muscles

I've never used steroids before but I want to try dianabol for 4 weeks just to get my feet wet and see what happens. wondering what you think would happen in my situation having really low body fat. I’m sub 7% Would my muscles get flatter or more swollen if I were to try 40 mg a day for a few weeks.

I'm a former baseball player from college. My height is 6 foot 4 oh, and my weight is 190 lb. My body fat is somewhere in the low teens. I have been Lifting for the past 5 years. Looking to add more muscle I need some advice on what direction I should go. Have my eye on using rad140 but not sure
