I am 18, 174cm 74-75kgs 17% bodyfat (first 2 packs visible while flexing) I want to cut and I don't know what to use for max effect and minimal sides. I did some research on clen and it looks very good. So what should I choose clen or lipo 6 black with some bcaa. Don't forget that lipo causes bad jitters and clen preserves and even increases lean mass.
