The steroid you took has nothing to do with this, it would not give you a moon face over night. That is not how this works. It would take weeks for this to happen and its only if you continue to use the steroid that this will happen, because your estrogen will rise with your testosterone rising, which is what gives you a moon face due to holding more water from heightened estrogen levels. Once you stop taking the steroid this will stop happening and you will not have the moon face from holding excess water from heightened estrogen levels.
Now I wrote all this because I didn't see that anyone addressed this from what I read, but in all honesty based on your posts you sound like your a 13 year old kid and not the person in those photos.
