6'7 and only 215? you DO NOT need any steroid whatsoever, especially with bad joints or bones.. when you are that far underweight, which you are in a major way for your height, and then you use a steroid, it will put far too much pressure on tendons, ligaments and joints.. you also sound like you have less than zero education on any of this..
