What is your goal with steroids? Are you competing? At 8% body fat, but only 165 lbs I'm going to say you are not competing and have no intention of competing. You most likely have a body dis-morphia condition. You are too light to be a serious competitor in the top levels and you are too young to really need the help of these harsh substances to keep in shape. No, I get it! I have a slight case of body dis-morphia also and so yes I'm finishing my tren cycle and all that stuff as well, but I am also going in for a rotator cuff surgery in 3 weeks at age 47.
At your age the most I would do is an occasional blast of Testosterone and maybe a little Deca to put some weight on. Your natural systems though are probably in pretty good shape still and doing steroid cycles will destroy your natural system and you will find yourself on TRT in you 30s needing Viagra to get going, but hey it is your life and if pinning yourself in the rear 2X a week for the rest of your life sounds appealing go for it!!
