currently in week 6 of a Test E only cycle at 250mg per week. my nipples are sensitive/itchy sometimes and i've gained some weight and feel that my sex drive has decreased. i don't feel that my strength (or mood) has really improved. i plan on taking Nolvadex but am not sure how do use it during and after my cycle. i've read that 10mcg during and 20mcg post cycle. what do you think?
