water to turn into gold. You see?
Somebody mentioned to me the other day how they wanted to change their fat into muscle. They were serious, so I tried to explain that you cannot turn adipose tissue into muscle tissue. He gave me a quizzical look and thought I was crazy. lol
Also...Nolva is also known as Nolvadex, and Tamoxifen Citrate.
