So for anxiety and depression we can act on brain receptors but for stuttering we cannot... doesn't make much sense to me... I m sorry man but it s not I won t try a drug which could improve the symptoms of a disturb that conditioned all my life because you are terrified... I guess you will lean to live with that Not to mention that the drug is being trialled by scientists at the moment and risks benefits will be assessed as per current regulations...so no, we won t buy a drug in the streets, it s 2021.
