OK, Hi everyone. Im 35 years old 5'8 175 pounds and 6% bodyfat.... Ive done cycles with tren and test before and ive never had any problems with estrogen or prolactin... I heard that I should always have caber and a AI on hand just in case but some have told me I should take it through out my cycle. The cycle im on right now is kinda a low dose. Im pining 100mg mon-wed-fri of Tren and the same with Test Prop... So should I worry about taking my caber and AI on a regular basis or should I only take it if needed??? Like if I begin to have sensitive nipples and erection problems?
