Ive got some test 400. I haven never done a cycle, I work out regularly. I am 19 5'8 165 about 14-16% body fat. I want to get some muscle on me to fill out my extra skin from when i was 40 lbs heavier. I don't want anything crazy and i want to be able to keep most of it after i stop. Is 1cc a week going to bulk me a bit and let me keep it after?
