Desperate. Wanna try meds for stuttering.

Desperate. Wanna try meds for stuttering. So I searched up some medicines for stuttering. While no med is officialized by the FDA yet but some D2 receptor blocking drugs have shown some positive effects in small trials but the side effects are strong. Are any of you taking any kind of med for it? Does it help? I'm desperate so I'm gonna try to buy it without a doc's prescription.
