Well, if you start getting gyno from the deca, the nolva isn't going to do jack. Gyno from deca is from progesterone, and not estrogen. If this does happen, winny might help.
The test aromatizing along with the dbol is what I am concerned about. That is where the nolva might come in handy. But if it doesn't affect you, great, one less problem to worry about.
Well, it looks like this is a good cycle. How much are you wanting to gain? 20-25 pounds? Less?
