dude no way on the planet earth you should even have steroids in your vocabulary... anadrol will fucking destroy you at your size.. .
you have to get some more size or you are going to wreck yourself in terms of joints, ligaments, tendons, bones, etc... far too much strain being that undersized... you will grow too fast and with that small of a frame, its a bad idea man... you should be 25-30 lbs bigger and due to that, the amount of growth you have with steroids will be higher and it will crush you internally..
