I can't really say what you will gain becuase it depends on the person, expect anywhere between 15-25 pounds. If you are gyno prone have nolva on hand and run some liquidex at .25-.5mg's per day. Take your clomid post cycle and you will be good. I would also throw some Eq in there to compliment the Test, it will add some quality muscle and add some vascularity depending on your diet. Goodluck
