dude pick one or the other. all this flip flopping your doing to your body is going to jack it up. Either DEDICATE to a diet and do it or dont even try. Even if your Arms get down to 14, dont be scared of that crap. Your not gonna beef up to 17" arms and diet down and have 16" arms, come on dude. Reality check man. Take a break for a while, stay where your at and gradually put on some quality muscle. Wait 6 months or so to even try bulking, itd be a lot better for your body.
good luck man.
